Google's current workhorse image model (GA Oct 6, 2026) and the designated replacement for gemini-3.1-flash-image. Output billed per token: a 1K image is 1,120 output tokens at $30 per million. Input tokens tripled vs the predecessor ($1.50/1M), which matters for edit-heavy flows with many reference images.
