[Strengths] It performs fast, low-cost instruction-based editing across up to 14 input images. [Best For] Highly recommended for: high-volume edits, quick style transforms, and batch background or attribute changes where cost and throughput matter. [Limitations] Do NOT use this model when you need the highest edit fidelity or richest detail; use Nano Banana 2 Edit or Nano Banana Pro Edit instead. [Routing] Choose the Lite variant for cost- and throughput-sensitive edits; step up to Nano Banana 2 Edit for higher quality. ## OpenAPI ````yaml /model-api/google/google-i2i.json post /google/nano-banana-2-lite-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-lite-edit: post: summary: Nano Banana 2 Lite Edit description: >- [Core Function] Nano Banana 2 Lite Edit (Gemini 3.1 Flash Lite Image) is the lightweight, cost-efficient image editing model of the Nano Banana 2 family; it transforms one or more input images per a text instruction.
