released a tiny quality-of-life update to the registry directory you can now view the registry's README and quickly learn more about shadcn registires in one place without opening a new tab.

- Anthropic released Claude Opus 5.5 on September 22, 2026, matching Claude Fable 5.1 performance at 40% lower cost than Opus 5. - Model shows strongest alignment scores in Anthropic's behavioral audit and improved resistance to prompt injection attacks. - Input/output tokens priced at $4/$20 per million (20% cheaper), cache reads at $0.20 per million (60% cheaper); generation speed improved over 30%. > Opus 5.5's substantial cost reduction and efficiency gains (particularly 60% cheaper cache reads) could accelerate adoption of Claude for agent-based and coding workloads in AI infrastructure, while its improved alignment metrics suggest Anthropic is maintaining safety focus alongside capability scaling.

Newly released footage shows a woman carefully removing a fishing hook from a shark’s mouth after it was reeled ashore in Cape Hatteras, North Carolina, on July 4. Bystanders watched as she worked to free the shark before quickly returning it back into the ocean.

OpenAI released GPT-6 Sol and Luna with API prices cut in half, and Anthropic released Claude Opus 5.5, the first Claude 5.5 model, at roughly Fable 5.1 level for 40% less than Opus 5, with Sonnet 5.5 and Haiku 5.5 announced for the coming weeks - GPT-6 Sol and Luna are trained like Astra (still the top model), cost 50% less than GPT-5.6 promotional pricing ($2/$10 and $0.10/$0.50 per million tokens), get 90% off cached input reads plus cache-safe effort and tool toggles, write shorter and clearer, show fewer misleading claims about coding work, and roll out gradually today in ChatGPT Work (not yet in Chat), Codex and the API for paid users, Luna in the desktop app for Free and Go - Opus 5.5 costs $4/$20 per million tokens with $0.20 cache reads, $2/$10 batch and $8/$40 fast mode, outputs over 30% faster than Opus 5, writes clearer, thinks more per turn, reads charts and screenshots better, keeps zero data retention and adds EU AI Act watermarking - Anthropic is raising the 5-hour usage limits on Pro, Max, Team and seat-based Enterprise plans and giving subscribers a rate limit reset they can save and use whenever they choose, similar to the banked resets OpenAI previously added to Codex - Opus 5.5 scores best on Anthropic's behavioral audit and gets Fable 5.1-class safeguards - offensive cyber work falls back to Opus 4.8, dual-use biology and a small set of frontier LLM development tasks (like kernel development for certain ML accelerators) fall back to Opus 5

We released some new ideas and data on how to measure: 1) the extent to which AIs are being used to build next-gen AI models, 2) how we exercise oversight over increasingly autonomous agents, and 3) how compute is allocated. Measurements like these will be essential to future AI policy regimes. Enjoyed contributing to this work!
