谷歌发布4秒图像模型Nano Banana 2 Lite及Gemini Omni Flash

Google released Nano Banana 2 Lite, a 4-second image model, alongside Gemini Omni Flash.

Image generation usually breaks creative work because every trial costs time, money, and attention.

The lighter image model lowers that friction with 4-second outputs at $0.034 per 1K-resolution image.

Chaining both models is the real product shape, not either model alone.

Nano Banana 2 Lite makes reference images, then Gemini Omni Flash animates them.

Google positions it as the replacement for gemini-2.5-flash-image across high-volume developer pipelines.

Users still need prompt adherence, stable characters, and readable text during fast visual testing.

Gemini Omni Flash extends the workflow from image drafts to editable 10-second video outputs.

It accepts text, image, and video inputs, then edits clips through conversation.

Pricing: $0.10 per second of video output, matching Veo 3.1 Fast.

Gemini Omni Flash currently generates 10-second clips and lacks API audio reference support.

Google says the API accepts video references up to 3 seconds, but Gemini Omni Flash does not process them correctly yet.”

Interactions API keeps session context, so users can stack 3 sequential edits.
