UD stands for "Unsloth-Dynamic" which upcasts important layers to higher bits. Non UD is just standard llama.cpp quants. Both still use our calibration dataset.

Please consider authoring a single, straightforward introductory-level page somewhere that explains what all the filename components mean, and who should use which variants.

The green/yellow/red indicators for different levels of hardware support are really helpful, but far from enough IMO.

  • Oh good idea! In general UD-Q4_K_XL (Unsloth Dynamic 4bits Extra Large) is what I generally recommend for most hardware - MXFP4_MOE is also ok

    • Is there some indication on how the different bit quantization affect performance? IE I have a 5090 + 96GB so I want to get the best possible model but I don't care about getting 2% better perf if I only get 5 tok/s.

  • The green/yellow/red indicators are based on what you set for your hardware on huggingface.
