We added support for the latest AI models when using Kai with your own API key (BYOK):

OpenAI

  • GPT-5.5

  • GPT-5.4

  • GPT-5.4 Mini

Google

  • Gemini 3.5 Flash

  • Gemini 3.1 Pro

We also tidied up the model picker:

  • Newest models now appear at the top of each provider.

  • Older models (Gemini 2.5 Flash, Gemini 2.5 Pro, GPT-4.1, GPT-5 Mini, GPT-5.1, GPT-5.2) moved into a Legacy Models section that stays collapsed by default. Existing selections keep working.
