Anthropic nuked OpenAI DevDay with Opus 5.5. Everyone attending will be talking about how much better Opus 5.5 is than Astra, how much more you can use it for the same price, and how Fable 5.5 will be even better. Of course, you can't trust Anthropic; also, they might nerf Opus 5.5 after OpenAI DevDay, and Fable is so expensive.
