About

weighted/imatrix quants of https://huggingface.co/mosaicml/mpt-30b-chat

*no more quants forthcoming, as llama.cpp corrupts them and crashes

static quants are available at https://huggingface.co/mradermacher/mpt-30b-chat-GGUF

Usage

If you are unsure how to use GGUF files, refer to one of TheBloke's READMEs for more details, including on how to concatenate multi-part files.

Provided Quants

(sorted by size, not necessarily quality. IQ-quants are often preferable over similar sized non-IQ quants)

Link	Type	Size/GB	Notes
GGUF	i1-IQ2_M	10.2
GGUF	i1-Q2_K	11.4	IQ3_XXS probably better
GGUF	i1-IQ3_XXS	11.8	lower quality
GGUF	i1-IQ3_M	14.6
GGUF	i1-Q3_K_M	15.8	IQ3_S probably better
GGUF	i1-Q4_K_S	17.2	optimal size/speed/quality
GGUF	i1-Q4_K_M	19.2	fast, recommended
GGUF	i1-Q6_K	24.7	practically like static Q6_K

Here is a handy graph by ikawrakow comparing some lower-quality quant types (lower is better):

FAQ / Model Request

See https://huggingface.co/mradermacher/model_requests for some answers to questions you might have and/or if you want some other model quantized.

Thanks

I thank my company, nethype GmbH, for letting me use its servers and providing upgrades to my workstation to enable this work in my free time. Additional thanks to @nicoboss for giving me access to his private supercomputer, enabling me to provide many more imatrix quants, at much higher quality, than I would otherwise be able to.
