Release: llm-gemini 0.31 (https://github.com/simonw/llm-gemini/releases/tag/0.31)

• gemini-3.1-flash-lite is no longer a preview (https://cloud.google.com/blog/products/ai-machine-learning/gemini-3-1-flash-lite-is-now-generally-available).

Here’s my write-up of the Gemini 3.1 Flash-Lite Preview model (https://simonwillison.net/2026/Mar/3/gemini-31-flash-lite/) back in March. I don’t believe this new non-preview model has changed since then.
