Who owns Whisper AI?

OpenAI publishes Whisper, so OpenAI is the company behind it. Whisper is not a separate company, and it is released as a model rather than as a finished product. Within OpenAI, a nonprofit foundation controls the for-profit company that now carries the commercial work. Because Whisper's code is released under the MIT License, anyone can use, copy or change it, whatever OpenAI decides about its own products.

OpenAI publishes Whisper, and its repository sits under OpenAI's name

Whisper's code is in OpenAI's repository on GitHub, and the repository carries the MIT License for the code and model weights ¹. OpenAI released the model in September 2022 ². The paper that introduced the model lists six authors, including Greg Brockman and Ilya Sutskever ³.

Authorship of a paper is not the same as ownership of a product. The author list tells you who wrote the research. OpenAI is the publisher of the model. A reader who wants the legal detail should read the license and OpenAI's terms rather than rely on a summary here.

OpenAI's nonprofit foundation controls the for-profit company

In October 2025, OpenAI completed a recapitalization. Its nonprofit is now the OpenAI Foundation, and it retains control of the for-profit entity, now called OpenAI Group PBC ⁴. The foundation's stake was valued at about $130 billion at the time ⁵.

The sources we checked do not say which legal entity publishes Whisper's code, so this page treats the restructuring as describing the company behind Whisper, not a separate owner of the model.

Microsoft holds a large minority stake in the for-profit company

In the same restructuring, Microsoft's investment in OpenAI Group PBC represented roughly 27 percent ownership, on an as-converted diluted basis ⁶. That is a minority stake, not control. Ownership and control are separate questions, and the sources do not tie the foundation's control to a fixed percentage.

Ownership percentages change over time as the company raises money, so check the latest filings or OpenAI's own pages before you quote a figure.

The chief executive was removed by the board and then reinstated

OpenAI's chief executive, Sam Altman, was fired by the board and later reinstated after board members questioned his leadership ⁷. The episode shows that OpenAI's board has the power to remove its chief executive.

Leadership can change, so confirm the current chief executive on OpenAI's own website before you rely on it.

Whisper is not a product with its own owner, but other apps use its name

Because the model is open source, many companies and developers build products on it. Their names are their own. The App Store listing for Whisper AI Keyboard describes a voice-to-text keyboard extension ⁸. When an app uses the word "Whisper," read its developer name before you assume OpenAI made it.

Our answer on whether there is an official Whisper app lists the apps by platform, and whether Whisper is free explains what the open license covers and what it does not.

What to do: check the publisher, the license and the product separately

1. For the model, check the repository and its license. The code is public, and the license decides what you may do with it.
2. For a product, check the developer named on its store page or website, not the model's name.
3. For questions about OpenAI's governance, read OpenAI's own announcements and filings, and treat news summaries as a second source.
4. For a dictation app built on speech models, Yap, which we make, is an on-device app for Mac and Windows. Read our overview of Whisper for how the model fits into dictation, and how it compares with Wispr Flow for a second product.
