OpenAI has officially announced its investment in Merge Labs, a pioneering brain-computer interface (BCI) startup that counts OpenAI CEO Sam Altman among its co-founders in a personal capacity. This strategic investment was part of Merge Labs' successful seed funding round, which raised $252 million, with OpenAI emerging as the largest investor. The round valued the nascent company at $850 million. Merge Labs' mission is to bridge biological and artificial intelligence, aiming to develop high-bandwidth brain-computer interfaces that maximize human ability and experience. Crucially, the startup is distinguishing itself by focusing on fundamentally new, non-invasive approaches to BCI technology, potentially utilizing ultrasound-based modalities and molecular techniques to interface with the brain without requiring surgical implants. This contrasts with the more invasive electrode-based methods explored by competitors like Elon Musk's Neuralink. OpenAI views BCIs as a critical new frontier for human interaction with AI, believing they will create a more natural and human-centered way to communicate, learn, and engage with technology. The company plans to collaborate with Merge Labs on scientific foundation models and other frontier tools to accelerate research and development. Sam Altman, while a co-founder, will not be involved in the day-to-day operations of Merge Labs. This significant investment is seen as a move that intensifies the ongoing rivalry between Sam Altman and Elon Musk in the realm of advanced technology.
