Google shipped two generative media models Tuesday: Nano Banana 2 Lite for fast image generation, and Gemini Omni Flash for video and conversational editing. Both landed via the developer blog, available now in Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform.
Nano Banana 2 Lite, technically Gemini 3.1 Flash-Lite Image, is pitched as the cheapest and fastest model in the Nano Banana line. Google claims roughly 4 seconds per image at $0.034 per 1,000 images, undercutting the older NB1 at $0.039 and standard NB2 at $0.067. The catch: it's capped at 1k resolution, while the bigger models scale to 4k. Internal notes peg it at 60 to 70 percent of NB2's general capability, so the speed comes with a quality tradeoff Google itself flags.
Omni Flash handles video from text, image, and video inputs, with editing through natural language. Pricing matches Veo 3.1 Fast at $0.10 per second of 720p output, per Google's own framing.
The pitch is chaining them. Generate an image with Nano Banana 2 Lite, pass it to Omni Flash as a reference, then animate. The Interactions API keeps session history for up to three sequential edits. Limits remain: clips run up to 10 seconds, and audio references plus scene extension aren't supported in the API yet. Both models carry SynthID watermarks. NotebookLM's Short Video Overviews, built on Nano Banana 2 Lite, arrive in the coming weeks.
Bottom Line
Nano Banana 2 Lite generates 1k images in about 4 seconds at $0.034 per 1,000, but Google rates it at 60 to 70 percent of full NB2 capability.
