Gemini Omni 1.2 Flash goes GA: 15-second clips, 30% cheaper, and edit-by-chat instead of re-rolling
Google made Gemini Omni 1.2 Flash generally available on Nov 5 across the Gemini API, Google Cloud, Flow, Google Vids, Ads, AI Studio and the Gemini app. Per Google, clips go up to 15 seconds (from 10), API price drops about 30% to $0.07/s at 720p, and you can refine a clip in conversation instead of regenerating from scratch.
What changed, per Google's posts. Native generate and edit length is 3–15 seconds in one-second steps, up from a 10-second ceiling on Omni 1.1. Draft at 360p or 720p, then upscale keepers to 1080p or 4K. Reference stacks can mix character/product/style images, short motion clips (up to about three seconds) and audio cues; Google says faces, garments, packaging type and brand colors hold better across camera moves. Speech and multi-speaker conditioning are called out as stronger, with clearer lip-sync. Multi-turn edits let you swap a product, change lighting or nudge the camera without starting over. Outputs carry a SynthID watermark. Audio references are allowlist-gated on Cloud.
Where it runs today. Google's own thread lists Google Cloud, Flow, Google Vids, Google Ads, AI Studio and the Gemini API, with Gemini app access for Google AI subscribers and 15-second clips on Ultra. Google Vids is offering up to three free 15-second generations per month for anyone with a Google account or Workspace. The cookbook model id is gemini-omni-1.2-flash via the Interactions API (google-genai).
Signals. Official @Google and @GoogleAI posts went up this afternoon (the main @Google post sat near 2.2k likes / 288k impressions within hours). Curators @RoundtableSpace and @Saboo_Shubham_ amplified the same drop. That is official announcement plus curator coverage inside the same day, so we flag it hot.
Our take: for product spins, try-ons and social spots that need a full 15-second beat in one generation, this is the Google-stack default to try next to Kling 4.0 Flash and Seedance 2.5. Price and conversational edit matter more than the extra five seconds alone. We have not run our own side-by-side; consistency and lip-sync claims are Google's and their design-partner quotes (Artlist, FLORA, invideo, Krea, Picsart, Photoroom, QuickFrame, Runway).
