Nano Banana Lite (Gemini 3.1 Flash-Lite Image) Reaches General Availability
Gemini CLIGoogle moved gemini-3.1-flash-lite-image ("Nano Banana Lite") to general availability, positioning it as the fastest and cheapest model in the Nano Banana image family. It generates an image in about 4 seconds at $0.034 per 1,000 images, trading multi-resolution output (it's capped at 1K) for ultra-low latency and cost. The model is aimed at high-volume, budget-sensitive image generation and editing workloads, and is designed to pair with Gemini Omni Flash: generate a still cheaply with Nano Banana Lite, then animate it with Omni Flash.
Key Takeaways
- 4-second generation time at $0.034 per 1,000 images makes Nano Banana Lite the cheapest, fastest model in Google's image-generation lineup to date.
- The model is capped at 1K resolution, a deliberate tradeoff: 2K and 4K remain exclusive to the standard Nano Banana 2 and Pro tiers.
- Google explicitly designed Nano Banana Lite to pair with Gemini Omni Flash, enabling a cheap-still-then-animate workflow for image-to-video pipelines.
- Despite the speed focus, Google claims no meaningful quality regression in prompt adherence, character consistency, or in-image text rendering.
- Availability spans both developer surfaces (Gemini API, AI Studio, Gemini Enterprise Agent Platform) and consumer products (Search AI Mode, Gemini app, NotebookLM, Photos), signaling Google is pushing this model broadly and quickly.
- Independent coverage (VentureBeat, TechCrunch) frames this release as part of a broader industry push toward cheaper, faster generative media for high-volume enterprise use cases, not just flagship quality wins.

The Fastest, Cheapest Model in the Nano Banana Family
Alongside Gemini Omni Flash, Google shipped gemini-3.1-flash-lite-image to general availability on June 30, 2026, under the consumer-facing name Nano Banana Lite (technically "Nano Banana 2 Lite"). It joins the broader Nano Banana image-generation lineup as the option purpose-built for speed and cost rather than maximum fidelity.
What Changed
Nano Banana Lite generates an image in roughly four seconds, at a flat rate of $0.034 per 1,000 images, a meaningful drop compared to the standard Nano Banana 2 and Nano Banana Pro tiers. The tradeoff is resolution: while the broader Nano Banana line supports 1K, 2K, and 4K outputs, Lite is restricted to a 1K canvas only. Despite the speed-first design, Google says the model still delivers reliable prompt-following, consistent character rendering, and readable in-image text.
Why It Matters for Developers
Nano Banana Lite is designed to slot into higher-volume, latency-sensitive pipelines: cases where teams previously had to choose between quality and throughput. It's also explicitly built to pair with Gemini Omni Flash: generate a still image cheaply with Nano Banana Lite, then hand that image to Omni Flash to animate it into a short video clip, letting teams build image-to-video pipelines without paying full-resolution image costs at every step.
Availability
Nano Banana Lite is immediately available to developers through the Gemini API, Google AI Studio, and the Gemini Enterprise Agent Platform. It's also rolling out across consumer-facing Google surfaces such as AI Mode in Search, the Gemini app, NotebookLM, Google Photos, and Google Flow, though those consumer integrations are a secondary detail for developers building against the API directly.
