Memory needed vs common local setups (UD-Q4_K_XL 249.4 GB)

Thanks for the quants. For anyone checking whether this fits their machine, quick math from the file sizes in this repo (HF API, 23 Oct):

  • UD-Q4_K_XL: 249.4 GB of files (7 shards)
  • UD-Q8_K_XL: 259.1 GB (only ~4% bigger, since the experts already ship in 4-bit)

That's files only, before KV cache and runtime overhead. Usable memory on common setups (our estimates):

  • 24 GB GPU: ~23.4 GB
  • 32 GB GPU: ~31.4 GB
  • 128 GB unified (Mac / DGX Spark class): ~96 GB
  • 256 GB Mac Studio: ~192 GB

So UD-Q4_K_XL doesn't fit fully on any single consumer box; you need about 256 GB+ of GPU memory, or offload most experts to system RAM (with 23B active per token, CPU offload is usable but slow). A 2-bit quant (about 156 GB in the community repos) is the only size that fits under ~192 GB.

We keep per-GPU fit estimates here: https://localllmrig.com/can-i-run?utm_source=huggingface&utm_medium=community&utm_campaign=minimax-m3-1-flash

Happy to correct anything if someone has measured numbers.
