Google released Nano Banana 2 Lite (formally Gemini 3.1 Flash Lite Image), its fastest and lowest-cost image generation model, alongside API availability of Gemini Omni Flash, a multimodal video model producing 720p clips with synchronized audio. The two models are designed to work together in a pipeline: generate images cheaply with Nano Banana 2 Lite, then animate the best result via Gemini Omni Flash. Gemini Omni Flash leads Arena.ai's video generation Elo board at 1,527, while Nano Banana 2 Lite ranks fifth on the image board; pricing is $0.034 per image and $0.10 per second of video respectively.
Google released Gemini 3.1 Flash Image (internally codenamed Nano Banana 2), a successor to Nano Banana Pro that is approximately four times faster and half the cost per image. The system is built on a mixture-of-experts transformer based on Gemini 3 Flash and supports up to 4096x4096 resolution, multilingual text rendering, and character consistency across images. It leads the Arena.ai text-to-image leaderboard by human preference (1,280 Elo) and competes closely with OpenAI's GPT Image 1.5 across multiple leaderboards, positioning Google competitively in the rapidly escalating image generation market.
