Meta's New AI Can Run on Your Own Macs, No Cloud Needed

Meta just launched Muse Spark Open, a giant AI model that anyone can download for free. Unlike most top-tier AI, which you access through a paid cloud service, this one can run on your own machines. That's a big deal for companies that want to keep their data private or avoid hefty cloud fees.

The model is massive—816 billion parameters (think of them as the AI's brain cells)—but it's designed to be efficient, using only a fraction at a time. It can also handle very long documents, up to a million words. Meta worked with Apple so that two high-end Mac Studios can team up to run it, acting like a single supercomputer. In tests, it helped write code and edit videos.

However, it's not the best at everything. On pure coding tasks, Chinese open models like Kimi K3 still score higher. Meta's model is great for 'agentic' tasks—where AI takes actions like calling tools or browsing—but trails on raw intelligence rankings. So if you need the absolute best coder, you might look elsewhere.

The real win is for businesses that need a US-made AI for compliance reasons. Many companies can't use foreign AI due to regulations. Muse Spark Open gives them a powerful, auditable option they can run on their own hardware. But be warned: running it locally requires serious hardware, so it's not for everyone. For most people, cloud-based AI remains cheaper and easier.
