Microsoft has officially rolled out a new AI-powered video generation tool called Bing Video Creator, making it the first platform to publicly deploy OpenAI’s Sora model for free.
The launch, announced Monday, marks a significant milestone in the race to democratize generative video technology and underscores Microsoft’s deepening partnership with OpenAI.
Sora — unveiled in February 2024 — is OpenAI’s most advanced text-to-video model to date. It stunned the tech world with its ability to produce highly coherent, realistic videos from short-written prompts. In internal demos, it generated scenes like a bustling Tokyo street, a coral reef, and a woman walking through the snow — all from plain text inputs. Until now, however, public access to the tool was limited to a small group of vetted researchers and commercial partners under strict usage guidelines.
Free, but Limited Access Through Bing App
Through Bing Video Creator, Microsoft is offering ordinary users their first chance to experiment with Sora — albeit in a heavily restricted format. The tool is currently exclusive to the Bing mobile app, with no desktop access at launch.
Users logged into a Microsoft account can generate up to 10 videos for free. After that, each video generation costs 100 Microsoft Rewards points, a loyalty currency that can be earned by using Bing Search or shopping in the Microsoft Store. For instance, users receive 5 points per desktop Bing search, up to 150 points per day.
Each video is capped at five seconds, and users can only queue up three generations at a time. Output is limited to a vertical 9:16 aspect ratio, designed for platforms like TikTok, Instagram Reels, and YouTube Shorts. Microsoft said it will soon support horizontal aspect ratios, likely in response to growing interest in AI-generated video for broader creative and cinematic uses.
Despite a “fast mode” setting promising shorter wait times, some users report waiting hours for video generation to complete, indicating either a capacity bottleneck or deliberate throttling by Microsoft to manage demand.
Microsoft Bets on Sora to Compete in the AI Ecosystem
Microsoft is both expanding access to cutting-edge AI and pushing aggressively into markets dominated by Google and YouTube by integrating Sora into its search app. While Microsoft’s Bing still holds under 5% of the global search engine market, its integration of generative AI tools — including GPT-4.5, DALL·E image generation, and now Sora — positions Bing as a feature-rich alternative to Google Search.
This strategic deployment also strengthens Microsoft’s commercial relationship with OpenAI. Microsoft has invested over $13 billion into OpenAI since 2019 and currently holds an exclusive license to commercialize its models via Azure. Sora’s deployment on Bing represents the first time the public has been able to use it without direct payment or institutional access.
Ethical Concerns and Impact on Creative Industry
Sora’s capabilities have sparked debate within the creative industry and among policymakers. While praised for its potential to revolutionize filmmaking, education, advertising, and gaming, Sora has also raised alarm over deepfake risks, misinformation, and potential job displacement for editors, animators, and video producers.
OpenAI has acknowledged these risks, saying it will implement “guardrails” and develop tools for provenance and watermarking. Microsoft appears to be following suit by limiting video length, scope, and access — at least in this early phase.
Microsoft’s move comes amid rising competition. Google’s own AI video model, Lumiere, which was unveiled in January 2024, remains in research preview. Meta is reportedly working on an AI video model internally but has not made it public. Unlike Microsoft, both tech giants have so far chosen to keep such tools behind closed doors, citing ethical concerns and platform safety.
By contrast, Microsoft is betting that controlled public rollout — paired with reward-based engagement — could help it leapfrog rivals and generate buzz ahead of broader monetization.
While Bing Video Creator is still in its infancy, Microsoft’s decision to launch Sora in this format signals a long-term vision for making high-quality AI video creation accessible to everyday users. If generation speeds improve and output options expand, the tool could evolve from a novelty into a widely used feature across social platforms and personal projects.
