Google: Gemini 3.1 Flash Lite Preview

Pricing, context window and lifecycle for google/gemini-3.1-flash-lite-preview, tracked from what the vendor publishes.

2026-05-25 - its vendor retired this model on that date, and the catalogue still lists it. Anything still calling it is running on borrowed time.

To find every place that calls it:

curl -sO https://neosignal-ai.vercel.app/check.py
python check.py .

It names every model your repository calls that is already gone, and exits non-zero so the next one fails the build instead of production.
