Zuckerberg argues that 'open weight' models, the publicly released kind anyone can run, are how America keeps up with Chinese rivals like DeepSeek and Moonshot.
Meta released a new open-weight model called Muse Glimmer on Monday and used the launch to lobby Washington. The product is small enough to run on a Mac or a PC with a single consumer graphics card. The policy ask is the news.
"Open-weight" means the model's core components are released publicly, so anyone can download, run, or customize them. It is the opposite of the closed systems from OpenAI, Anthropic, and Google. Meta is pitching this cheaper, customizable track as the lane where American labs are losing ground.
Zuckerberg named the rivals. In his statement, carried by Reuters via aawsat and reflected in Business Insider's same-day coverage, he cited Moonshot's Kimi K3, Alibaba's Qwen3.8-Max, and DeepSeek's V4-Flash, three Chinese open-weight models he said are already matching US frontier systems. He asked US policymakers to lower the regulatory and export barriers on open-source AI so domestic labs can compete.
Hugging Face reportedly used a Chinese open-weight model last month to defend against a cybersecurity attack it described as involving a "rogue" OpenAI model, citing closed-source use restrictions as the reason.
Meta formed a costly "superintelligence team" in 2025 to re-enter the AI race. Shares were up about 1% in Monday premarket trading, down roughly 10% year-to-date. The next few weeks will show whether the policy ask has any follow-through in Washington.
