This ensures higher-quality image generation compared to generic text-to-image instructions.

What is the best way to prompt in-image typography for Nano Banana 2?

The best way to prompt in-image typography for Nano Banana 2 is to enclose the exact text you want rendered in quotes within your prompt. Use a subject-first declarative phrasing strategy to ensure the model accurately generates the specified text inside the image.

Can I batch generate multiple image variants and select aspect ratios on RunComfy?

Yes, you can batch generate image variants by configuring the num_images parameter in the JSON input schema. You can also select social-native aspect ratios, choose resolution tiers from 0.5K to 4K, and set output formats for your final drafts.

Does Nano Banana 2 support web grounding for real-world references?

Yes, Nano Banana 2 supports optional web grounding by enabling the enable_web_search parameter in the JSON input schema. This allows the text-to-image model to fetch real-world references for entities and events during image generation.

How do I refine and keep consistent image generation results across multiple drafts?

To refine and maintain consistent image generation results, use stable refinement via the seed parameter in the JSON input schema. Adjusting safety_tolerance and limit_generations also helps control output variation and generation limits across drafts.
