On May 28, 2026 Google announced two new Gemini models for the API: gemini-3.1-flash-image (code‑named Nano Banana 2) and gemini-3-pro-image (Nano Banana Pro). Both are now generally available for developers to generate images via the API.
Why it matters
They give developers higher‑quality, cost‑effective image generation directly through Gemini’s API.
