IQ3XXS giving garbage output

#33
by mbhagya - opened

I downloaded the IQ3XXS version and tried to run it with llamacpp both ways - with and without the newly introduced spec-type argument. But in both the cases, the model produces random characters as output. Here's the command I used:

./llama-server -m ~/.lmstudio/models/unsloth/Qwen3.6-27B-MTP-GGUF/Qwen3.6-27B-UD-IQ3_XXS.gguf --no-mmproj -ngl 99 -c 8192 -np 1

I am able to run the regular models but not this one. Am I missing something or this quant has a problem?

I tried IQ3XXS, and Q3K_XL & there was no speed advantage over Q4K_XL on 8GB VRAM (RTX 3070). May as well go for better accuracy with a bigger model, unless you have some other reason, such as limited system RAM.

Check your CUDA version - think I read there's an issue with 13.2 and quants less than Q4. 13.0 will work fine apparently.
