Raw Blame History

  • Decision: corrected benchmark scope because previous comparison used ComfyUI GGUF default, not ComfyUI best; fair baseline is ComfyUI fp8 + --fast + compile where available.
  • Decision: ComfyUI 0.26.0 exposes fp8_e4m3fn, fp8_e4m3fn_fast, fp8_e5m2; no dynamic int8; nvfp4 only via prequantized file.
  • Edited /mnt/disks/unslothai/ubuntu/workspace_81/unsloth/scripts/comfy_bench.py: added UNETLoader-based flux.1-fp8, qwen-image-fp8, and qwen-image-nvfp4 benchmark workflows.
  • Edited /mnt/disks/unslothai/ubuntu/workspace_81/unsloth/outputs/FINAL_engine_comparison.md: updated final table/verdict to best-vs-best: FLUX ComfyUI 1.00s vs ours 0.518s; Qwen ComfyUI 6.01s vs ours 1.78s.
  • Commands/results: started ComfyUI --fast on port 8234; confirmed UNETLoader sees fp8/nvfp4 files; downloaded flux1-schnell-fp8.safetensors 17.24 GB, qwen_image_fp8_e4m3fn.safetensors 20.43 GB, qwen_image_nvfp4.safetensors 19.77 GB.
  • Bench results: ComfyUI fp8 no compile FLUX 1.00s/25.2GB, Qwen 6.01s/49.4GB; fp8+compile FLUX 1.01s/62.9GB, Qwen 6.06s/81.3GB; nvfp4+compile Qwen 14.16s/101.1GB.
  • Errors: compound restart/kill commands exited 144 due pkill; resolved by standalone launch and individual kill; ComfyUI procs remaining 0.
  • COMPLETED: corrected FLUX.1 and Qwen best-vs-best GPU comparison and writeup.
  • PENDING: optional fp8 best-vs-best rerun for Z-Image and FLUX.2-klein.
