We've now received GPT-6 Astra and Opus 5.5.
Confirmed for the next releases are:
- Sonnet 5.5
- Haiku 5.5
- Kimi K3.1 (they themselves hinted at it in a cryptic post)
- Gemini 4, before the end of the year
Unconfirmed but very likely:
- Fable 5.5
- Astra update (at the DevDay?)
Currently, there's no word yet on new GLM or DeepSeek models.
