Microsoft Adds Free AI Video Generation to Bing, Powered by OpenAI’s Sora

Microsoft has launched Bing Video Creator, a new AI-powered tool that transforms text prompts into short videos. The tool, powered by OpenAI’s Sora, is free for users globally (except China and Russia) and builds on Bing’s earlier image generation capabilities. It aims to make video creation accessible to anyone.

The feature is rolling out first through the Bing Mobile App and will soon be available on desktop and within Copilot Search. Users can type prompts in the search bar or access the tool via the app’s menu. The generated videos are five seconds long in a 9:16 aspect ratio, and up to three videos can be queued at a time.

Microsoft offers ten free “Fast” generations per user, after which users can continue at standard speed or redeem Microsoft Rewards points for additional fast generations. Completed videos can be downloaded, shared, or linked, and will be stored for 90 days.

Microsoft has integrated safeguards to prevent harmful content generation, combining OpenAI’s Sora protections with its Responsible AI systems. All videos are tagged with content credentials and provenance data under the C2PA standard to indicate they are AI-generated.

Bing Video Creator reflects Microsoft’s ongoing push to integrate generative AI into search and creative tools. “We believe creativity should be effortless and accessible,” the company said.

At Google I/O 2025, the company unveiled Veo 3, a video generation model that not only produces high-quality visuals but also adds realistic audio, a feature not yet seen in rival tools like OpenAI’s Sora. Veo 3 impressed users with its ability to replicate real-world physics, accurate lip-syncing, and creative storytelling. However, Veo 3 can be accessed only by paid users.

Microsoft, with its free tier for the masses, could be looking to attract users' attention to rival Google’s offering. It remains to be seen how people start using it.
