Nano Banana 2 Lite

Nano Banana 2 Lite (model ID gemini-3.1-flash-lite-image) became generally available on June 30, 2026 as the entry tier of Google's image family. Google describes it as its fastest and cheapest Gemini image model, built for ultra-low latency and for workloads where pictures are generated by the thousand rather than one at a time: catalogue thumbnails, variant testing, in-app avatars, bulk editing. It is the only model in the family that renders at 512 px, and it covers the widest set of aspect ratios — from square through 4:5 and 3:2 up to 21:9 — which matters when output has to drop straight into fixed layouts. Typical text-to-image latency is around four seconds. It also replaces the original Nano Banana (gemini-2.5-flash-image) as the recommended low-cost option, and Google steers users of that legacy model here. The economy shows where features were cut: unlike Nano Banana 2 and the Pro tier, Lite cannot ground a generation in Google Search, so it is a poor choice for pictures that must reflect current facts. At roughly USD 0.034 per 1K image — about half the price of Nano Banana 2 and a quarter of the Pro tier — it is priced accordingly. Outputs carry the same invisible SynthID watermark.
