Meta and Apple Bring Muse Spark Open AI Model to Mac Studio

3 weeks 2 days ago
Meta has released Muse Spark Open, an 816-billion-parameter open-weight model optimized to run locally across two 512GB M5 Ultra Mac Studios using Apple's MLX framework. Meta says it's the "most capable U.S. open-weight model to date." MacRumors reports: Muse Spark Open has 816 billion total parameters with 42 billion active parameters and a 1 million-token context window. It is meant for coding and agentic work, and Meta says it excels at extended tasks, multi-step reasoning, and software engineering. The new Muse model was tuned to run on Mac Studio, and Meta says the Mac Studio paired with Muse Spark Open is the "best way to run a powerful model on your own desktop." From Meta: "Apple's unified memory architecture lets the M5 Ultra's integrated GPU use up to 512 GB per Mac Studio, so two machines can hold an entire model. And the chip's 1.2 TB/s of memory bandwidth is fast enough to read the small slice each token needs. The result is two Mac Studios behave like one supercomputer with a terabyte of unified memory." Apple hasn't released the 512GB Mac Studio as of yet, but it's supposed to be coming later this month. It won't be cheap, because the 256GB Mac Studio is already priced over $10,000.

Microsoft Says Windows 11 Is Now 'More Responsive', Runs Better On 8GB of RAM

3 weeks 2 days ago
Microsoft says recent Windows 11 updates have made the operating system up to 20% more responsive by improving memory management and reducing background resource use. "A big part of that work is making smarter use of memory and system resources," says Navjot Virk, corporate vice president of Windows experiences at Microsoft. "We've improved memory management and efficiency across Windows to help keep more of your PC's resources focused on what you're actively doing." The Verge reports: The improvements to memory management now make a "meaningful difference" on PCs with just 8GB of RAM. "Windows can now keep up to 2GB more of your active data in memory instead of moving it to slower storage," says Virk. "For example, on PCs with 8GB of memory or less, Widgets load only when you open them, making more than 200 MB of memory available for your apps and other work." Microsoft has also made Windows Update less disruptive, cleaned up the Widgets section, and finally allowed the taskbar to be repositioned to the sides or top of a display. Windows Hello sign-in has also been sped up, and Bluetooth pairing is more reliable, "including an AirPods pairing experience that's up to 15 seconds faster." The next big step is a new Windows Search experience that's a lot faster and more capable. [...] It's currently available for Windows Insiders, and Microsoft says it will "roll out more broadly later this year."
