Gemini Omni 1.2 Flash stretches AI video to 15 seconds with native audio and a 30% price cut

Google's Omni line combines video generation and editing in one model. Version 1.2 Flash, announced through Google AI Studio and amplified by DeepMind, makes three main changes according to The Decoder and the model card:

- Maximum clip length rises to 15 seconds.

- Price falls about 30%, to roughly $0.07 per second of output.

- Users can edit existing footage conversationally, with frame-accurate changes and synchronized native audio.

The "Flash" tier signals Google's usual strategy: push price and speed down so developers build video into products, rather than competing only on top quality. Generating video and audio together in one model avoids the separate dubbing step other pipelines need. Conversational editing makes video creation iterative, closer to how developers already work with text and image models.

Competition is intense. OpenAI just shipped ChatGPT Images 2.6 with faster generation, xAI moved to grok-imagine-image-2.0, and community threads on r/StableDiffusion show hobbyists swapping a character across an hour-long TV episode. At 15 seconds, Omni is still a clip tool, not a scene tool.

Google is also retiring legacy Gemini 2.5 endpoints on December 1. Meanwhile, developers on Hacker News are angry about Google training on paid personal Gemini chats by default. Watch quality comparisons against Sora-class models, and whether the price cut drives real API adoption.
