Gemini Omni 1.2 Flash adds 15-second AI video and cuts generation cost by 30%

Google's Gemini Omni 1.2 Flash now produces AI video clips of up to 15 seconds and does so at 30% lower generation cost, according to a Techgenyz report. The update is framed around duration and unit economics rather than a new model name, and both numbers speak to the same question: what it takes for generated video to move from demo to production.

Fifteen seconds is not a cosmetic figure in video generation, because duration is what decides use case. A few seconds of footage works as a motion demo; fifteen seconds is close to the standard length of a vertical short, long enough for a complete action sequence or a single narrative beat. That is why clip length keeps showing up in model marketing.

The 30% cost cut matters just as much. Video generation is compute-heavy, and a ten-second clip often needs several sampling passes and retries, so per-clip cost determines whether the capability can sit inside high-volume workflows such as ad creative, product pages and social content. If the price stays high, a longer clip is still a demo.

The report itself is thin. Neither the headline nor the summary states resolution, frame rate, whether audio is included, which regions have access, how billing is measured, or when the capability ships. On the available evidence this reads as a metric disclosure rather than a full launch note.

It is still worth recording, because the competitive focus in video models is shifting from whether generation works to what a generation costs. Perceived gains in image quality are getting harder to distinguish, while cost, duration and consistency are what actually decide procurement. A Flash-tier model moving on duration and price at once says Google is pushing video deeper into its product line.

Three things to watch: whether independent tests confirm that 15-second clips hold together in motion and subject consistency, whether the 30% figure is measured per clip or per second, and whether the capability reaches developer-facing channels. Until then, the headline numbers describe a direction, not an experience.
