Alongside that announcement, Meta launched Muse Glimmer, a new family of smaller, open-source models specifically designed to run on laptops and other consumer devices rather than relying entirely on cloud-based data centers. In the essay, Zuckerberg argued that American AI labs face structural disadvantages in the open-source race due to domestic restrictions on training data and other regulatory friction. Analysts also noted a financial dimension to Meta's open-source strategy. The lab had previously released Muse Spark 1.1 in July, which carried Meta's first-ever price tag attached to one of its AI models, alongside Muse Code, a terminal-based coding agent built on Muse Spark 1.2. At the time, Meta positioned its API pricing for Muse Spark 1.1 at roughly 25% of what Anthropic and OpenAI charge for comparable models.
