Nano Banana Pro and Nano Banana 2 officially released

Nano Banana Pro与Nano Banana 2正式发布

Google AI Developers released Nano Banana Pro and Nano Banana 2, two image models available for production use through the Gemini API; the post names gemini-3-pro-image and gemini-3.1-flash-image but does not disclose pricing, benchmarks, or rate limits.

Why it matters: HKR-H/K/R all pass: Google shipped two production image models via Gemini API. The post gives no benchmarks, pricing, or safety mechanism, so this stays in the 78–84 band rather than p1.
