[Strengths] It edits up to 14 reference images, or one HTTPS video plus up to 10 images, at 1K, 2K, or 4K, with improved character and multi-reference consistency. thinkingLevel defaults to medium. Optional systemInstruction is omitted when blank. enableWebSearch turns on Google Search grounding (web and image search) only when true. [Best For] Prompted restyling, multi-image product and character edits, and turning a video into a still. [Limitations] Do NOT use this model for text-only generation, 512-pixel output, or audio generation. At least one of image or video is required. seed, temperature, topP, topK, and logprobs are rejected. [Routing] Use this endpoint when the user provides images or a video and wants Nano Banana 2.1. Use google/nano-banana-2-edit for the previous Gemini 3.1 Flash Image editor, including 512 output. Use google/nano-banana-2.1 when there is no visual input. Use google/nano-banana-pro-edit for the highest-fidelity still edits that do not need video input. ## OpenAPI ````yaml /media-model-api/google/google-i2i.json post /google/nano-banana-2.1-edit openapi: 3.1.0 info: description: The image-to-image models API from Google. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Google Image-to-Image Models API servers: - url: https://api.modellix.ai/api/v1 description: The image-to-image models API from Google. security: - bearerAuth: [] paths: /google/nano-banana-2.1-edit: post: summary: Nano Banana 2.1 Edit description: >- [Core Function] Nano Banana 2.1 Edit is Google's fast image-editing and video-to-image model, exposed as google/nano-banana-2.1-edit.
