SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @runcomfy/cli.

What problem does it solve? Generating images with the Nano Banana 2 model requires knowing its prompting patterns, resolution tiers, aspect ratio options, and when to route to sibling models; this Skill packages that knowledge so prompts produce stronger output than naive usage. ## Core Features & Use Cases - Text-to-image generation: Calls runcomfy run google/nano-banana-2/text-to-image with a documented input schema covering prompt, num_images, seed, aspect_ratio, resolution, output_format, safety_tolerance, and enable_web_search. - Prompting guidance: Documents subject-first grammar, quoted in-image typography, seed locking for reproducibility, and anti-patterns to avoid. - Model routing advice: Explains when to use Nano Banana 2 versus Nano Banana Pro, Nano Banana Edit, GPT Image 2, Flux 2, or Seedream. - Use Case: Generate a batch of four vertical 9:16 social thumbnails at 0.5K resolution for ideation, then promote the winner to a 2K final render with a locked seed. ## Quick Start Ask the agent to generate an image with Nano Banana 2, for example: "Use nano banana 2 to generate a 16:9 product card image of a ceramic mug with the headline 'Brewed Quietly'."

FAQPage Schema
How do I generate images with Nano Banana 2 on RunComfy?▼

Install the RunComfy CLI with npm i -g @runcomfy/cli, authenticate via runcomfy login, then run `runcomfy run google/nano-banana-2/text-to-image` with a JSON input containing your prompt and an output directory.

Nano Banana 2 vs Nano Banana Pro: which should I use?▼

Nano Banana 2 is the flash-tier model suited for rapid drafts, batch variants, and in-image typography. Nano Banana Pro is preferred for hyperrealistic portraits and maximum detail; if unspecified, default to Pro for portraits and 2 for everything else.

What aspect ratios and resolutions does Nano Banana 2 support?▼

It supports 11 aspect ratios including 16:9, 9:16, 1:1, 4:5, and 21:9, plus an auto mode. Resolutions are 0.5K, 1K, 2K, and 4K; values outside these tiers return a 422 error.

How do I render text inside generated images reliably?▼

Quote the exact characters in the prompt, such as "the label reads 'AURA' in clean bold sans-serif", and specify placement and font style. Unquoted text requests produce unpredictable rendering.

Can Nano Banana 2 edit existing images?▼

No, this endpoint is text-to-image only. For image edits that preserve a subject while changing the background or details, use the sibling nano-banana-edit skill and its /edit endpoint.

When should I enable web search for image generation?▼

Enable enable_web_search only when the prompt references current events or real entities, since it adds latency and cost. It is off by default and unnecessary for generic creative prompts.
