New
Improved

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
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.
