Google today announced Nano Banana 2 Lite and preview availability of Gemini Omni Flash as its latest media generation models for developers, as well as NotebookLM users.

Nano Banana 2 Lite (officially known as Gemini 3.1 Flash-Lite Image) is Google’s “fastest and most cost-efficient image generation and editing model.” Entering general availability today, the company touts 4-second image generation.

Compared to the original Nano Banana (Gemini 2.5 Flash Image), this new model offers “fast image generation with a significant leap in visual quality and capability.” Capabilities include:

• World knowledge: Quickly draft accurate contextual scenes, rough data visualizations, and location-specific mockups.
• Character consistency: Maintain character identities and object fidelity across multiple swift generations to easily build out storyboarding tools or embed virtual try-ons for e-commerce.
• Quick text and localization: Draft copy on the fly by rendering legible text directly into rapid generations to see how typography works across localized ad variations.

Meanwhile, Gemini Omni Flash is now in public preview. This follows the Gemini app announcement at I/O:

• Conversational editing: Swap characters, relight scenes, or alter angles using natural language while natively maintaining original audio and video tracks.
• Multimodal input: Combine text, images, and video inputs to guide video generation. Gemini Omni Flash natively generates audio with every video output, while maintaining character, object, and style consistency.
• World knowledge and simulation: It combines an intuitive understanding of physics with Gemini’s knowledge of history, science and cultural context, bridging the gap from photorealism to meaningful storytelling.
• Text and action synchronization: Render legible text and graphics directly into video, syncing kinetic typography and explainer text with on-screen movements.

Gemini Omni Flash pricing matches Veo 3.1 Fast at $0.10 per second of 720p video output.

Both models are now available in Google AI Studio and the Gemini Enterprise Agent Platform.

NotebookLM is using Nano Banana 2 Lite for Short Video Overviews. This new format provides a 60-second portrait video with “narrative explanations and educational animations,” like Cinematic Video Overviews. It will be available in the coming weeks.
