Compare leading AI models & Understand which is the best model for your needs. [Updated 15th of July]
July 2026 opens with Claude Fable 5 back online. On July 1, Anthropic redeployed its Mythos-class flagship after the US government lifted the June 12 export-control order that had pulled the model offline for nearly three weeks. The month’s other headlines all landed in the final week of June: OpenAI previewed the GPT-5.6 family (Sol, Terra, Luna) on June 26 but gated it behind a US-government access list of roughly 20 organizations, Elon Musk revealed Grok 4.5 in private beta on June 28 with no public release date, and Meituan open-sourced LongCat-2.0, a 1.6-trillion-parameter coding model trained entirely on Chinese chips, on June 29. Anthropic also made Claude Sonnet 5 its new default model on June 30, taking the writing crown and closing much of the gap to Opus 4.8. The model still to watch is Gemini 3.5 Pro, now cleared for a July general-availability launch after slipping from June.
The underlying board has not moved. Claude Opus 4.8 (May 28) still holds the #1 spot on the Artificial Analysis Intelligence Index at 61, ahead of GPT-5.5, Gemini 3.1 Pro, and Grok 4.3. Because GPT-5.6, Grok 4.5, and Gemini 3.5 Pro are all still gated, in private beta, or in limited preview, the models you can actually buy and use this month are unchanged from June. Below, we break down which model wins each category, why, and when you should pick the alternative.
GPT-5.5 is the best AI model for daily chat and knowledge work at Intelligence Index 59-60, the newly returned Claude Fable 5 is the best for coding at 80.3% SWE-Bench Pro (with Claude Opus 4.8, #1 overall at Intelligence Index 61, the everyday-value pick right behind it), Gemini 3.1 Pro is the best for hardest-mode reasoning and accuracy at Intelligence Index 57, Gemini 3.5 Flash is the best for price-performance at the frontier at Intelligence Index 55, Qwen 3.7 Max is the best mid-tier value pick at Intelligence Index 57, the new Claude Sonnet 5 (launched June 30) is the best for writing style and instruction-following, ChatGPT Images 2.0 is the best for image generation with readable text, Google Veo 3.1 is the best for AI video after OpenAI retired the Sora 2 consumer app, Grok 4.3 is the best for real-time X and web context, and Gemini Spark plus Claude Cowork are the two AI agents most worth your attention right now.
AI models change fast. New versions are released, performance shifts, and strengths evolve over time. To keep this comparison accurate and up to date, we publish a Best AI of the Month analysis every month, based on the latest model updates and real-world performance. Below are our most recent monthly rankings, where we take a deeper look at how the leading AI models performed during each month.
Claude Sonnet 5, launched June 30, 2026, is the new best for writing style, voice fidelity, and complex instruction-following. It jumps roughly 223 GDPval-AA Elo over Sonnet 4.6 (which held 1,643) to lead Artificial Analysis’s professional-writing benchmark ahead of Opus 4.8 and GPT-5.5, ships with a 1M-token context, and is the free and Pro default on claude.ai at introductory pricing of $2 / $10 per 1M tokens (then $3 / $15 after August 31).
GPT-5.5 serves as OpenAI’s primary everyday default chatbot. Launched on April 23, 2026, it boasts a 60% drop in hallucinations compared to GPT-5.4 and is available free in ChatGPT or at $5 / $30 per 1M tokens via API. Its successor, GPT-5.6, is in a gated preview limited to roughly 20 organizations and is not yet publicly available.
ChatGPT Images 2.0 holds the top crown for rendering precise multilingual text and infographic-style layouts. It is included in ChatGPT Plus and Pro plans, while the refreshed Nano Banana Pro stack serves as the photoreal alternative.
Google Veo 3.1 is the premier video-generation model left standing following the official discontinuation of Sora 2 on April 26, 2026. It is easily accessible within the Gemini app, Google AI Studio, and Vertex AI.
Claude Fable 5 returned on July 1 and retakes the coding crown at 80.3% on SWE-Bench Pro, the highest of any model you can use. This Mythos-class flagship is purpose-built for long-horizon agentic runs at $10 / $50 per 1M tokens. Claude Opus 4.8 is the everyday-value pick right behind it at $5 / $25, leading Anthropic’s SWE-bench Verified rankings and the favourite inside Cursor and Claude Code, with Gemini 3.5 Flash as the budget alternative.
Grok 4.3 features the most permissive guardrails of any frontier model. Coupled with its native real-time X news feed integration, it easily generates downloadable files such as PDFs and spreadsheets for $30/month via SuperGrok. Grok 4.5 was revealed in private beta on June 28 but has no public release date yet.
Gemini 3.1 Pro scores 94.3% on GPQA Diamond, 44.4% on Humanity’s Last Exam, and 77.1% on ARC-AGI-2. It features native, highly reliable Google Search grounding for real-time factual inquiries. Gemini 3.5 Pro is cleared for a July launch and could reset this ranking when it ships.
GPT-5.5 Pro achieves 39.6% on FrontierMath Tier 4, nearly doubling Claude Opus 4.8 Thinking’s 22.9% score. Qwen 3.7 Max is the value alternative, scoring an impressive 97.1 on the February 2026 HMMT math index.
Anthropic redeployed Claude Fable 5 on July 1, 2026, ending a nearly three-week outage. The US government had ordered the model pulled on June 12 under an export-control directive from Commerce Secretary Howard Lutnick citing national security; because Anthropic could not verify user nationality in real time, it disabled both Fable 5 and its unrestricted sibling Mythos 5 globally within hours. The restriction was lifted on June 30, and Fable 5 is available again on the Claude API, Claude.ai, Claude Code, and Claude Cowork. For Pro, Max, Team, and select Enterprise plans it is included for up to 50% of weekly usage limits through July 7, after which it runs on usage credits; API pricing is $10 per million input tokens and $50 per million output. Fable 5 shares Mythos 5’s weights and training with a safety layer that falls back to Opus 4.8 on roughly 5% of high-risk requests across cybersecurity, biology, and model distillation. It runs a 1-million-token context window, is built for long-horizon agentic work, and reclaims the coding crown at 80.3% on SWE-Bench Pro. Read our cover: Claude Fable 5.
Anthropic launched Claude Sonnet 5 on June 30, 2026 as the new default model for Free and Pro users on claude.ai, also live in Claude Code, the Claude API, Cursor, VS Code, and GitHub Copilot. It ships with a 1-million-token context window at introductory pricing of $2 / $10 per 1M tokens through August 31, 2026 (then $3 / $15). Sonnet 5 jumps roughly 223 GDPval-AA Elo over Sonnet 4.6 to lead the professional-writing benchmark ahead of both Opus 4.8 and GPT-5.5, and closes much of the agentic gap to Opus 4.8: 63.2% on SWE-Bench Pro (versus Opus 4.8’s 69.2% and GPT-5.5’s 58.6%), 84.7% on BrowseComp 25, and 88.3% on OSWorld-Verified against a 72.4% human baseline. It beats GPT-5.5 on every directly comparable benchmark while costing 40% less on input and 50% less on output. One caveat: an updated tokenizer maps the same text to roughly 1.0-1.35x more tokens, which narrows the real cost advantage.
Meituan open-sourced LongCat-2.0 under an MIT license, a 1.6-trillion-parameter Mixture-of-Experts model that activates an average of 48 billion parameters per token (dynamically 33-56 billion by query complexity) with a native 1-million-token context window. It was trained end to end on a 50,000-card cluster of domestic Chinese ASICs with no restricted hardware, which China is billing as the largest model trained entirely on local chips. LongCat-2.0 scores 59.5 on SWE-Bench Pro, narrowly ahead of GPT-5.5’s 58.6, and 70.8 on Terminal-Bench, with agentic coding as its focus. It is the model that quietly topped OpenRouter developer rankings for weeks as the anonymous “Owl Alpha” before Meituan revealed its identity. Weights are on Hugging Face and GitHub. Read our cover: LongCat-2.0.
Elon Musk confirmed on June 28 that xAI’s next model, Grok 4.5, is already running in private beta with teams at SpaceX and Tesla. It is built on a fresh V9 foundation with roughly 1.5 trillion parameters and Cursor-trained coding, but Musk gave no public release date. The model was originally targeted for late May, so it is running about a month behind, and a wider rollout within weeks is the likely next step. Until then, Grok 4.3 remains xAI’s public flagship and the model in our creativity ranking. Read our cover: Grok 4.5.
OpenAI previewed its GPT-5.6 family on June 26: Sol, the flagship; Terra, a balanced everyday model; and Luna, a fast and affordable tier. It is the first US frontier release gated behind government access, available initially through the OpenAI API and Codex to a limited group of roughly 20 organizations after OpenAI shared the models and release plans with the US government. General availability is planned for “the coming weeks,” and Sol is launching on Cerebras at up to 750 tokens per second in July. Announced API pricing is Sol $5 / $30, Terra $2.50 / $15, and Luna $1 / $6 per million tokens. Until GPT-5.6 opens up, GPT-5.5 remains OpenAI’s shipping flagship in our rankings. Read our cover: GPT-5.6.
Gemini 3.5 Pro remains the biggest pending launch. Google announced it at I/O on May 19 alongside Gemini 3.5 Flash, but only Flash shipped, and the June target slipped. As of late June the model was cleared for a July general-availability launch and is in limited preview for select Vertex AI enterprise customers, with Google citing quality refinements to coding, token efficiency, and long-task performance. Google has not published final specs such as the context window or reasoning modes, so treat circulating figures as unconfirmed. Use Gemini 3.5 Flash in the meantime; we will move 3.5 Pro into the main ranking the moment it goes live.
IplanRIO, the municipal IT company of Rio de Janeiro, released Rio 3.5 Open 397B, a fine-tune of Alibaba’s Qwen 3.5-397B-A17B base with 397 billion total parameters and 17 billion active per token, combined with SwiReasoning. It ships under an MIT open-weight license. First-party benchmarks claim it beats Qwen 3.7 Plus on four of five tests, including 70.8 on Terminal-Bench 2.1 versus Qwen’s 70.3, though these results are first-party and not yet independently verified. Read our cover: Rio 3.5 Open 397B.
Zhipu AI released GLM-5.2, a coding-first 744-billion-parameter Mixture-of-Experts model with 40 billion active parameters and a usable 1-million-token context window, up from GLM-5.1’s 200K. It launched first for GLM Coding Plan users, with the standalone API and MIT open-weight release following the same week. Read our full cover: GLM 5.2
Below, we provide a series of comprehensive, category-by-category deep dives to help you choose the ideal AI model for your specific operational goals. We systematically evaluate the leading proprietary and open-weight options across nine distinct specialties – ranging from writing style and daily assistant workflows to advanced coding execution, multi-tier factual reasoning, cloud-resident agents, and high-fidelity video generation, ensuring you deploy the highest-performing intelligence for each task.
The best AI for writing is Claude Sonnet 5, which Anthropic launched on June 30, 2026 as its new default model, with GPT-5.5 as the alternative for fact-anchored business writing and Claude Opus 4.8 as the alternative for long-form work where every sentence matters. Sonnet 5 jumps roughly 223 GDPval-AA Elo over Sonnet 4.6 (which scored 1,643) to reach about 1,866 and take the top of Artificial Analysis’s professional-deliverables benchmark, ahead of both Opus 4.8 and GPT-5.5, while keeping the Sonnet line’s lead on writing style, voice fidelity, and instruction-following in our hands-on tests.
It ships with a 1-million-token context window at introductory pricing of $2 / $10 per 1M tokens through August 31, 2026 (then $3 / $15), and is the new free and Pro default on claude.ai, so most writers get it at no cost; note its updated tokenizer maps the same text to roughly 1.0-1.35x more tokens, which narrows the real-world price gap. GPT-5.5 stays the safer default for fact-anchored writing like reports and briefs, the older Claude Sonnet 4.6 remains a cheaper legacy option at $3 / $15, Gemini 3.5 Flash (1,656 GDPval-AA Elo) is the price-performance pick for bulk content, and Claude Opus 4.8 is the call for long-form revision where you want the model to push back on weak arguments.
Model | Best For | Strength | Weakness | Price (per 1M tokens) |
|---|---|---|---|---|
Claude Sonnet 5 | Style + top GDPval-AA writing | New #1 GDPval-AA (~1,866), beats Opus 4.8 & GPT-5.5, 1M context | New tokenizer inflates token counts ~1.0-1.35x | $2 / $10 intro (then $3 / $15) |
GPT-5.5 | Business writing, factual reports | Improved factual reliability vs GPT-5.4 (OpenAI eval) | Style less expressive than Sonnet 5 | $5 / $30 |
Gemini 3.5 Flash | Bulk content, drafts at scale | 1,656 GDPval-AA Elo, 40% cheaper than Pro | Weaker on hardest reasoning | $1.50 / $9.00 |
Claude Opus 4.8 | Long-form, high-stakes copy | Best editor for argument structure | Most expensive option here | $5 / $25 |
Claude Sonnet 4.6 | Budget Claude writing | Prior Sonnet, 1,643 GDPval-AA | Superseded by Sonnet 5 | $3 / $15 |
Grok 4.3 | Casual, opinionated, X-style | Native X grounding, fewer guardrails | Not the natural pick for formal copy | $1.25 / $2.50 |
Runner-up and alternatives: Gemini 3.5 Flash is the runner-up for sheer volume at near-Sonnet quality, and GPT-5.5 is the runner-up for factual accuracy. Claude Opus 4.8 is the splurge pick for long-form. Grok 4.3 is the niche pick when you want X-style voice or live web context inside the draft.
What changed this month: Claude Sonnet 5 (June 30) is the headline writing launch, jumping ~223 GDPval-AA Elo over Sonnet 4.6 to lead the professional-writing benchmark ahead of Opus 4.8 and GPT-5.5, and it is now the free and Pro default on claude.ai. GPT-5.5 stays the pick for fact-anchored business writing, and Gemini 3.5 Flash (1,656 GDPval-AA Elo) remains the bulk-content value pick.
The best AI for everyday chat and daily assistant work is GPT-5.5 Instant, ChatGPT’s default model, with Claude Opus 4.8 as the alternative when you want a more thoughtful tone and Gemini 3.5 Flash as the budget alternative inside the free Gemini app. On high-stakes prompts, OpenAI reports GPT-5.5 Instant produces 52.5% fewer hallucinated claims than GPT-5.3 Instant, and 37.3% fewer inaccurate claims on conversations users had flagged for factual errors, on top of faster response times and a refreshed memory system that make it the most reliable default for general-purpose tasks. It is available inside ChatGPT (free with limits, Plus at $20/month, Pro at $100/month for roughly 5x Plus usage or $200/month for roughly 20x Plus usage), through the API as the gpt-5.5 model at $5 / $30 per 1M tokens, and bundled inside Fello AI alongside Claude, Gemini, Grok, and DeepSeek.
Claude Opus 4.8 is the better pick when you want a model that pushes back on weak prompts and reasons more carefully through ambiguous questions; Gemini 3.5 Flash is the better pick when you are running everything through the free Gemini app or care about speed.
Model | Best For | Strength | Weakness | Price |
|---|---|---|---|---|
GPT-5.5 Instant | Everyday chat, default assistant | 52.5% fewer hallucinated claims vs 5.3 Instant | Less expressive than Claude Sonnet 5 | $20/mo Plus; gpt-5.5 API at $5 / $30 |
Claude Opus 4.8 | Thoughtful, nuanced answers | Strong reasoning, pushes back well | $25 output API is the priciest here | $20/mo Pro, $5 / $25 API |
Gemini 3.5 Flash | Fast, free, multimodal | Free in Gemini app, 1M context | Weaker on hardest reasoning | Free / $1.50 / $9.00 API |
Grok 4.3 | Live news, X integration | Real-time X & web grounding | Smaller ecosystem | $30/mo SuperGrok |
Fello AI | All five models, one app | ChatGPT + Claude + Gemini + Grok + DeepSeek | Routed via app, not direct | $9.99/mo |
Runner-up and alternatives: Claude Opus 4.8 is the runner-up for thoughtful daily use, Gemini 3.5 Flash is the runner-up for fast/free, and Grok 4.3 is the niche pick for live-news heavy days. Fello AI is the natural pick if you want all five top models in one Mac/iOS app for $9.99/month instead of juggling subscriptions.
What changed this month: GPT-5.5 Instant stayed the default for chat with no regressions. Its successor GPT-5.6 (Terra for everyday work, Luna for speed) is in a gated preview limited to roughly 20 organizations and is not yet a consumer option. Claude Opus 4.8 holds the #1 spot on the Artificial Analysis Intelligence Index at 61, ahead of GPT-5.5. On the Claude side, the new default is Claude Sonnet 5 (June 30), a cheaper near-Opus model at $2 / $10 introductory pricing.
The best AI for image generation is ChatGPT Images 2.0, with Google Nano Banana Pro (Gemini 3 Pro Image) as the alternative for photorealism, Reve 2.0 as the layout-and-typography alternative, and Midjourney v8 as the alternative for stylized art. ChatGPT Images 2.0 (April 21, 2026) leads on text rendering, multilingual scripts, and infographic-style output, which makes it the natural pick when your image needs to contain words. Google’s Nano Banana Pro (Gemini 3 Pro Image, with the lower-cost Nano Banana 2 / Gemini 3.1 Flash Image as its sibling) is the natural pick for photoreal portraits and product shots, priced around $0.134 per 1K/2K image and $0.24 per 4K image. Reve 2.0 (June 3) jumped to #2 on the Arena text-to-image leaderboard with native 4K output and editing that preserves typography. Midjourney v8 stays the niche choice for distinctive style.
Model | Best For | Strength | Weakness | Price |
|---|---|---|---|---|
ChatGPT Images 2.0 | Images with readable text | Best multilingual text rendering | Less photoreal than Nano Banana | Included in ChatGPT Plus |
Nano Banana Pro (Gemini 3 Pro Image) | Photoreal portraits, products | Photorealism, ~$0.134 per 1K/2K image | Style less distinctive | Gemini app / AI Studio |
Reve 2.0 | Layout, typography, native 4K | #2 Arena, 16MP output, layout editing | New, smaller ecosystem | Free / from $7.99/mo |
Midjourney v8 | Stylized art, illustration | Aesthetic baseline most artists like | Weaker on text in image | $10-$120/mo |
Grok Imagine | NSFW / Spicy Mode | Most permissive guardrails | Smallest model behind | $30/mo SuperGrok |
MAI-Image-2.5 | Microsoft ecosystem | #3 text-to-image leaderboard, native in Copilot | Just launched, US-first | Included in Copilot |
Runner-up and alternatives: Nano Banana Pro is the runner-up overall and the leader for photoreal work; Reve 2.0 is the runner-up for layout and typography; Midjourney v8 is the niche pick for art-direction-heavy use. Grok Imagine is the only major model that allows Spicy Mode adult content.
What changed this month: No major image launches in July 2026. Reve 2.0 (June 3) still holds #2 on the Arena text-to-image leaderboard with native 4K rendering and layout-based editing, and Microsoft’s MAI-Image-2.5 (June 2) sits at #3, native in Copilot. ChatGPT Images 2.0 still leads on text-in-image.
The best AI for video generation is Google Veo 3.1, with Kling 3.5 as the alternative for fast iteration and Runway Gen-4 as the alternative for cinematic motion control. OpenAI retired the Sora 2 consumer web and app experience on April 26, 2026 (the Sora 2 API remains available to developers until September 24, 2026), so OpenAI no longer ranks in this consumer category. Veo 3.1 is available inside the Gemini app, Google AI Studio, and via Vertex AI, with native audio generation, 1080p output, and the strongest physics consistency in the current lineup. Kling 3.5 stays the speed pick at lower cost; Runway Gen-4 is the choice when you need precise camera control. Pika 2.0 and Luma Ray 3 remain credible alternatives for shorter clips.
Model | Best For | Strength | Weakness | Price |
|---|---|---|---|---|
Google Veo 3.1 | Highest-fidelity AI video + audio | 1080p, native audio, physics consistency | Compute-heavy, slower | Gemini AI Pro / Ultra |
Kling 3.5 | Fast iteration | Quick turnaround, strong motion | Less stable on long shots | From $10/mo |
Runway Gen-4 | Cinematic control | Best-in-class camera/motion control | Pricing premium | Free / $12 mo billed annually, or $15 monthly |
Pika 2.0 | Short clips, social | Cheap, fast, easy UX | Lower max resolution | From $10/mo |
Luma Ray 3 | Photoreal scenes | Strong realism for landscapes | Smaller community | Free / from $9.99/mo |
Runner-up and alternatives: Kling 3.5 is the runner-up overall and the cost-conscious pick; Runway Gen-4 is the runner-up for filmmakers and ad teams. Sora 2’s consumer app is retired; only the developer API remains, through September 24, 2026.
What changed this month: No major video launches in July 2026, so Veo 3.1 stays uncontested at the top of the still-supported video models. Google is widely expected to refresh Veo at its next AI event; we will update this section when that happens.
The best AI for coding is Claude Fable 5, which returned on July 1 after the US government lifted the June 12 export-control order that had pulled it offline. Anthropic’s Mythos-class flagship retakes the coding crown at 80.3% on SWE-Bench Pro, the highest score of any model you can use, and is purpose-built for long-horizon autonomous runs at $10 / $50 per 1M tokens. Claude Opus 4.8 is the everyday-value pick right behind it, holding Anthropic’s top SWE-bench Verified score, remaining the favourite inside Claude Code and Cursor, and costing half as much at $5 / $25. GPT-5.5 is the proprietary alternative, Gemini 3.5 Flash is the price-performance pick for agent-style coding, Qwen 3.7 Max is the mid-tier value pick, Nex-N2-Pro is the strongest open-weight pick at 80.8 SWE-Bench Verified, and MiniMax M3, LongCat-2.0, and Microsoft’s MAI-Code-1-Flash are the open-weight and budget alternatives.
Gemini 3.5 Flash (May 19) hit 76.2% on Terminal-Bench 2.1 and 83.6% on MCP Atlas at $1.50 / $9.00 per 1M tokens, making it the strongest price-performance option for agent workflows. On the open-weight side, MiniMax M3 (June 1) posts 59% on SWE-Bench Pro and 66% on Terminal-Bench 2.1 at roughly $0.60 per million input tokens, and Meituan’s new LongCat-2.0 (June 29, MIT) posts 59.5% on SWE-Bench Pro and 70.8 on Terminal-Bench, both edging GPT-5.5. Microsoft’s MAI-Code-1-Flash (June 2) beats Claude Haiku 4.5 on SWE-Bench Verified (71.6 vs 66.6) while using up to 60% fewer tokens, rolling out inside VS Code and the GitHub Copilot CLI. If you want to self-host, Kimi K2.6 (Modified MIT), GLM-5.2 (MIT, 1M context, built for long autonomous runs), and LongCat-2.0 are the strongest open-weight coders with clear commercial licenses.
Model | Best For | Strength | Weakness | Price (per 1M tokens) |
|---|---|---|---|---|
Claude Fable 5 | Best coding overall, long-horizon agentic | 80.3% SWE-Bench Pro, Mythos-class | Priciest; built for hours-long runs | $10 / $50 |
Claude Opus 4.8 | Everyday-value agentic coding | Anthropic-leading SWE-bench, adaptive thinking | Half the price, below Fable 5 on SWE-Bench Pro | $5 / $25 |
GPT-5.5 | Frontier proprietary alternative | 58.6% SWE-Bench Pro, 82.7% Terminal-Bench 2.0 | Less agent-tuned than Claude | $5 / $30 |
Gemini 3.5 Flash | Agent coding at scale | 76.2% Terminal-Bench, 83.6% MCP Atlas | Weaker on hardest reasoning | $1.50 / $9.00 |
LongCat-2.0 | Open-weight frontier coder | 59.5% SWE-Bench Pro, MIT, 1M context | New, self-host/provider only | Open weights (MIT) |
MiniMax M3 | Cheap frontier-class, self-host | 59% SWE-Bench Pro, 1M context, multimodal | Weights/license still rolling out | ~$0.60 input |
DeepSeek V4-Flash | Cheap open-weight coding | MIT, 1M context, II 47 | Below V4-Pro on hardest tasks | $0.14 / $0.28 |
Runner-up and alternatives: GPT-5.5 is the proprietary runner-up; Gemini 3.5 Flash is the runner-up for price-performance; Qwen 3.7 Max is the runner-up for mid-tier value; MiniMax M3, LongCat-2.0, and DeepSeek V4 are the runners-up for open-weight self-hosters. Inside IDEs, Cursor + Claude Opus 4.8 is the most popular pairing and Claude Code is the natural pick if you live in the terminal.
What changed this month: Claude Fable 5 returned on July 1 and retakes the best-coding pick at 80.3% SWE-Bench Pro, the highest of any usable model. Meituan open-sourced LongCat-2.0 (June 29), a 1.6T MIT model at 59.5% SWE-Bench Pro. OpenAI’s GPT-5.6 family (including a Codex-tuned Sol) began a gated preview on June 26 but is not yet generally available. Open-weight coding now has a deep bench: MiniMax M3 (II 55), LongCat-2.0, Kimi K2.6, and GLM-5.2 all sit at or above 58-59% on SWE-Bench Pro under permissive or commercial licenses. Anthropic’s new Claude Sonnet 5 (June 30) posts 63.2% SWE-Bench Pro at $2 / $10 introductory pricing, a cheaper near-Opus Claude coder.
The best AI for creative writing, brainstorming, and unfiltered ideation is Grok 4.3, with Claude Opus 4.8 as the alternative for structured creative work and Gemini 3.1 Pro as the alternative for multimodal creative tasks. Grok 4.3 (April 30, 2026) has the most permissive guardrails of any frontier model and the strongest native X integration, which makes it the natural pick for opinionated, on-trend, real-time creative work. Claude Opus 4.8 is the better pick when you want a model that holds a long creative thread, edits its own drafts, and engages with the substance of your work. Gemini 3.1 Pro is the better pick when your creative project mixes text with images, video, and live web context.
Model | Best For | Strength | Weakness | Price |
|---|---|---|---|---|
Grok 4.3 | Unfiltered, opinionated, on-trend | Fewest guardrails, X integration | Less polished for structured work | $30/mo SuperGrok |
Claude Opus 4.8 | Long-form structured creativity | Holds long threads, self-edits | Most cautious of the four | $20/mo Pro, $5 / $25 API |
Gemini 3.1 Pro | Multimodal creative | Strong text + image + video chain | Quotas inside Gemini app | Free / $2.00-$4.00 API in |
ChatGPT-5.5 | Mainstream creative writing | Best at hitting briefs | Heavier guardrails | $20/mo Plus, $5 / $30 API |
Grok Imagine (Spicy Mode) | NSFW / adult creative | Most permissive image generation | Niche use case | $30/mo SuperGrok |
Runner-up and alternatives: Claude Opus 4.8 is the runner-up overall and the right pick for projects that need to hold together across many turns. Gemini 3.1 Pro is the multimodal runner-up. For adult creative work, Grok Imagine Spicy Mode is the only frontier-grade option.
What changed this month: No major creativity-specific launches in July 2026. Grok 4.3 stayed the category leader; its successor Grok 4.5 was revealed in private beta on June 28 but has no public release date yet, so it does not change the pick this month.
The best AI for accuracy and research is Gemini 3.1 Pro, with Qwen 3.7 Max as the value alternative and GPT-5.5 Pro as the alternative for hallucination-sensitive work. Gemini 3.1 Pro leads the hardest pure-reasoning tests at 94.3% on GPQA Diamond, 44.4% on Humanity’s Last Exam, y 77.1% on ARC-AGI-2, with native Google Search grounding for live factual answers. Qwen 3.7 Max (May 20) entered the top tier at 92.4 on GPQA Diamond, tied with Claude Opus 4.8, at half the API cost.
GPT-5.5 Pro (April 23) carries GPT-5.5’s factual-reliability gains over GPT-5.4 (claims 23% more likely to be factually correct on OpenAI’s flagged-conversation set), which makes it the right pick when factual reliability matters more than raw benchmark depth. Gemini 3.5 Flash (May 19) outscores Gemini 3.1 Pro on coding and agent benchmarks but trails Pro on these accuracy tests (HLE 40.2% vs 44.4%, ARC-AGI-2 72.1% vs 77.1%), so Pro stays the accuracy pick.
Model | Best For | Key Benchmark | Weakness | Price |
|---|---|---|---|---|
Gemini 3.1 Pro | Hardest reasoning + research | 94.3% GPQA, 44.4% HLE, 77.1% ARC-AGI-2 | API quotas in app | $2.00-$4.00 / $12.00-$18.00 (tiered) |
Qwen 3.7 Max | Frontier accuracy at value pricing | 92.4 GPQA Diamond | API-only, no chat front-end | $1.25 / $3.75 promo; $2.50 / $7.50 list |
GPT-5.5 Pro | Hallucination-sensitive work | Improved factual reliability vs GPT-5.4 (OpenAI eval) | Pricier API tier | $100/mo ChatGPT Pro |
Claude Opus 4.8 | Long-form factual writing | #1 Intelligence Index (61) | Slower on hardest math | $5 / $25 |
Grok 4.3 | Live web facts | Native real-time grounding | Smaller benchmark coverage | $30/mo SuperGrok |
Runner-up and alternatives: Qwen 3.7 Max is the runner-up and the value pick at the frontier. GPT-5.5 Pro is the runner-up for hallucination-sensitive work. Claude Opus 4.8 is the runner-up for long-form factual writing.
What changed this month: No new accuracy leaders shipped, so Gemini 3.1 Pro holds the top of the category. The one to watch is Gemini 3.5 Pro, now cleared for a July general-availability launch after slipping from June; its specs are not yet public, but it could reset this ranking the moment it reaches general availability.
The best AI for hard problem-solving is GPT-5.5 Pro for FrontierMath-style abstract math and Qwen 3.7 Max for competition math, with Claude Opus 4.8 as the alternative for long agentic reasoning chains. GPT-5.5 Pro still leads at 39.6% on FrontierMath Tier 4 (nearly double Claude Opus 4.8’s 22.9%), which makes it the right pick when you need step-by-step working on the hardest math and physics problems. Qwen 3.7 Max (May 20) hit 97.1 on HMMT 2026 February, the highest score in its comparison group, and 44.5 on Apex, which makes it the right pick for competition-style problem-solving at half the cost of GPT-5.5 Pro.
Claude Opus 4.7 (April 16) introduced task budgets, a primitive for guiding agentic token spend on long chains; Claude Opus 4.8 (May 28) instead uses adaptive thinking controlled by an effort parameter, and does not support extended-thinking budgets. Gemini 3.5 Flash trades raw reasoning depth for speed and price; for the hardest problems, Gemini 3.1 Pro and the Thinking variants still lead.
Model | Best For | Key Benchmark | Weakness | Price |
|---|---|---|---|---|
GPT-5.5 Pro | Abstract math, physics | 39.6% FrontierMath Tier 4 | Highest cost tier | $100/mo ChatGPT Pro |
Qwen 3.7 Max | Competition math | 97.1 HMMT 2026 Feb, 44.5 Apex | API-only | $1.25 / $3.75 promo; $2.50 / $7.50 list |
Claude Opus 4.8 | Long agentic reasoning | Adaptive thinking, effort control, #1 Intelligence Index | Slower on math | $5 / $25 |
Gemini 3.1 Pro | Multimodal reasoning + research | 94.3 GPQA, 77.1 ARC-AGI-2 | API quotas | $2.00-$4.00 / $12.00-$18.00 (tiered) |
DeepSeek V4-Flash | Open-weight problem solving | MIT, 1M context, II 47 | Below V4-Pro on hardest | $0.14 / $0.28 |
Runner-up and alternatives: Claude Opus 4.8 is the runner-up overall and the natural pick for agentic, long-chain problem-solving. Gemini 3.1 Pro is the multimodal runner-up. DeepSeek V4-Flash is the open-weight runner-up.
What changed this month: No new problem-solving leaders shipped, so GPT-5.5 Pro still leads FrontierMath Tier 4 at 39.6% and Qwen 3.7 Max still leads competition math at 97.1 HMMT 2026 February. OpenAI’s GPT-5.6 Sol is the one to watch here once its gated preview opens up. The open-weight MiniMax M3 and LongCat-2.0 are strong cheaper options for agentic reasoning chains.
The best AI agent right now is Gemini Spark for 24/7 cloud-resident work and Claude Cowork for desktop-resident work, with ChatGPT Codex as the alternative for coding agents and OpenAI Operator-class browser agents as the alternative for web tasks. AI agents are the fastest-moving category of 2026: each top vendor now ships an agent product, and the practical choice is between agents that live in the cloud (run while your laptop is closed) and agents that live on your desktop (drive your apps directly).
Gemini Spark launched at Google I/O on May 19, 2026 and is the first 24/7 cloud agent. Claude Cowork launched in general availability on April 9, 2026 and runs as a desktop agent that drives your local apps. ChatGPT Codex Mobile (May 14) is the pick for coding-agent work, now usable from iOS and Android. Read the full Gemini Spark vs Claude Cowork comparison.
Agent | Best For | Where It Runs | Strength | Price |
|---|---|---|---|---|
Gemini Spark | 24/7 cloud tasks, Workspace workflows | Google Cloud VM (always-on) | First true 24/7 agent, deep Workspace integration | $100/mo Google AI Ultra |
Claude Cowork | Desktop, app-driving, design + code | Your Mac/Windows desktop | Drives local apps, sees your screen | $20/mo Claude Pro |
ChatGPT Codex Mobile | Coding agent on phone | OpenAI cloud + iOS/Android | Approve diffs and redirect work from phone | Included in ChatGPT plans |

OpenAI Operator-class | Browser tasks, web forms | OpenAI cloud + your browser | Web automation | ChatGPT Pro |
Runner-up and alternatives: Claude Cowork is the runner-up overall and the natural pick when you want the agent on your machine driving your apps. ChatGPT Codex Mobile is the runner-up for coding agents. Grok Agentic is the niche pick for real-time research.
What changed this month: No new consumer agents shipped, so the Gemini Spark (cloud) vs Claude Cowork (desktop) choice still drives most agent decisions for individual users. With Claude Fable 5 back online, the strongest model you can run inside an agent system for long-horizon autonomous work is available again. The open models LongCat-2.0, NVIDIA Nemotron 3 Ultra, and MiniMax M3 all ship strong agentic benchmarks, which matters for teams building their own agents on open weights.

Models are updated regularly so you always have access to the latest.
Update, July 2, 2026: Refreshed pricing, rollout status, and benchmarks for July, including Claude Opus 4.8 in the comparison. Grok 4.3 has now reached standard SuperGrok and X Premium+ seats, not just the $300 Heavy tier. For the deep dive, read our Grok 4.3 review. ChatGPT now runs on GPT-5.5,
GPT-5.5 sits at 59 on the Artificial Analysis Intelligence Index (#2 of 141 models), two points ahead of Gemini 3.1 Pro at 57. OpenAI’s April 23, 2026 launch flipped a dead heat into a clear ChatGPT lead on most head-to-head benchmarks, and Google answered on May 19, 2026 with Gemini
Claude hit #1 on the App Store in early 2026, pushing ChatGPT out of the top spot for the first time. The catalyst was Anthropic publicly refusing the Pentagon’s demand to deploy its models for autonomous weapons and mass surveillance, after which the government labelled Anthropic a “supply chain risk.”
Choosing the right AI tool in 2026 feels like trying to hit a moving target. New models arrive every few weeks, and what worked best in January might already be outdated today. This guide cuts through the hype to show you exactly which tools are winning right now based on
TL;DR: In January 2026, there isn’t one “best” AI for everything. On LMArena’s Text leaderboard, Gemini 3 Pro leads user-preference rankings, while the updated Artificial Analysis Intelligence Index v4.0 reports GPT-5.2 (with extended reasoning) as the top overall benchmark performer. Choose based on your task: Gemini for daily assistance, Claude
Update, July 2026: both models here have since been succeeded. Google has shipped Nano Banana 2 and Nano Banana 2 Pro, and OpenAI’s GPT Image line now powers ChatGPT Images 2.0. The head-to-head below is our original December 2025 test of GPT-Image-1.5 vs Nano Banana Pro, with the hands-on images

The open-weight tier had its biggest shake-up of the year, and it is now genuinely crowded at the frontier. The newest arrival is Meituan’s LongCat-2.0 (June 29), a 1.6-trillion-parameter MoE under an MIT license that posts 59.5% on SWE-Bench Pro and 70.8 on Terminal-Bench, trained entirely on domestic Chinese chips. Ranked by Artificial Analysis Intelligence Index, the strongest measured open models are MiniMax M3 at 55, Kimi K2.6 and Xiaomi’s MiMo-V2.5-Pro at 54, DeepSeek V4-Pro at 52, and GLM-5.1 at 51.4, with NVIDIA Nemotron 3 Ultra at 48 as the most capable model under a fully permissive license.
Several lines refreshed in the last month: Moonshot released Kimi K2.7 Code (June 12), Zhipu released GLM-5.2 (June 13), and Meituan open-sourced LongCat-2.0 (June 29), whose independent Intelligence Index scores are still pending. Licensing now matters as much as raw score: MiniMax M3’s terms were unconfirmed at launch, while Kimi K2.7 (Modified MIT), DeepSeek V4 (MIT), GLM-5.2 (MIT), LongCat-2.0 (MIT), and Nemotron 3 Ultra (OpenMDW) all clearly allow commercial use. Nex-N2-Pro (Nex AGI, Apache 2.0, 397B parameters) posts the strongest open coding scores here at 80.8 on SWE-Bench Verified and 75.3 on Terminal-Bench 2.1, putting it alongside GPT-5.5 on agentic coding. Rio 3.5 Open 397B (IplanRIO, MIT, 17B active) is a Qwen 3.5-397B-A17B fine-tune that reportedly beats Qwen 3.7 Plus on four of five first-party benchmarks, though those results are not yet independently verified.
Model | Best For | Key Benchmark | Context / License | Where To Run |
|---|---|---|---|---|
LongCat-2.0 | Newest frontier open coder | 59.5% SWE-Bench Pro, 70.8 Terminal-Bench, 1.6T/~48B active | 1M / MIT | Hugging Face, GitHub, OpenRouter |
MiniMax M3 | Highest open Intelligence Index | II 55, 59% SWE-Bench Pro, multimodal | 1M / license TBD | Hugging Face, API ~$0.60/1M |

NVIDIA Nemotron 3 Nano Omni | Edge / low-power | Multimodal, very small footprint | Compact / open | Local, NVIDIA tool |
Runner-up and alternatives: LongCat-2.0 y Kimi K2.7 Code are the newest picks when you need a clearly commercial license; MiniMax M3 still holds the highest measured Intelligence Index. DeepSeek V4-Pro and GLM-5.2 are the runners-up for agentic coding, DeepSeek V4-Flash is the cheapest way to get a 1M-context open model, and NVIDIA Nemotron 3 Nano Omni remains the natural pick for edge and on-device use. Xiaomi’s MiMo-V2.5-Pro (Intelligence Index 54) is also worth tracking as a fast-rising new entrant.
Every ranking on this page combines three inputs: public benchmarks (Artificial Analysis Intelligence Index, GPQA Diamond, ARC-AGI-2, Humanity’s Last Exam, SWE-bench Verified, GDPval-AA, FrontierMath, HMMT, Terminal-Bench, MCP Atlas, LM Arena), published API and subscription pricing from each vendor’s official pricing page, and hands-on use by the FelloAI editorial team running real prompts across the same task on every model. We re-fetch official pricing and benchmark sources before every monthly update.
Benchmarks are weighted to the use case: SWE-bench and Terminal-Bench drive coding, GPQA Diamond and ARC-AGI-2 drive accuracy, GDPval-AA (Artificial Analysis’s professional-deliverables benchmark) informs professional-task quality while writing style is judged primarily by hands-on testing, FrontierMath and HMMT drive problem-solving. We disclose when a benchmark is vendor-reported but not independently verified, and we strip any claim we cannot reproduce against a live source. When a model goes through a major upgrade between updates, we re-rank the category and add a “What changed this month” line at the bottom of the deep-dive.
It depends on the task. For daily chat and general assistance, GPT-5.5 Instant is ChatGPT’s default, with OpenAI reporting 52.5% fewer hallucinated claims than GPT-5.3 Instant. For coding, the newly returned Claude Fable 5 leads at 80.3% on SWE-Bench Pro, the highest of any usable model, with Claude Opus 4.8 (the #1 Intelligence Index model at 61) the everyday-value pick right behind it. For writing, the new Claude Sonnet 5 (June 30) leads the GDPval-AA professional-writing benchmark ahead of Opus 4.8 and GPT-5.5. For accuracy and research, Gemini 3.1 Pro at 94.3% GPQA Diamond and 44.4% Humanity’s Last Exam. For hard math, Qwen 3.7 Max hit 97.1 HMMT 2026 February, with GPT-5.5 Pro leading FrontierMath Tier 4 at 39.6%. For images, ChatGPT Images 2.0 leads on text rendering and Reve 2.0 is #2 on the Arena leaderboard. For agents, Gemini Spark is the first 24/7 cloud agent and Claude Cowork is the leader on desktop.
The month opens with Claude Fable 5 back online (July 1) after the US government lifted the June 12 export-control order that had pulled it offline. The other headlines landed in the final week of June: OpenAI previewed the GPT-5.6 family (Sol, Terra, Luna) on June 26 but gated it behind a US-government access list of roughly 20 organizations; Elon Musk revealed Grok 4.5 in private beta on June 28 with no public date; and Meituan open-sourced LongCat-2.0, a 1.6-trillion-parameter MIT coding model trained entirely on Chinese chips, on June 29. Anthropic also made Claude Sonnet 5 its new default model on June 30. Gemini 3.5 Pro is now cleared for a July general-availability launch after slipping from June. These follow the late-May and June board of Claude Opus 4.8 (#1 at 61), Qwen 3.7 Max, Gemini 3.5 Flash, Gemini Spark, and the open-weight wave of MiniMax M3, NVIDIA Nemotron 3 Ultra, Kimi K2.7, and GLM-5.2.
Yes. Anthropic redeployed Claude Fable 5 on July 1, 2026 after the US government lifted the export-control restriction it had imposed on June 12. It is available again on the Claude API, Claude.ai, Claude Code, and Claude Cowork. For Pro, Max, Team, and select Enterprise plans it is included for up to 50% of weekly usage limits through July 7, after which it runs on usage credits; API pricing is $10 / $50 per million tokens. Fable 5 is a Mythos-class model built for long-horizon agentic work with a 1M-token context, and it reclaims the coding crown at 80.3% on SWE-Bench Pro.
Claude Sonnet 5 is Anthropic’s new default model, launched June 30, 2026 for Free and Pro users on claude.ai and live in the Claude API, Claude Code, Cursor, VS Code, and GitHub Copilot. It ships with a 1-million-token context window at introductory pricing of $2 / $10 per 1M tokens through August 31, 2026 (then $3 / $15). It takes the writing crown with a ~223-point GDPval-AA jump over Sonnet 4.6 (beating Opus 4.8 and GPT-5.5) and closes much of the agentic gap to Opus 4.8 at 63.2% SWE-Bench Pro, while costing far less than GPT-5.5. The one caveat is an updated tokenizer that maps the same text to roughly 1.0-1.35x more tokens.
GPT-5.6 is OpenAI’s next-generation model family, previewed on June 26, 2026: Sol is the flagship, Terra is the balanced everyday model, and Luna is the fast, affordable tier. For now you probably cannot use it: it is the first US frontier release gated behind government access, available only through the OpenAI API and Codex to roughly 20 trusted organizations after OpenAI shared the models and release plans with the US government. General availability is planned for “the coming weeks,” with Sol launching on Cerebras at up to 750 tokens per second in July. Announced pricing is Sol $5 / $30, Terra $2.50 / $15, and Luna $1 / $6 per million tokens. Until it opens up, GPT-5.5 remains OpenAI’s shipping flagship.
Not publicly. Elon Musk confirmed on June 28, 2026 that Grok 4.5 is running in private beta with teams at SpaceX and Tesla, built on a fresh V9 foundation with roughly 1.5 trillion parameters, but he gave no public release date. It was originally targeted for late May, so it is about a month behind, and a wider rollout within weeks is the likely next step. Until then, Grok 4.3 remains xAI’s public flagship.
MiniMax M3 (June 1) has the highest measured Intelligence Index of any open model at 55, though its license was unconfirmed at launch. The newest heavyweight is Meituan’s LongCat-2.0 (June 29, MIT), a 1.6-trillion-parameter model at 59.5% SWE-Bench Pro trained entirely on Chinese chips. For a clearly commercial license, Kimi K2.7 Code (June 12, Modified MIT) is the newest coding-first leader; DeepSeek V4-Pro (MIT, II 52) tops open models on agentic real-world work; GLM-5.2 (June 13, MIT) runs a 1M-token context for long-horizon autonomous coding; and NVIDIA Nemotron 3 Ultra (June 4, OpenMDW) is the most capable model under a fully permissive license at II 48. DeepSeek V4-Flash is the cheapest 1M-context open model at $0.14 / $0.28 per million tokens.
Qwen 3.7 Max is Alibaba’s flagship API model, launched May 20, 2026 at the Alibaba Cloud Summit in Hangzhou. It scores Intelligence Index 57 on Artificial Analysis (top 10 globally, tied with Claude Opus 4.7, Gemini 3.1 Pro, and GPT-5.5 (medium)), 92.4 on GPQA Diamond, 97.1 on HMMT 2026 February, and 80.4 on SWE-Verified. List API pricing is $2.50 / $7.50 per 1M tokens with a 1M-token context window, plus $0.25 cached input (a 90% cache discount); a 50% launch promotion is still active into July, cutting it to $1.25 / $3.75 (cached input $0.125). Compared to GPT-5.5 at $5 / $30, Qwen 3.7 Max is half the input cost and a quarter of the output cost, but GPT-5.5 still leads on overall Intelligence Index (59-60) and on FrontierMath. For cost-sensitive agentic and long-context work where you want frontier-adjacent quality, Qwen 3.7 Max is the value pick.
The GPT-5.5 family launched April 23, 2026. The headline change is factual reliability: on a selected set of user-flagged conversations, OpenAI reports that GPT-5.5’s individual claims were 23% more likely to be factually correct than GPT-5.4’s, with full responses containing a factual error about 3% less often, plus faster response times across all tiers and a refreshed memory system. The consumer default is GPT-5.5 Instant (free with limits), and the gpt-5.5 API model runs $5 / $30 per 1M tokens. GPT-5.5 Pro is the higher-reasoning variant, available inside ChatGPT Pro at $100/month, and leads FrontierMath Tier 4 at 39.6%. Its successor GPT-5.6 is in a gated preview and not yet generally available.
Not on every benchmark, but it is still the best default. GPT-5.5 leads everyday chat, factual reliability, and writing reports. Claude Opus 4.8 is the better pick for coding and long agentic tasks and holds #1 on the Intelligence Index at 61. Gemini 3.1 Pro is the better pick for accuracy and research. Gemini 3.5 Flash is the better pick for price-performance. Qwen 3.7 Max is the better pick for cost-effective frontier work. ChatGPT remains the most polished consumer product overall and the natural starting point if you only pay for one model.
Gemini Spark is Google’s first 24/7 cloud-resident AI agent, launched at Google I/O on May 19, 2026 and exclusive to the Google AI Ultra plan, which Google restructured at I/O to include a $100/month entry tier and a $200/month top tier. Spark is built on Gemini base models with Google’s Antigravity harness on a Google Cloud VM, integrates with Gmail, Google Docs, and other Google Workspace apps, and can interact with Chrome and Android’s Halo system on the device side. It is worth the spend for users who have repeatable long-running workflows (inbox triage, research roll-ups, scheduled tasks). For one-off tasks, Claude Cowork at $20/month covers most desktop-agent needs.
On API pricing per million tokens, Gemini 3.5 Flash at $1.50 / $9.00 is the cheapest closed frontier-class model (it beats Gemini 3.1 Pro on coding and agent benchmarks at ~40% lower cost). MiniMax M3 at around $0.60 per million input tokens is the cheapest open-weight frontier coder, with LongCat-2.0 as a strong MIT alternative. Qwen 3.7 Max at $1.25 / $3.75 on its current promo ($2.50 / $7.50 list) is the cheapest at the top Intelligence Index tier, and for an open-weight model with a 1M context, DeepSeek V4-Flash at $0.14 / $0.28 is the cheapest by an order of magnitude. Note that OpenAI applies higher long-context rates to GPT-5.5 for prompts over 272K input tokens ($10 / $45 for GPT-5.5, $60 / $270 for GPT-5.5 Pro).
ChatGPT Free runs GPT-5.5 with usage limits. Gemini Free runs Gemini 3.5 Flash in the Gemini app and Google AI Studio. Claude Free runs Claude Sonnet 5 (the new default) with daily limits. DeepSeek Chat runs DeepSeek V4 free on the DeepSeek website. Grok has a limited free consumer plan (X Premium is a paid add-on). Qwen 3.5, NVIDIA Nemotron 3 Ultra, MiniMax M3, LongCat-2.0, Kimi K2.6, DeepSeek V4, and GLM-5.2 are open-weight and free to self-host. Qwen 3.7 Max is not free: it is API-only with no consumer chat front-end.
Claude Fable 5, back online since July 1, is the best for coding at 80.3% on SWE-Bench Pro, the highest of any usable model, and is built for long-horizon agentic runs at $10 / $50. Claude Opus 4.8 is the everyday-value pick right behind it at $5 / $25, the favourite inside Cursor and Claude Code. GPT-5.5 is the proprietary alternative at 58.6% SWE-Bench Pro and 82.7% Terminal-Bench 2.0. Gemini 3.5 Flash is the price-performance pick at 76.2% Terminal-Bench 2.1 and $1.50 / $9.00 per 1M tokens. On open weights, LongCat-2.0 (June 29, MIT, 59.5% SWE-Bench Pro) and MiniMax M3 (59% SWE-Bench Pro, ~$0.60 input) are the frontier picks, and Microsoft’s MAI-Code-1-Flash is the budget IDE pick. DeepSeek V4, Kimi K2.6, and GLM-5.2 round out the open-weight coders.
Claude Sonnet 5, launched June 30, 2026, is the best for writing style and instruction-following: it jumps roughly 223 GDPval-AA Elo over Sonnet 4.6 (1,643) to lead the professional-writing benchmark ahead of Opus 4.8 and GPT-5.5, and is the free and Pro default on claude.ai at $2 / $10 introductory pricing (then $3 / $15). GPT-5.5 is the alternative for fact-anchored business writing (improved factual reliability vs GPT-5.4). Gemini 3.5 Flash is the price-performance pick for bulk content at 1,656 GDPval-AA Elo and $1.50 / $9.00.
Gemini 3.1 Pro is the best for accuracy and research at 94.3% GPQA Diamond, 44.4% Humanity’s Last Exam, and 77.1% ARC-AGI-2, with native Google Search grounding for live factual answers. Qwen 3.7 Max is the value runner-up at 92.4 GPQA Diamond. GPT-5.5 Pro is the hallucination-sensitive runner-up. Gemini 3.5 Pro, cleared for a July launch, could take the top spot when it ships.
ChatGPT Images 2.0 is the best for images with readable text, multilingual scripts, and infographic-style output. Google Nano Banana Pro (Gemini 3 Pro Image) is the best for photoreal portraits and products. Reve 2.0 is #2 on the Arena text-to-image leaderboard with native 4K and layout-based editing. Midjourney v8 is the best for stylized art, and Grok Imagine is the only frontier model that allows Spicy Mode adult content.
Google Veo 3.1 is the best for AI video after OpenAI retired the Sora 2 consumer app on April 26, 2026 (its API runs until September 24, 2026). Kling 3.5 is the runner-up for fast iteration, Runway Gen-4 is the runner-up for cinematic control.
GPT-5.5 Pro leads abstract math at 39.6% FrontierMath Tier 4, included in ChatGPT Pro at $100/month. Qwen 3.7 Max leads competition math at 97.1 HMMT 2026 February and 44.5 Apex, at half the cost on API. Claude Opus 4.8 is the alternative for long agentic reasoning, using adaptive thinking and an effort parameter.
Grok 4.3 is the best for unfiltered, opinionated, on-trend creativity with the fewest guardrails and native X grounding, at $30/month SuperGrok. Claude Opus 4.8 is the alternative for structured long-form creative work, Gemini 3.1 Pro is the alternative for multimodal creative.
