Apple and Meta have ended years of public clashes by partnering to run Meta’s massive Muse Spark Open AI model locally on high-end Mac hardware. This unusual collaboration combines Meta’s 816-billion-parameter open-weight model with Apple’s M5 Ultra-powered Mac Studios using the MLX framework, bypassing cloud infrastructure for local enterprise AI inference.
The alliance bridges two tech giants that have historically battled over privacy, advertising revenue, and ecosystem control. By leveraging the Mac Studio’s unified memory architecture, developers can now execute advanced agentic tasks directly from their desktop hardware.

How Apple and Meta Partnered for Muse Spark Open on Macs
Apple and Meta have ended their long-running rivalry to enable developers to run Meta’s 816-billion-parameter Muse Spark Open AI model locally on high-end Mac Studio desktops powered by M5 Ultra chips and Apple’s MLX framework, providing an alternative to cloud-only AI infrastructure.
Apple and Meta announced a technical collaboration allowing developers to run Meta’s Muse Spark Open model locally across two to four connected Mac Studio systems. Released by Meta as a free download for commercial use, the model features an 816-billion-parameter mixture-of-experts architecture with 42 billion active parameters and a 1-million-token context window.
The demonstration relies on Apple’s MLX framework to handle distributed inference across machines equipped with M5 Ultra chips. Each M5 Ultra supports up to 512GB of unified memory and 1.2TB/s of memory bandwidth. Because the model operates locally, Meta states it retains no visibility or control over user prompts, addressing longstanding privacy concerns that previously divided the two corporations.
Muse Spark Open and Mac Studio Hardware Specifications
| Specification Metric | Technical Detail |
|---|---|
| Model Architecture | Mixture-of-Experts (816B total / 42B active parameters) |
| Context Window | 1 Million Tokens |
| Hardware Platform | Mac Studio with M5 Ultra Chips |
| Memory Support | Up to 512GB Unified Memory (1.2TB/s bandwidth) |
| Optimization Framework | Apple MLX Framework for Distributed Inference |
| Base Entry Cost | $10,799 (256GB memory configuration) |
Strategic Implications and Hardware Costs for Local AI
This collaboration marks a significant shift from cloud-centric computing toward localized enterprise AI infrastructure. For years, running models of this scale required extensive Nvidia GPU clusters or cloud data centers. By optimizing for Apple’s unified memory, the partnership demonstrates that high-end personal computing hardware can handle demanding agentic workflows, coding, and video analysis locally.
However, accessibility remains constrained by steep hardware costs. A Mac Studio configuration featuring the required M5 Ultra chip and 256GB of memory starts at $10,799, with 512GB configurations scaling expenses higher. For businesses and developers, this setup offers heightened data security and reduced reliance on third-party cloud providers, though initial capital expenditure remains high.
The partnership also reflects shifting leadership dynamics. Meta AI chief Alexandr Wang noted that former Apple executive Daniel Gross facilitated the talks, while current Apple hardware engineering chief John Ternus publicly praised the integration. This joint effort runs parallel to Apple’s ongoing integrations with OpenAI and Google for Apple Intelligence and Siri, signaling a pragmatic approach to third-party AI partnerships.
Key Takeaways
- Apple and Meta partnered to bring Meta’s 816B-parameter Muse Spark Open model to M5 Ultra Mac Studios.
- Local execution via Apple’s MLX framework eliminates Meta data access, resolving historical privacy disputes.
- Hardware configurations starting at $10,799 provide an alternative to Nvidia GPUs and cloud data centers.
The Insider Take
The collaboration illustrates how hardware bandwidth constraints are reshaping enterprise software strategy. By validating local inference on consumer-grade workstation hardware, Apple and Meta are opening new avenues for developers seeking data sovereignty outside cloud ecosystems.
