Meta and Apple have introduced Muse Spark Open, an open‑weight AI model that runs locally on Apple‑silicon Macs.
Meta has unveiled Muse Spark Open, an open‑weight large language model designed to run locally on Apple‑silicon Macs. The company says the model is “the most capable U.S. open‑weight model to date” and that it brings advanced agentic capabilities to desktop machines such as the Mac Studio equipped with the M5 Ultra chip. Meta worked with Apple to optimise the software stack, allowing developers to deploy the model without relying on cloud services. According to the launch notes, the model’s full‑scale version requires roughly 1 TB of RAM, underscoring the high‑end hardware needed for peak performance.
The announcement builds on the collaboration reported earlier this month, when Meta and Apple first announced a partnership to make Muse AI models run more efficiently on Macs. Muse Spark Open marks the next step: an openly available weight set that can be inspected, fine‑tuned, or integrated into third‑party applications. By exposing the model’s parameters, Meta aims to lower the barrier for researchers and developers who want to experiment with large‑scale generative AI while keeping data and inference on‑device, a move that could ease privacy concerns and reduce reliance on expensive cloud compute.
The rollout is likely to influence several trends. First, it tests whether Apple’s high‑end silicon can support truly massive models, potentially spurring hardware upgrades or new memory‑expansion solutions. Second, the open‑weight stance may pressure competitors to release comparable models under permissive licenses, accelerating a shift toward more transparent AI ecosystems. Finally, developers will be watching for performance benchmarks, tooling updates, and any lighter‑weight variants that can run on less‑spec’d Macs. Those signals will indicate how quickly Muse Spark Open moves from a headline announcement to a usable component of the Nordic AI landscape.
