The current official Nano Banana image API has no free image-output tier for Lite, Nano Banana 2, or Pro. Lite is the lowest official 1K lane, while laozhang.ai's $0.025 Gemini Flash / Nano Banana route is a separate provider contract, not a Google price row.

Gemini 3.1 Flash Image currently costs $0.067 at 1K, $0.101 at 2K, and $0.151 at 4K on Google's direct pricing page, with 1K as the sensible default for most production work and batch cutting those rates roughly in half.
