Zuckerberg Criticizes Closed-Door AI Rivals as Meta Reboots Open Model Releases
Meta's CEO Mark Zuckerberg recently criticized rival companies like OpenAI and Anthropic for their closed-door approach to AI development. In an interview, he argued that this approach risks concentrating too much power in too few hands.
Zuckerberg made his comments as Meta is returning to its open-source model releases after a brief detour into proprietary territory. This move comes after the release of Muse Spark in April 2026, which was seen as an attempt by Meta to play catch-up with competitors working behind closed doors.
The Llama series, on which Meta built its AI reputation, has been openly released for developers and researchers to use, modify, and build upon. However, the earlier Llama models received a somewhat underwhelming reception relative to the frontier capabilities being demonstrated by competitors.
Zuckerberg framed openness as an extension of American values, contrasting it with what he characterized as a doom-focused mentality at rival labs that use safety concerns to justify keeping their most powerful models locked down. He is not fighting this battle alone, as Microsoft, Nvidia, and Google have shown varying degrees of alignment with Meta's open approach.
