Nano Banana 2 Lite is Google DeepMind's Gemini 3.1 Flash-Lite Image: the speed tier of the Nano Banana family, generating 1K images in about four seconds and editing existing ones from a plain-language prompt. You call Nano Banana 2 Lite through reApi's unified API at a low flat rate per image.
Describe subject, scene, style and composition; for edits, say what changes and what stays.

Nano Banana 2 Lite is the speed-focused member of Google's Nano Banana image family, exposed on reAPI as one async endpoint for both text-to-image and prompt-based editing with up to 10 reference images. Prompts run up to 20,000 characters across 15 aspect ratio options including auto, and every request returns exactly one 1K image — there is no image count and no resolution control — billed per image.
Real-world workflows and production use cases you can build and ship with this model.
Nano Banana 2 Lite is built for product surfaces where users wait on the result: design canvases, story tools, agent-built slides and landing pages. At about four seconds per 1K image, Nano Banana 2 Lite keeps the loop interactive — a user tweaks the prompt, the draft updates, no spinner fatigue. The hero draft on the left is raw Nano Banana 2 Lite output from a single prompt.
Draft one in the playground
Pass up to 10 input images and tell Nano Banana 2 Lite what to change: replace a background, remove an object, restyle a room, adjust the light. This reading nook was generated by Nano Banana 2 Lite, then re-submitted with one instruction — "make it a rainy evening, keep the furniture unchanged" — and the model preserved the chair, plant and framing while rewriting the mood.
When image generation is a per-request product action — e-commerce lifestyle scenes, thumbnails, social cards, personalized postcards — the per-image rate decides whether the feature is viable. Nano Banana 2 Lite bills one low flat rate per image, so batching hundreds of product-scene drafts through Nano Banana 2 Lite stays affordable, with in-image label text that comes back legible.
Speed is the headline. Google positions Nano Banana 2 Lite text-to-image at roughly the four-second mark for a 1K image — several times faster than Nano Banana 2 in published comparisons. For prompt testing, interactive tools and user-facing generation, Nano Banana 2 Lite is the family's responsive option.
Nano Banana 2 Lite bills per generated image — one flat rate whether you generate from text or edit with references, at half of Nano Banana 2's official list rate. Frequent, repeated generation is exactly what Nano Banana 2 Lite is priced for.
There is no separate edit endpoint: send image_urls alongside the prompt and Nano Banana 2 Lite switches to editing, keeping characters and composition consistent while it applies your instruction. One schema, both modalities, the same request to /api/v1/images/generations.
Same family, different jobs: Nano Banana 2 Lite is the speed-and-volume tier; Nano Banana 2 is the full-capability model. Here is how they split, using Google's published specs and independent arena data.
Comparison reflects publicly documented behavior and independent benchmark data at the time of writing (July 2026). Both models are available on reApi; specifications may change as Google updates the family.

OpenPOST to /api/v1/images/generations with model: nano-banana-2-lite, a prompt, and optionally image_urls and an aspect_ratio. Nano Banana 2 Lite returns a task_id immediately.
OpenGET /api/v1/tasks/:id until status is completed — with Nano Banana 2 Lite that is typically seconds, not minutes. The image URL arrives in output.image_urls.
