What's new in Nano Banana 2.1

Sharper 1K / 2K / 4K output

Better instruction following and finish quality than Nano Banana 2 — closer to production-ready without Seedream pricing.

Up to 14 reference images

Fuse identity, outfit, and product refs in one shot. Reeldo supports up to 4 uploads in the UI; the model accepts up to 14.

Readable text & infographics

Headlines, sublines, and labeled diagrams stay legible — built for launch posters and explainers.

Clean ultra-wide ratios

21:9, 4:1, and other wide formats with reduced tiling artifacts — ideal for cinematic start frames.

Product recontext

Drop a SKU into a new scene from a single product photo — lifestyle, retail, or seasonal backgrounds.

Thinking mode for hard prompts

Switch to Thinking when the layout is complex — multi-ref character shots, typography-heavy posters, or structured infographics.
