OpenAI acquires Weights.gg team

OpenAI bought Weights.gg, a small startup that built tools for cloning voices, and absorbed its team earlier this year, according to reports published on May 16. The New York Times first reported the deal, citing two people familiar with the acquisition, and The Decoder said the startup’s roughly six-person team is now working across OpenAI. Financial terms were not disclosed in the reports. Weights.gg had already shut down its public service, posting a farewell message to its community on April 1, 2026. ### What, exactly, did OpenAI buy? The New York Times reported on May 15 that OpenAI bought Weights.gg earlier in 2026 and acquired both the company’s intellectual property and its staff. The Decoder, citing the Times, said the startup had about six employees and had raised roughly $4 million in venture capital. Neither OpenAI nor Weights.gg publicly announced a purchase price in the reporting reviewed here. (nytimes.com) Weights.gg ran a consumer-facing platform where users could create and share AI models, including voice-cloning tools. The Decoder described it as a social network for AI algorithms and said users could clone celebrity voices including Taylor Swift and Donald Trump; it also cited online samples featuring Samuel L. Jackson. ### Why was Weights.gg notable before the deal? (nytimes.com) Weights.gg became known for public demos that pushed into celebrity imitation, a category that has drawn scrutiny across the AI industry because the outputs can closely mimic identifiable people. The Decoder reported that the company’s tools let users generate and share voice clones of public figures, and that those demos were part of what made the startup stand out. (the-decoder.com) April 1, 2026, was the date on the goodbye notice cited by The Decoder, marking the end of the startup’s public service. That shutdown came before the acquisition became public. ### Is OpenAI planning to launch a consumer voice-cloning app? The Decoder reported on May 16 that OpenAI does not plan to release a standalone product similar to Weights.gg, citing the same underlying Times reporting. (the-decoder.com) Instead, the team is now working inside OpenAI across different groups. The reporting did not identify which specific OpenAI teams those employees joined. OpenAI has already taken a cautious public line on synthetic voice tools. In a March 2024 post on its website, the company said it was sharing a small-scale preview of Voice Engine, a model that can generate speech resembling a speaker from a 15-second sample, but it stopped short of a broad release because of misuse risks. ### How does this fit with OpenAI’s existing voice work? (the-decoder.com) OpenAI said in its March 2024 post that Voice Engine had been used in limited settings and that synthetic voices carried “serious risks.” The company said at the time that the model could generate natural-sounding speech from a short sample and that it was taking a gradual approach to deployment. The Decoder said OpenAI is building voice capabilities into existing products such as ChatGPT’s voice mode and its developer API rather than preparing a separate cloning service. (openai.com) That reported approach lines up with OpenAI’s earlier decision not to widely release Voice Engine. ### What happens next? OpenAI’s next visible step is likely to show up inside products it already ships, not in a revived Weights.gg service, according to The Decoder’s report. (openai.com) The acquired team is already inside OpenAI, and the public Weights.gg platform has been offline since April 1, 2026. As of May 16, the reported plan was no standalone cloning product and continued work through OpenAI’s existing voice features and developer tools. (the-decoder.com)
