Google launches Gemini Omni, multimodal AI video generator with avatar cloning and physics modeling

Google has released Gemini Omni, a multimodal AI video generation tool that the company positions as doing "for video what Nano Banana did for images." The first tier, Gemini Omni Flash, is now rolling out to the Gemini app, Google Flow, and YouTube Shorts.

Core capabilities

According to Google, Omni accepts four input types: text, images, audio (currently voice recordings only), and video. The company claims the model can "create anything from any input," with plans to expand beyond video generation. The tool incorporates SynthID digital fingerprinting technology to identify AI-generated content.

Avatar cloning feature

Omni includes an Avatars feature that creates digital replicas of users, generating videos that "look and sound like you," according to Google. The company stated it is "still working to test" the capability to edit videos to change audio and speech, citing responsible deployment concerns.

Physics modeling

The model incorporates what Google describes as "an improved intuitive understanding of forces like gravity, kinetic energy, and fluid dynamics." This physics modeling aims to create more realistic motion compared to earlier AI video tools that treated objects like ragdolls rather than physical entities.

Natural language editing

Omni supports conversational video editing through natural language instructions. Google claims that "every instruction builds on the last" while maintaining character consistency and scene continuity. The company said users can "change specific things, or change everything" in existing videos, including adding characters, transforming objects, or altering backgrounds.

Google has not disclosed video resolution limits, supported aspect ratios, maximum clip length, or pricing per plan tier. The company also has not specified whether Omni will integrate with professional editing software like Final Cut, Premiere Pro, or DaVinci Resolve.

Availability

Gemini Omni Flash is rolling out now to enterprise customers through the Gemini app, Google Flow, and YouTube Shorts. Google has not announced whether the web version of Gemini will support Omni or if users must access it through the Flow interface.

What this means

Gemini Omni represents Google's entry into the competitive AI video generation space, directly challenging OpenAI's Sora. The physics modeling and multimodal input capabilities address key weaknesses in earlier AI video tools. However, the lack of disclosed specifications—particularly around resolution, format support, and professional workflow integration—leaves open questions about whether this targets casual creators or professional production environments. The avatar cloning feature introduces significant trust and verification challenges for video content, even with SynthID watermarking.
