What Hacker News made of it
The launch thread has 475 comments, and most of them are not about the benchmarks. They are about the phrase "open weights" attached to a model that needs two Mac Studios, about the gated model card, and about whether a 1.65 TB checkpoint is a download or a procurement. The second thread, on Apple's MLX post, is where the hardware argument gets specific.

Muse Spark Open
The main Hacker News discussion of the release: parameter count, memory footprint, licence terms and what 'open weights' should mean.
The launch thread and by far the biggest: 475 comments in two days, most of them about whether an 816B model that needs two Mac Studios or eight GPUs is really open in any useful sense.

Apple ML Research: Muse Spark Open with MLX on Mac Studio
Discussion of Apple's MLX and RDMA benchmark: pipeline versus tensor parallelism, NVFP4 memory footprint, and the four-Mac Studio setup.
Apple's distributed-inference post, and the thread is more useful than the announcement: people compare 36 tokens per second on four Mac Studios with what a single GPU node costs and conclude the desktop story is real but narrow.

Muse Spark Open, the Most Capable US Open-Weight Model to Date
An earlier submission of Meta's launch post, with a short comment thread.
The second submission of the same launch post, posted 49 minutes earlier and mostly absorbed by the larger thread. Worth keeping because its single comment asks the question the launch table does not answer: what the model costs to run.

Build with Muse Spark Open
Meta's developer launch post and the cookbook patterns it ships: orchestration, fan-out, computer use, GitHub agents, search grounding.
The developer-facing launch post, with cookbooks for multi-agent orchestration, agent fan-out, computer use, a GitHub agent and search grounding. It got little attention on Hacker News, which is a gap rather than a verdict.

Muse Spark Open 816B-A42B
The model card on Hugging Face and the access request it requires.
The Hugging Face model card submission. Two comments, both about access: the weights are gated behind a manual request, which is the detail that separates 'open weights' from a download button.
What this column does not have
Reddit and dev.to. Reddit's search endpoint answers 403 to us, and dev.to has no tag for this model yet. A thread index that pretended to cover them would be guessing, so this page is Hacker News and says so.
