- Glimmer was released this week by Meta as an open-weight AI model that anyone can download and run on their own hardware.
- Muse Spark is Meta’s more powerful model, but it remains locked behind the company’s own APIs.
- Mark Zuckerberg published a 6,500-word manifesto arguing that AI should be “for everyone” rather than controlled by a handful of laboratories.
- Equity hosts Kirsten Korosec, Anthony Ha, and Rebecca Bellan examined Glimmer and Zuckerberg’s manifesto, characterizing his open-access vision as carrying “some asterisks.”
Why it matters: For the two models discussed, people who want to run AI locally can download Glimmer, while those seeking Meta’s more powerful Muse Spark must use its APIs. That split gives local users access to one model, but leaves Meta controlling the more powerful option, making Zuckerberg’s “for everyone” promise narrower in practice than his letter suggests.
