Meta Platforms Inc.Open-sourcing Muse Spark 1.2 and rolling out Glimmer AI model on-device could boost adoption and compete with rivals.

Mark Zuckerberg’s recent manifesto promises free or affordable AI tools for billions, but a closer reading reveals a dynamic auction mechanism for users who want to pay for more compute. In the post, Zuckerberg states that those willing to pay will participate in a bidding system designed to offer the lowest possible price while allocating finite compute resources to the most valued uses. He recently announced Meta will be open-sourcing its Muse Spark 1.2 model, and the company also rolled out the open-weight Muse Glimmer AI model that can run on devices like laptops. Neil Shah of Counterpoint Research views this as a way for Meta to fill demand for non-Chinese open models, while Glimmer’s on-device capability could bypass cloud compute costs to compete with Google and Microsoft. Meta’s Q2 2026 costs jumped 55% to $42 billion, and its annual AI spend is estimated at around $130 billion, though its stock rebounded to about $600 after the manifesto and Glimmer news.
