Veee(@vikktorrrre):It's been more than a month since Opus 5.5 dropped. It's still the best model we can actually USE, and Fable 5.5 is coming soon. What happened to other labs? Google's Gemini 4 Carbon beat Opus 5.5 by one point, but only a small group of Cyber defenders can use Carbon. Meta's best model, Muse Wonder Full, isn't even on the API. OpenAI scrapped the GPT-6.1 Astra launch after the model fell short of OpenAI's safety standards :(

Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
