Meta's open Muse Spark needs 493GB of memory — far beyond any consumer laptop

- Developer Tejas Kumar mapped local-run memory requirements for Meta's open-weights Muse Spark: 1,600GB at BF16 full precision, 493GB at 4-bit NVFP4, and 180–212GB even with Unsloth's 1-bit quantization.
- His MacBook Pro has 16GB; the 512GB Mac Studio used in Meta's demo isn't on sale yet.
- He invokes MKBHD's rule: buy the product as it is today, not as promised — implying the open release's practical usability is questionable.
