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.

- CamperBob2 8mo agoPlease 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.
- danielhanchen 8mo agoOh 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
- Keats 8mo agoIs 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.
- mirekrusin 8mo agoIt takes download time + 1 minute to test speed yourself, you can try different quants, it's hard to write down a table because it depends on your system ie. ram clock etc. if you go out of gpu. I guess it would make sense to have something like max context size/quants that fit fully on common configs with gpus, dual gpus, unified ram on mac etc.
- Keats 8mo agoTesting speed is easy yes, I'm mostly wondering about the quality difference between Q6 vs Q8_K_XL for example.
- danielhanchen 8mo agoI haven't done benchmarking yet (plan to do them), but it should be similar to our post on DeepSeek-V3.1 Dynamic GGUFs: https://unsloth.ai/docs/basics/unsloth-dynamic-2.0-ggufs https://unsloth.ai/docs/basics/unsloth-dynamic-2.0-ggufs
- segmondy 8mo agoThe green/yellow/red indicators are based on what you set for your hardware on huggingface.
- ranger_danger 8mo agoWhat is your definition of "important" in this context?
- danielhanchen 8mo agoOh we wrote about it here: https://unsloth.ai/docs/basics/unsloth-dynamic-2.0-ggufs https://unsloth.ai/docs/basics/unsloth-dynamic-2.0-ggufs
