Run LongCat-Flash locally — what it takes
LongCat-Flash (560B) is too large to run on a single consumer or Apple machine. At Q4 its weights alone are about 314 GB — it needs a multi-GPU / datacenter setup:
- ≈ 2× AMD Instinct MI325X
- ≈ 2× NVIDIA B200
Lower quantization (Q3/Q2) or CPU + system-RAM offload (e.g. ktransformers) reduces the requirement at the cost of speed.
