What it does
Google's Gemini 3.1 Flash Lite Preview joined the model selector.
Before this
An addition to the selector. Gemini 3 Flash and the 2.x line were already there; 3.1 Flash Lite Preview is the cheaper, faster one, and being a preview model it tracks Google's release channel rather than ours.
Why it matters
Very fast and very cheap — the model to try first when an agent's volume is high and each answer is short.

Preview models track the provider's release channel rather than ours: they can change behaviour or be retired at short notice, so they are worth testing on and worth thinking twice about under a production agent.
