Nano Banana Pro — AI Image Generator

About Nano Banana Pro

Features

• Accepts up to 14 reference images in one request and can hold the likeness of up to 5 people consistent across the composition.
• Google's developer guide describes combining up to 6 high-fidelity object inputs in a single output, useful for loading a whole style guide of logos, palettes, and product shots.
• Studio-style local controls let an edit change camera angle, focus and depth of field, color grading, and scene lighting, including day-to-night relighting and added bokeh.
• Outputs at 1K, 2K, or 4K resolution across a wide aspect-ratio range, from 1:1 and 9:16 through cinema formats like 2.39:1 up to 4:1 banners.
• Translates and localizes text inside an existing image, redrawing signage or packaging copy in another language while keeping the design.
• Optional grounding with Google Search pulls real-time information into an edit, and every output carries a SynthID watermark.

What people use it for

• Brand and marketing work that composites many reference assets into one on-style visual.
• Localizing a finished design for international markets by translating the text baked into the image.
• Turning sketches or product photos into polished renders and 3D-styled mockups.
• Photo post-production requests such as relighting, refocusing, or regrading a shot without manual masking.
• Multi-person scenes, like team or family composites, where every face must stay recognizable.

Reported strengths

• DeepMind's model page reports leading Elo scores for image editing among competing models at release.
• In-image text rendering error rates mostly under 10 percent across languages, per DeepMind's published comparison, which made legible paragraph-length text practical.
• The 14-reference-image budget and 5-person consistency give it unusually large compositing capacity.
• Reasoning inherited from Gemini 3 Pro helps it follow long, multi-constraint edit instructions accurately.

Reported limitations

• Google's own developer post says it comes with higher cost and latency than Gemini 2.5 Flash Image, so it suits final assets more than rapid iteration.
• Free and lower-tier Gemini surfaces apply a visible watermark to outputs; Google removes it only for its top subscription tier, and SynthID is embedded regardless.
• On Google's consumer apps, free users get a limited quota before requests fall back to the older Nano Banana model.
• Since February 2026 Google itself has defaulted most surfaces to the newer Nano Banana 2, positioning Pro as a specialized rather than everyday choice.
