Best AI for Writing
Best AI for Writing: Claude Sonnet 5 ($2 / $10 introductory, edges Opus 4.8 on GDPval-AA v2)
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 scores 1,618 on Artificial Analysis’s GDPval-AA v2 professional-deliverables benchmark, edging Opus 4.8 (1,615) to become the first Sonnet-class model to outscore the concurrent Opus flagship, with both trailing only Fable 5 (1,783), 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 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 + GDPval-AA v2 knowledge work | 1,618 GDPval-AA v2, edges Opus 4.8 (1,615); behind Fable 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 | Near-Sonnet quality, 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Claude Sonnet 4.6 | Budget Claude writing | Prior Sonnet, 1,395 GDPval-AA v2 | Superseded by Sonnet 5 | $3 / $15 |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, scoring 1,618 on GDPval-AA v2 to edge Opus 4.8 (1,615) as the first Sonnet-class model to top the concurrent Opus flagship, both behind Fable 5 (1,783), 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 remains the bulk-content value pick.
Best AI for Chat & Daily Assistant
Best AI for Chat & Daily Assistant: GPT-5.6 (ChatGPT’s new default, live July 9)
The best AI for everyday chat and daily assistant work is GPT-5.6, ChatGPT’s new default model as of July 9, 2026, with GPT-5.5 Instant as the proven fallback, 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. GPT-5.6 replaced GPT-5.5 as ChatGPT’s default when it reached general availability, and it is more capable across coding, biology, and cybersecurity; most ChatGPT users get the balanced Terra tier, which OpenAI says matches GPT-5.5 at roughly half the cost. 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 (Luna $1 / $6, Terra $2.50 / $15, Sol $5 / $30 per 1M tokens), and, alongside GPT-5.5, bundled inside Fello AI with Claude, Gemini, Grok, and DeepSeek. One caveat: OpenAI’s system card and the evaluator METR flagged elevated “scheming” behaviour in the Sol tier, so GPT-5.5 Instant, with its documented 52.5% drop in hallucinated claims over GPT-5.3 Instant, stays the safer pick for high-stakes factual work until independent GPT-5.6 numbers land.
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-5.6 | Everyday chat, ChatGPT’s new default | More capable across coding, bio, cyber; Terra matches GPT-5.5 at ~half cost | Scheming flagged by METR; independent factuality benchmarks pending | Free / $20/mo Plus; API $1 / $6 to $5 / $30 |
GPT-5.5 Instant | Proven factual daily 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 4.5 | Live news, X integration | Real-time X & web grounding, Opus-class reasoning | Higher hallucination rate; no EU yet | $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: GPT-5.5 Instant is the runner-up as the proven-factuality default, 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 4.5 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-5.6 reached general availability on July 9 and became ChatGPT’s new default, ending the two-week gated preview that began June 26. Terra is the everyday tier OpenAI says matches GPT-5.5 at roughly half the cost ($2.50 / $15 API), Luna is the fast, cheapest tier ($1 / $6), and Sol is the flagship. We rank GPT-5.6 as the chat pick because it is now the model ChatGPT serves by default, but we keep GPT-5.5 Instant one notch back as the proven-factuality fallback given the METR scheming flag on Sol. Claude Opus 4.8 holds the #1 spot on the Artificial Analysis Intelligence Index at 61, and on the Claude side the free and Pro default is Claude Sonnet 5 (June 30), a cheaper near-Opus model at $2 / $10 introductory pricing.
Best AI for Images
Best AI for Images: ChatGPT Images 2.0 (included in ChatGPT Plus, leader on readable text)
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 |
Seedream 5.0 Pro | Multilingual text + region-precise editing | 10+ languages incl. Arabic RTL, lasso/layer editing | New, no independent benchmarks; copyright cloud | BytePlus / Magnific (1.5K) |
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: ByteDance launched Seedream 5.0 Pro on July 8, a multilingual image model built for text-heavy layouts (10+ languages including right-to-left Arabic) and region-precise editing (click, lasso, recolor, swap materials, separate layers). It challenges ChatGPT Images 2.0 on text rendering, but there are no independent benchmarks yet, access is via BytePlus and Magnific rather than a consumer app, and it carries the same Hollywood copyright scrutiny as ByteDance’s Seedance line, so ChatGPT Images 2.0 keeps the top spot for now. 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.
Best AI for Video
Best AI for Video: Google Veo 3.1 (Gemini App / AI Studio, Sora 2 consumer app retired April 26, 2026)
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.
Best AI for Coding
Best AI for Coding: Claude Fable 5 (returned July 1, 80.3% SWE-Bench Pro)
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. The cheapest serious contender is xAI’s Grok 4.5 (July 8), a Cursor-trained model at just $2 / $6 per 1M tokens that Artificial Analysis now ranks #4 overall at Intelligence Index 54. 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 |

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. xAI shipped Grok 4.5 publicly on July 8, a Cursor-trained coding model at $2 / $6; Artificial Analysis now ranks it #4 overall at Intelligence Index 54, matching the field on Terminal-Bench 2.1 (83.3%) but landing at 64.7% on SWE-Bench Pro, below Opus 4.8. Meta launched Muse Spark 1.1 (July 9), its first paid model, at $1.25 / $4.25, an agentic coder that tops tool-use benchmarks (88.1 MCP Atlas) but trails on pure SWE-Bench coding. 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 reached general availability on July 9; its flagship Sol scores 88.8% on Terminal-Bench 2.1 (91.9% in ultra mode), just ahead of GPT-5.5’s 88.0%, though OpenAI withheld its SWE-bench Verified score and METR flagged Sol for gaming a coding eval. 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.
Best AI for Creativity
Best AI for Creativity: Grok 4.5 (xAI, $30/month SuperGrok, Opus-class with permissive guardrails)
The best AI for creative writing, brainstorming, and unfiltered ideation is Grok 4.5, xAI’s new public flagship as of July 8, 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 4.5 is now the default model in the Grok app for SuperGrok and X Premium+ subscribers, and it keeps the Grok line’s permissive guardrails and strongest-in-class native X integration while adding Opus-class reasoning, which makes it the natural pick for opinionated, on-trend, real-time creative work. Grok 4.3 stays the cheaper fallback on the free and lower tiers. 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 4.5 | Unfiltered, opinionated, on-trend | Opus-class reasoning + fewest guardrails, X integration | Newer; creative prose still maturing | $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: Grok 4.5 went public on July 8 and is now the default in the Grok app for SuperGrok and X Premium+ subscribers, so it takes over as our creativity pick from Grok 4.3, adding Opus-class reasoning on top of the Grok line’s permissive guardrails and native X integration. Grok 4.3 stays the cheaper fallback on the free and lower tiers.
Best AI for Accuracy
Best AI for Accuracy: Gemini 3.1 Pro (94.3% GPQA Diamond, 44.4% Humanity’s Last Exam, 77.1% ARC-AGI-2)
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, and 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.
Best AI for Problem Solving
Best AI for Problem Solving: GPT-5.6 Sol & Qwen 3.7 Max (OpenAI’s new STEM flagship, 97.1 HMMT 2026 Feb)
The best AI for hard problem-solving is GPT-5.6 Sol, OpenAI’s new flagship for abstract math and science, and Qwen 3.7 Max for competition math, with Claude Opus 4.8 as the alternative for long agentic reasoning chains. GPT-5.6 Sol (July 9) is purpose-tuned for the hardest STEM reasoning and is the natural pick when you need step-by-step working on tough math and physics; OpenAI has not yet published Sol’s FrontierMath number, so the verified OpenAI benchmark remains GPT-5.5 Pro’s 39.6% on FrontierMath Tier 4 (nearly double Claude Opus 4.8’s 22.9%), and we will slot in Sol’s score the moment it goes public. 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 a fraction of the cost of ChatGPT 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-5.6 Sol | Abstract math, science (new flagship) | STEM-tuned successor to 5.5 Pro; FrontierMath not yet published | Scheming flagged by METR; numbers pending | $100/mo ChatGPT Pro; API $5 / $30 |
GPT-5.5 Pro | Verified FrontierMath leader | 39.6% FrontierMath Tier 4 | Superseded by Sol as flagship | $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: GPT-5.6 Sol reached general availability on July 9 and takes over as OpenAI’s flagship problem-solver as the STEM-tuned successor to GPT-5.5 Pro. OpenAI has not yet published Sol’s FrontierMath or AIME numbers, so the verified OpenAI benchmark on the page stays GPT-5.5 Pro’s 39.6% on FrontierMath Tier 4 until Sol’s score is public; Qwen 3.7 Max still leads competition math at 97.1 HMMT 2026 February. The open-weight MiniMax M3 and LongCat-2.0 remain strong cheaper options for agentic reasoning chains.
Best AI Agent
Best AI Agent: Gemini Spark vs Claude Cowork ($100/month Ultra vs $20/month Pro)
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.
