Generate images with Google Nano Banana 2 (Gemini-family flash-tier text-to-image) on RunComfy — bundled with the model's documented prompting patterns so the skill gets sharper output than naive prompting against the same model. Documents Nano Banana 2's strengths (rapid iteration, in-image typography rendering, predictable framing, optional web-grounded context), the resolution-tier pricing, the safety-tolerance dial, and when to route to Nano Banana Pro / GPT Image 2 / Flux 2 / Seedream instead. Calls `runcomfy run google/nano-banana-2/text-to-image` through the local RunComfy CLI. Triggers on "nano banana", "nano-banana-2", "nano banana 2", "google image gen", "gemini image", or any explicit ask to generate with this model.

What this skill does
Nano Banana 2 — Pro Pack on RunComfy runcomfy.com · Model page · GitHub Google Nano Banana 2 — the flash-tier text-to-image model in the Gemini family — hosted on the RunComfy Model API. Optimized for ideation, social-thumbnail batches, and rapid drafts with strong in-image typography. When to pick this model (vs siblings) Nano Banana 2 is the flash-tier of the Google image-gen line. Pick it when iteration speed and predictable framing matter more than maximum detail. You want Use --- --- Rapid drafts, social thumbnails, batch variants Nano Banana 2 In-image typography with predictable rendering Nano Banana 2 Web-grounded image (current events / real entities) Nano Banana 2 + enablewebsearch Image edit (preserve subject, swap background) Nano Banana Edit (sibling skill) Heavy stylization, painterly look Flux 2 Maximum prompt adherence + multilingual text GPT Image 2 2K–4K hero shots, max realism Seedream 5 Hyperrealistic portrait Nano Banana Pro If the user said "Nano Banana" / "nano-banana-2" / "Gemini image" explicitly, route here regardless. If they said "Nano Banana" without specifying 2 vs Pro, default to Pro for portraits and 2 for everything else. Prerequisites 1. RunComfy CLI — npm i -g @runcomfy/cli 2. RunComfy account — runcomfy login opens a browser device-code flow. 3. CI / containers — set RUNCOMFYTOKEN=<token> instead of runcomfy login.
