Mark Zuckerberg published a letter on August 10 arguing that superintelligence should be open to everyone, not locked inside a few companies or governments. The same day, Meta released the weights for Muse Glimmer, a 30 billion parameter model that runs on a single consumer graphics card. The move lands as crypto projects push decentralized AI networks as an alternative to corporate control.
The letter and the model
Zuckerberg framed open source models as a safeguard against centralization and a force for empowering people. Muse Glimmer, released under Apache 2.0 terms on Hugging Face, has a quantized size under 20 GB, meaning it can run locally on a single consumer GPU. Meta plans to release weights for Muse Spark 1.2, its latest foundation model, soon.
In the letter, Zuckerberg promised that everyone will have an exceptionally capable personal AI agent that understands the user, with free or affordable access. He also mentioned creative tools and a tutor with doctorate-level knowledge as part of Meta's superintelligence vision. He rejected the idea that AI must replace workers faster than it upgrades them, and expects small teams to run large companies using personal agents.
The crypto connection
Crypto projects have pitched decentralized AI networks as a fix for corporate control. Grayscale named Bittensor (TAO) as its preferred exposure in June. Zuckerberg's open-source push echoes that ethos, though Meta remains a centralized player. The difference is who holds the keys: a single company's board or a distributed network of validators.
The cost and the guardrails
Meta guided 2026 capital spending to between $125 billion and $145 billion, and AI spending squeezed second quarter margins. The company also backed a Texas data center venture worth $14 billion. Zuckerberg said Meta's independent board will approve safety criteria for model releases, and he wants governments to inspect intermediate training checkpoints. That's a notable concession, but it still leaves Meta in charge of the process.
The OpenAI split
OpenAI warned about power concentration in April, but the two labs disagree on who should hold the keys to superintelligence. Zuckerberg's letter argues for open access, while OpenAI has kept its models closer to the chest. The tension is real, and it's playing out in public as both companies race toward the same goal.
Meta plans to release Muse Spark 1.2 weights soon. That will be the next test of whether Zuckerberg's open-source promise holds up in practice.
