Cursor 2.0 launched with Composer-1, an agentic coding model optimized for speed and precision, featuring multi-agent orchestration, built-in browser for testing, and voice-to-code capabilities. OpenAI released gpt-oss-safeguard models (20B, 120B) for policy-based safety classification, open-weight and fine-tuned from gpt-oss, available on Hugging Face and supported by inference stacks like Ollama and Cerebras. Goodfire and Rakuten demonstrated sparse autoencoders for PII detection matching gpt-5-mini accuracy at significantly lower cost. The Cursor 2.0 update also includes a redesigned interface for managing multiple AI coding agents, marking a major advancement in AI IDEs. "Fast-not-slowest" tradeoff emphasized by early users for Composer-1, enabling rapid iteration with human-in-the-loop.

OpenAI released the GPT-5 series including GPT-5-mini and GPT-5-nano, with mixed user feedback on performance and API behavior. Anthropic extended Claude Sonnet 4 context window to 1 million tokens, a 5x increase, enhancing large document processing. Zhipu AI launched the open-source multimodal GLM-4.5V model with improvements in RL scaling and agentic tasks. Google DeepMind showcased the video generation model Genie 3 and updated the Gemini App with new features like Deep Think and Gemini Live. Alibaba Qwen released the distilled image model Qwen-Image distilled and enhanced their Deep Research capabilities. Open source models like Skywork's Matrix-Game 2.0 and Jan.ai's Jan-v1 (built on Qwen3-4B-Thinking) were introduced, focusing on real-time world modeling and web search respectively. Developer tools such as Claude Code and Cursor were also highlighted.

OpenAI announced placing #6 among human coders at the IOI, reflecting rapid progress in competitive coding AI over the past two years. The GPT-5 launch faced significant user backlash over restrictive usage limits and removal of model selection control, leading to a reversal and increased limits to 3000 requests per week for Plus users. Confusion around GPT-5 naming and benchmarking was highlighted, with critiques on methodological issues comparing models like Claude and Gemini. Performance reviews of GPT-5 are mixed, with claims of near-zero hallucinations by OpenAI staff but user reports of confidence in hallucinations and steering difficulties. Benchmarks show GPT-5 mini performing well on document understanding, while the full GPT-5 is seen as expensive and middling. On the Chatbot Arena, Gemini 2.5 Pro holds a 67% winrate against GPT-5 Thinking. Prompting and model behavior remain key discussion points.
OpenAI rolls out GPT-5 and GPT-5 Thinking to >1B users worldwide; -mini and -nano help claim Pareto Frontier

OpenAI launched GPT-5, a unified system featuring a fast main model and a deeper thinking model with a real-time router, supporting up to 400K context length and aggressive pricing that reclaims the Pareto Frontier of Intelligence. The rollout includes variants like gpt-5-mini and gpt-5-nano with significant cost reductions, and integrations with products such as ChatGPT, Cursor AI, JetBrains AI Assistant, Microsoft Copilot, Notion AI, and Perplexity AI. Benchmarks show GPT-5 performing strongly in coding and long-context reasoning, roughly matching Claude 4.1 Sonnet/Opus on SWE-bench Verified. The launch was accompanied by a GPT-5 prompting cookbook and notable community discussions on pricing and performance.
