Run Step-Audio-Chat 130B locally — what it takes

Step-Audio-Chat 130B (130B) is too large to hold on a single consumer or Apple GPU at FP16 (~260 GB of weights). It needs datacenter / multi-GPU memory:

  • ≈ 2× AMD Instinct MI325X
  • ≈ 2× NVIDIA B200

Lower precision (Q8 / FP8) reduces the requirement. Speed depends on the tool, resolution and steps.
