Google launches Nano Banana 2 Lite for fast, low-cost enterprise image generation

Google is upgrading its AI image generation capabilities with the debut of Nano Banana 2 (NB2) Lite, an optimized model built for rapid execution and tight infrastructure budgets. Technically designated as Gemini 3.1 Flash-Lite Image on Google's application programming interface (API), NB2 Lite is positioned as the fastest and most cost-effective option within Google's creative model family, capable of generating images in 4 seconds at a flat rate of $0.034 per 1,000 images. It's available immediately to enterprise developers through Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform (GEAP).

It's not quite as fast or customizable as startup Krea's new, partially open licensed Krea 2 Turbo, but the big selling point here is the low price and bundling with Google's larger Workplace and AI offerings. This release lands alongside the public preview of Gemini Omni Flash, a multimodal conversational video generation and editing model. However, while Omni Flash represents Google's long-term bet on agentic video manipulation, Nano Banana 2 Lite is the immediate infrastructure workhorse, tailored specifically for high-throughput commercial application, rapid programmatic prototyping, and automated asset generation workflows.

The technology of speed At its core, Nano Banana 2 Lite is built directly upon the Gemini 3.1 Flash Lite architecture, engineered to solve the persistent tension between computational latency and operational overhead. In high-velocity enterprise frameworks, traditional large-scale image models introduce significant friction due to multi-second processing delays and high per-token costs. Google's new lightweight model circumvents these bottlenecks by generating a standard 1k resolution image in under four seconds.

This represents a stark performance optimization over its legacy predecessor, Nano Banana (Gemini 2.5 Flash Image), achieved through targeted enhancements in core baseline capabilities. According to internal documentation, the model features upgraded world knowledge for drafting rough data visualizations and contextual layouts, enhanced character consistency to preserve identity across continuous image streams, and localized typographic rendering capabilities. The trade-offs inherent to this "Lite" designation are transparently outlined in Google’s technical data sheets.

Unlike the broader standard Nano Banana 2 (NB2) and Nano Banana Pro (NB Pro) lines, which support versatile multi-resolution scaling across 1k, 2k, and 4k outputs, Nano Banana 2 Lite restricts its resolution support exclusively to a 1k canvas. Yet, within this specialized operational boundary, the architectural tuning yields surprising competitive efficiencies. In standardized internal benchmarks, Nano Banana 2 Lite achieved a Text to Image arena Elo score of 1251.
