OpenAI dropped GPT-5.5 on April 23, 2026, and it is now the most capable ChatGPT model the company ships. GPT-5.5 scores 93.6% on GPQA Diamond, 82.7% on Terminal-Bench 2.0, and 78.7% on OSWorld-Verified, all ahead of GPT-5.4, while its Pro variant pushes BrowseComp to 90.1% and FrontierMath Tier 4 to 39.6%. In under nine months, OpenAI has shipped six distinct versions of GPT-5, each with its own identity and price point. If you have lost track of what separates GPT-5.0 from GPT-5.5, this guide covers every model in the family, release dates, context windows, benchmarks, pricing, and the key differences that actually matter. We also look ahead at what ChatGPT […]

DeepSeek released V4-Pro and V4-Flash on April 24, 2026, open-source MoE models with 1M context, new CSA/HCA hybrid attention, and benchmarks rivaling GPT-5.4 and Claude Opus 4.6. Full breakdown of architecture, benchmarks, pricing, and comparisons.

On April 23, 2026, OpenAI introduced GPT-5.5, its most capable model to date and the first fully retrained base model since GPT-4.5. The release brings state-of-the-art scores on Terminal-Bench 2.0, OSWorld, and GDPval, a much stronger agentic coding profile in Codex, a new Pro tier, and a pricing step up that reflects the jump in intelligence. GPT-5.5 is rolling out to Plus, Pro, Business, and Enterprise users across ChatGPT and Codex. GPT-5.5 Pro is available to Pro, Business, and Enterprise tiers. For anyone using Fello AI on Mac, iPhone, or iPad, GPT-5.5 will be available in upcoming weeks alongside Claude 4.6, Gemini 3, DeepSeek, Kimi-K2.6, and Perplexity in the same […]

A nameless AI model called Hunter Alpha appeared on OpenRouter, topped the leaderboards, and fooled thousands into thinking it was DeepSeek V4. It turned out to be Xiaomi’s MiMo-V2-Pro, a trillion-parameter model rivaling GPT-5.2 at a fraction of the cost.

On February 5, 2026, Anthropic released Claude Opus 4.6 — the latest and most capable model in its Claude lineup. Arriving just three months after Opus 4.5, this release brings a 1-million-token context window to the Opus family for the first time, introduces collaborative agent teams in Claude Code, and delivers benchmark results that put it ahead of GPT-5.2 and Gemini 3 Pro across most evaluations. But the headline number that caught the industry’s attention wasn’t a benchmark score. It was 500 — the number of previously unknown security vulnerabilities Opus 4.6 discovered in open-source code during pre-release testing, with little to no human prompting. This article breaks down everything […]

The last twelve months have been crazy for AI, and especially for image generation: Midjourney v6, FLUX.2, Seedream 4.5, Nano Banana Pro, and GPT-Image-1.5 have all tried to grab market share. With each new release, the line between synthetic and real continues to blur — and two of the most talked-about contenders in late 2025 are OpenAI’s GPT-Image-1.5 and Google’s Nano Banana Pro. Both aim to make image generation faster, smarter, and more accessible — but they take very different approaches. OpenAI’s GPT Image line replaced DALL·E earlier this year and is now native inside ChatGPT and the API. GPT-Image-1.5, released globally on December 16, 2025, is the latest version […]

Today, November 25, 2025, Black Forest Labs released FLUX.2, a new family of image-generation models aimed directly at the high-end creative, marketing, and product-visualization markets. The company, founded in 2024 and known for its open-core approach to multimodal research, positions FLUX.2 as both a frontier-level image generator and a model that can actually hold up in real production workflows—something many AI tools still struggle with. The release comes at a busy time for image-generation models. OpenAI’s GPT-4o tools, Google’s Imagen 4 and Nano Banana Pro, Midjourney v6, and Stability’s SD3 are all fighting for attention. FLUX.2 enters the mix with a clear focus: photorealism, consistent references, reliable text, and practical workflow control. Here’s […]

On Wednesday, November 12, 2025, OpenAI unveiled GPT-5.1, a major mid-cycle upgrade to its flagship ChatGPT models. The update introduces two new variants — GPT-5.1 Instant and GPT-5.1 Thinking — both designed to make conversations faster, smarter, and more natural. According to OpenAI, GPT-5.1 is built to feel “warmer” and more human-like in tone, while also improving instruction-following and reasoning. The Instant model powers most everyday chats, offering a friendlier and more conversational style. The Thinking model, aimed at deeper reasoning tasks, adapts its “thinking time” based on complexity — responding quickly to simple questions and spending extra effort on hard ones. The rollout begins immediately for ChatGPT Plus, Pro, Go, and Business users, with Enterprise and Education accounts getting early access before […]

Alibaba’s AI stack just crossed a symbolic frontier. On September 5 2025, the company’s cloud division unveiled Qwen-3-Max-Preview (Instruct), a 1-trillion-parameter large-language model that immediately takes its place among the most complex systems ever deployed and the most powerful AI models. The rollout began quietly inside Qwen Chat and Alibaba Cloud Model Studio. Soon coming to Fello AI. Only a few months ago, OpenAI’s GPT-4o, Google DeepMind’s Gemini 2.5, and Anthropic’s Claude Opus 4 each claimed slices of the “frontier-model” crown. Meanwhile, China-based challengers have been racing to close the capability gap. By releasing a one-trillion-parameter model, Alibaba is making it clear it wants to compete at the very top, not on the sidelines. […]

Moonshot AI, Chinese startup backed by Alibaba and Tencent, is rolling out an upgraded version of its open‑weight open-source large language model, Kimi K2. The new build Kimi K2‑0905, introduces a 256,000-token context window, improved coding performance, and retains its permissive modified MIT license. Although early beta access was briefly mentioned on the company’s Discord before details were removed, the model is now fully available to the public. Weights and a complete model card are live on Hugging Face, making it easy for developers to download, run, and fine-tune the model locally. Moonshot’s Meteoric Rise Founded in March 2023, Moonshot AI has grown at breakneck speed. In just over a year, the startup […]
