Meta and Apple have jointly developed an open-weights AI model, Muse Spark Open, optimised for Apple's upcoming M5 Mac Studio Ultra. The collaboration marks a rare alliance between the tech rivals in the artificial intelligence space.
01Summary
- 01Muse Spark Open is an open-weights AI model with 42 billion active parameters and a million-token context window, available on HuggingFace under Meta's Muse Model license.
- 02The model was created by Meta and optimised with Apple's hardware team to run on the M5 Mac Studio Ultra, requiring two units costing $5,499 each.
- 03Meta CEO Mark Zuckerberg and Apple CEO John Ternus emphasised the focus on on-device AI, which allows data to be kept more secure and can be cheaper long-term than cloud subscriptions.
- 04Apple has historically taken a cautious approach to AI development, while Meta has invested billions, and the two companies have clashed over privacy and data collection—notably when Apple's app tracking opt-out cost Meta $10 billion in 2022.
- 05The partnership underscores Meta's strategy to build open-weights AI models and Apple's focus on hardware capable of running compute-intensive AI tasks.
02Why it matters
This collaboration signals that on-device AI is becoming a priority, which could mean more secure, customisable AI tools for developers and businesses, albeit with expensive hardware requirements.
