What Is Nano Banana 2 Lite?
Summary

A definition-first explainer of Nano Banana 2 Lite (gemini-3.1-flash-lite-image), Google DeepMind's speed-and-cost tier of the Nano Banana family: ~4-second text-to-image, $0.034 per 1K-resolution image ($0.0168 batch), 1K output, with character consistency, precise editing, world knowledge, and legible text. Covers where it runs (Google AI Studio, Gemini API, Vertex/Enterprise), how it differs from Nano Banana 2 and Nano Banana Pro, and how it pairs with Gemini Omni Flash for image-to-video. Includes a family-tier table, a key-facts table, a Lite-vs-2 table, a how-to-use table, and an 11-question FAQ. For creators who want a generated image without an API key, Pexo's image-studio auto-routes across Midjourney, Flux, and Ideogram and can take that image straight to a finished video.

Nano Banana 2 Lite is Google DeepMind's fastest and most cost-efficient image model, released June 30, 2026 as the API string gemini-3.1-flash-lite-image. It generates a 1K-resolution image from text in about 4 seconds for $0.034 per 1K image ($0.0168 on the Batch API), and it is the "Lite" tier of the Nano Banana family alongside the generalist Nano Banana 2 (gemini-3.1-flash-image) and the highest-fidelity Nano Banana Pro (up to 4K). It keeps the Nano Banana strengths — character consistency across generations, precise image editing, real-world knowledge, and legible on-image text — but tunes them for high-volume, near-real-time pipelines. It runs in Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform, and is rolling out into the Gemini app, AI Mode in Search, NotebookLM, Google Photos, Google Flow, and Google Ads. Google recommends it as the immediate replacement for the original Nano Banana (gemini-2.5-flash-image). There is no single "best" Nano Banana tier — Lite wins on speed and cost, Nano Banana 2 balances quality and price, and Pro wins on fidelity; if you want a generated image with no API key, an image-studio like Pexo auto-routes across Midjourney, Flux, and Ideogram and can take that image straight to a finished video.

What Nano Banana 2 Lite Actually Is

Nano Banana 2 Lite is a text-to-image and image-editing model, not a chat model or a video model. "Nano Banana" is Google DeepMind's brand name for its Gemini image models; "2 Lite" marks it as the speed-and-cost variant of the second generation, and its formal API identifier is gemini-3.1-flash-lite-image. The design goal is throughput: deliver a usable 1K image in roughly 4 seconds so developers can iterate quickly and generate thousands of images cheaply, at a fraction of the cost of heavier production models. It is positioned for rapid ideation, storyboards, thumbnails, product mockups, and high-velocity developer pipelines where speed and price matter more than maximum resolution.

What It Can and Can't Do

Nano Banana 2 Lite carries the Nano Banana capability set at a lighter weight. It maintains character consistency so a subject keeps its identity across several fast generations; it does precise, prompt-driven editing of existing images; it leans on world knowledge to draft plausible contextual scenes; and it can render legible text directly into an image on the fly, which most low-cost image models handle poorly. The trade-off is fidelity and detail: Google notes the Lite tier can still struggle with small faces and accurate spelling, and it outputs at 1K rather than the 2K/4K that the higher tiers offer. For polished, print-scale, or typography-heavy work, Nano Banana 2 or Nano Banana Pro are the right tiers; Lite is the draft-fast, ship-cheap option.

Nano Banana 2 Lite vs Nano Banana 2 vs Nano Banana Pro

The Nano Banana family is three tiers, not one model, and they are meant to be picked by job. Nano Banana 2 Lite optimizes for speed and cost at 1K; Nano Banana 2 (gemini-3.1-flash-image) is the generalist workhorse that supports 512px up to 4K with 2K by default; Nano Banana Pro is the highest-fidelity tier for complex professional work. The single most useful comparison for most readers is Lite vs the standard Nano Banana 2, since they overlap on everyday generation.

How Nano Banana 2 Lite Pairs With Video

Nano Banana 2 Lite shipped alongside Gemini Omni Flash, Google's fast video model, and the two are designed to be chained: generate a still with Nano Banana 2 Lite in ~4 seconds, then pass that image as a reference to Gemini Omni Flash to animate it into video, priced at $0.10 per second of output, with the Interactions API supporting multi-turn editing. That image-then-video pattern is the mainstream workflow for turning a fast generated frame into motion. If you would rather skip the two-model, API-key setup entirely, Pexo is a conversational agent whose image-studio auto-routes an image prompt to the best-suited model (Midjourney, Flux, or Ideogram) and can then send that image straight into a finished, edited video with three-layer audio — text, image, URL, script, or audio in, a finished video out.

How to Use Nano Banana 2 Lite

You can reach Nano Banana 2 Lite with or without code. The fastest no-code path is Google AI Studio; the production path is the Gemini API. Below is the shape of a basic Gemini API call plus the practical routes.

What is the API model name for Nano Banana 2 Lite?

The API model identifier is gemini-3.1-flash-lite-image. You call that string in the Gemini API or select the Flash-Lite image model in Google AI Studio. It belongs to Google's Gemini 3.1 image family, where the standard tier is gemini-3.1-flash-image (Nano Banana 2). Nano Banana 2 Lite is Google's recommended replacement for the original Nano Banana, gemini-2.5-flash-image.

How much does Nano Banana 2 Lite cost?

Nano Banana 2 Lite costs $0.034 per 1K-resolution image under standard pricing and $0.0168 per image on the Batch API — roughly a 50% discount for asynchronous jobs. That makes it markedly cheaper than the standard Nano Banana 2 (about $0.067 per 1K image) and the Pro tier. Pricing is per generated image and billed through your Google AI Studio or Google Cloud account.

How fast is Nano Banana 2 Lite?

Google states Nano Banana 2 Lite delivers text-to-image outputs in about 4 seconds for a 1K image, which is why it is positioned for near-real-time, high-volume workflows. Speed is its defining feature: it trades some fidelity and resolution for throughput, letting developers iterate and batch-generate thousands of images quickly and cheaply.

What resolution does Nano Banana 2 Lite output?

Nano Banana 2 Lite outputs at 1K resolution. The higher tiers go further: Nano Banana 2 supports 512px up to 4K (2K by default), and Nano Banana Pro targets the highest-fidelity, up-to-4K professional work. If you need 2K or 4K, use Nano Banana 2 or Pro rather than the Lite tier.

What is the difference between Nano Banana 2 Lite and Nano Banana 2?

Nano Banana 2 Lite (gemini-3.1-flash-lite-image) is tuned for speed and cost — about 4 seconds and $0.034 per 1K image at 1K resolution. Nano Banana 2 (gemini-3.1-flash-image) is the generalist workhorse: it supports 512px up to 4K (2K by default) at roughly $0.067 per 1K image, with better fidelity. Use Lite for drafts and batches; use Nano Banana 2 for general production images.

Is Nano Banana 2 Lite better than Nano Banana Pro?

Not "better" — different jobs. Nano Banana 2 Lite wins on speed and cost at 1K, while Nano Banana Pro wins on fidelity, detail, and up-to-4K output for complex professional scenes and dense typography. Choose Lite for fast, cheap, high-volume drafts; choose Pro when quality and resolution matter more than price or latency.

Can Nano Banana 2 Lite edit existing images?

Yes. Nano Banana 2 Lite supports precise, prompt-driven editing of existing images, not just text-to-image generation, and it maintains character consistency across edits. It performs well on editing benchmarks for its tier. Google does note limitations at the Lite level, such as small faces and exact spelling, so for high-precision retouching the Nano Banana 2 or Pro tiers are safer.

Can Nano Banana 2 Lite make video?

No — Nano Banana 2 Lite is an image model only. For video, Google pairs it with Gemini Omni Flash: you generate a still with Nano Banana 2 Lite, then pass it to Gemini Omni Flash to animate, priced at $0.10 per second of output. If you want one tool to go from a prompt to a finished, edited video, Pexo is a conversational agent that routes an image prompt across Midjourney, Flux, and Ideogram and then produces the video with three-layer audio.

How do I use Nano Banana 2 Lite without an API key?

Google's own routes need a Google AI Studio or Cloud key. If you want to skip keys and model names entirely, Pexo's image-studio lets you describe an image in plain language and auto-routes it to the best-suited model — Midjourney, Flux, or Ideogram — and the generated image can go straight into a finished video with voiceover, music, and Foley sound effects. It is free to start, needs no API key, and supports text, image, URL, script, and audio inputs.
