Zuckerberg says AI is for everyone. Meta’s model is open — and the lockbox stays closed

Meta dropped Glimmer this week, an open-weight AI model anyone can download and run on their own hardware. It sits next to Muse Spark, the company’s bigger model that stays locked behind Meta’s own APIs. Two models, two different doors.

Zuckerberg wrote a letter alongside the release arguing that AI shouldn’t be controlled by a handful of labs. The open weights let anyone — researchers, shops, developers — grab the model and put it to work. But the bigger, more capable systems stay inside Meta. The company is practicing open weights without open power.

Why this matters for us: Meta’s framing puts AI on the side of the commons, but the real compute stays behind their walls. If open-source is going to actually help la comunidad — and not just look good — it has to be the good stuff, not the scraps. We’re watching to see who gets the good models and who gets the press release.
