Mark Zuckerberg stated in a September 25 interview that Meta's personal AI Agent, Muse, had reached millions of users within two weeks of its launch, with its early reception described as a "home run out of the gate." He also announced that Muse would be integrated into the full line of Ray-Ban smart glasses, allowing users to customize wake words to directly summon their personal AI Agent. Zuckerberg further revealed that Meta is building a 5-gigawatt-class training cluster, believing that sufficiently large computing power can "brute force" AGI, and admitted that the failure of Llama 4 was "the scariest moment."
