Gemini Omni Flash enters Public Preview, Nano Banana 2 Lite gains speed

Google launches Gemini Omni Flash in Public Preview and Nano Banana 2 Lite to speed up multimodal video generation and low-cost image creation.

Two models are joining the Gemini ecosystem, designed to work in tandem. Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image) prioritizes speed and volume: it produces an image in less than four seconds, at an announced cost of $0.034 per 1K image. Google claims it is the fastest and most economical member of the Nano Banana family and recommends it as a replacement for the first version (Gemini 2.5 Flash Image). According to the announcement, it maintains character consistency and legible rendering of integrated text despite the emphasis on throughput. Access is available via Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform, before a gradual rollout to consumer surfaces such as Search, the Gemini app, NotebookLM, Google Photos, and Flow.

Gemini Omni Flash, meanwhile, is entering Public Preview after an initial appearance at Google I/O. This natively multimodal model handles video generation and conversational editing from text, images, and videos. Its pricing is set at $0.10 per second of video, which Google states is the same rate as Veo 3.1 Fast. Sequences are currently capped at ten seconds, with longer durations planned.

The main interest lies in the sequence: an image from Nano Banana 2 Lite serves as a reference for Omni Flash to be set in motion. The Interactions API retains session history and allows up to three successive edits. Generated content includes the SynthID watermark.
