# Nano Banana Pro/2 Stable Today, Safe to Scale Up · Stable Model Names Verified

> Today gemini-3-pro-image (Nano Banana Pro) and gemini-3.1-flash-image (Nano Banana 2) are running smoothly and safe to scale up. We tested the non -preview stable model names and image output is identical to preview — likely just a routine name promotion on Google's platform, not a retraining-level new model.

✅ **Nano Banana Pro/2 stable today, safe to scale up · stable model names verified** —— Today both `gemini-3-pro-image` (Nano Banana Pro) and `gemini-3.1-flash-image` (Nano Banana 2) are running smoothly and safe to scale up. We also tested the stabilized model names (without `-preview`): image output is **essentially unchanged** vs the `-preview` versions. This looks like a routine model-name promotion on Google's platform, not a retraining-level new model. Both old and new names work normally.
