Google: Nano Banana Pro (Gemini 3 Pro Image Preview)

Pricing, context window and lifecycle for google/gemini-3-pro-image-preview, tracked from what the vendor publishes.

2026-06-25 - 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.
