What AI models does Generate Nanobanana use?

Generate Nanobanana uses Google's Gemini media models through the Gemini API, routing requests to four tiers: Nano Banana 2 Lite for draft images, Nano Banana 2 for standard images, Nano Banana Pro for quality images and multi-image fusion, and Gemini Omni Flash for video generation.

Does Generate Nanobanana require user approval before generating images?

Yes, every paid call is gated behind explicit user approval after showing a quoted price. The skill records whether the user approved each generation in the JSON sidecar file.

What information does Generate Nanobanana record about each generation?

Generate Nanobanana writes a JSON sidecar next to every output that records the exact prompt, model ID, reference images used, response ID, cost, timestamp, and user approval status.

Can I use reference images with Generate Nanobanana?

Yes, you can link or import a folder of reference images (logos, faces, product shots) for reuse across generations. The skill loads real reference images instead of relying on text descriptions alone.

What API key does Generate Nanobanana require?

Generate Nanobanana requires a Google AI Studio API key (GEMINI_API_KEY) and the google-genai Python package to function.

Why it matters

Generate and edit images and videos by routing requests to the appropriate Google Gemini model tier, loading real reference images for brand consistency, gating every paid call behind explicit user approval, and logging complete generation metadata in JSON sidecars.

Outcomes

What it gets done

Route image and video generation requests to the correct Gemini model tier (draft, standard, quality, or video)

Load real reference images from named sets or folders instead of relying on text descriptions for logos, faces, and brand marks

Quote current per-unit pricing and obtain explicit user approval before every billable generation call

Write JSON sidecar logs next to every output recording the exact prompt, model ID, references used, cost, and timestamp

Overview

Generate Nanobanana

Generate Nanobanana offers AI models for visual content creation. Nano Banana 2 balances crisp detail, accurate style adherence, and high speed for production work. Nano Banana Pro delivers highest-quality rendering, complex multi-image fusion, character consistency, and sharp on-image typography. Gemini Omni Flash supports text-to-video, image-to-video, subject-reference video, stateful multi-turn video editing, and editing of uploaded video. Use this skill when you need fast production images (Nano Banana 2), premium rendering with typography or multi-image fusion (Nano Banana Pro), or video generation and editing capabilities (Gemini Omni Flash). Note that Gemini Omni Flash requires explicit user cost approval before each paid run.

What it does

Generate Nanobanana provides access to specialized AI models for visual content creation. Nano Banana 2 delivers fast, production-ready image generation with crisp detail and accurate style adherence. Nano Banana Pro handles highest-quality rendering, complex multi-image fusion, character consistency across images, and sharp on-image typography. Gemini Omni Flash supports text-to-video, image-to-video, subject-reference video, stateful multi-turn video editing, and editing of user-uploaded video.

When to use - and when NOT to

Use Nano Banana 2 when you need fast turnaround on finished production images where speed and quality balance matter. Choose Nano Banana Pro when your project demands the highest rendering quality, requires merging multiple images into complex compositions, needs consistent character appearance across multiple images, or includes text that must be sharp and legible within the image itself. Select Gemini Omni Flash when working with video that requires generation from text descriptions or static images, subject references, multi-turn edits to refine video output across several iterations, or editing of uploaded video files.

Do not use Gemini Omni Flash for quick exploratory work without budget approval, as every paid run requires explicit user cost approval before execution per the skill's cost-approval rule. Do not choose Nano Banana 2 when your project requires the absolute highest quality rendering or complex multi-image fusion, as these capabilities are specific to Nano Banana Pro.

Inputs and outputs

Nano Banana 2 and Nano Banana Pro generate images. For Nano Banana Pro, multiple source images can be used for fusion work and typography requirements can be specified. Gemini Omni Flash supports text-to-video, image-to-video, subject-reference video, stateful multi-turn video editing, and editing of uploaded video files.

Who it's for

Nano Banana 2 fits teams prioritizing production velocity and consistent quality for finished deliverables. Nano Banana Pro targets professionals requiring premium rendering quality, such as those creating marketing materials with embedded text, character-driven visual narratives requiring consistency, or complex composite imagery. Gemini Omni Flash serves those who need to work with video through various generation and editing approaches.

Source README

Nano Banana 2 is the standard production model for image generation. It balances crisp detail, accurate style adherence, and high speed for most finished work.

Nano Banana Pro is the flagship model for highest-quality rendering, complex multi-image fusion, character consistency, and sharp on-image typography.

Gemini Omni Flash generates and edits video. It supports text-to-video, image-to-video, subject-reference video, stateful multi-turn video editing, and editing a user's own uploaded video. Every paid run requires explicit user cost approval before execution - see the skill's cost-approval rule.
