This must be Opus 5. The pressure， especially on Anthropic， is mounting by the hour.

OpenAI has caught up with GPT-5.6 and the fantastic community work， and has rightly received a great deal of praise.

At the same time， Chinese open-source models are getting ever closer to even Anthropic's SOTA models.

Rumor has it that Opus 5 will outperform Fable 5. I don't think that's unrealistic. However， a new version of Fable 5 would then have to be released either simultaneously or shortly thereafter， because Anthropic would under no circumstances undermine its own SOTA class model.

In any case， July is going to be hot.
