# Meta Platforms Launches Open-Weight A.I. Model

Meta Platforms (META) has launched a new open-weight artificial intelligence (A.I.) model as it looks to better compete against U.S. and Chinese technology rivals.

The new A.I. model, called “Muse Glimmer,” is smaller than competing products and is designed for agentic tasks that run on a Mac or PC computer with a single graphics card.

Meta said that the new A.I. model is designed for systems that run directly on people’s devices.

Importantly, Meta’s newest A.I. model is open source, or open weight, allowing it to better compete against similar applications from Chinese technology firms.

Open weight refers to artificial intelligence models that are released publicly for anyone to download and use.

Such models are typically cheaper than leading models from so-called frontier labs such as OpenAI and Anthropic that keep their A.I. products closed and charge money to access them.

A debate is raging among U.S. technology companies over whether to make A.I. models open weight or keep them closed.

Meta’s new open-weight model is being launched as the social media giant seeks to strengthen its position in the global A.I. race.

Meta CEO Mark Zuckerberg has thrown his support behind open-weight models that are gaining traction as businesses grow wary of rising A.I. costs and worry about cybersecurity threats.

Chinese startups are leading the global race for open-weight models, with Moonshot’s Kimi K3 and Alibaba’s (BABA) Qwen 3.8-Max delivering performance that rivals top U.S. A.I. models.

Meta’s new A.I. model is also being launched with the company’s stock down 23% over the past year and trading at $592.10 U.S. per share.
