I have an rx 6800. Looks like exllamav3 doesn't support AMD cards yet... I'll keep an eye on it, so I can try it when ROCm or Vulkan support is added.

Ah. You can still run them in exllamav2, but you're probably better off with ik_llama.cpp then:

https://github.com/ikawrakow/ik_llama.cpp

It supports special "KT" quantizations, aka trellis quants similar to exllamav3, and will work with vulkan (or rocm?) on your 6800.

Quantizing yourself is not too bad, but if you want, just ping me, and I can make some 16GB KT quants, or point you to how to do it yourself.

It's also a good candidate for Qwen3 30B with a little CPU offloading. ik_llama.cpp is specifically optimized for MoE offloading.

Welcome to LocalLLaMA! Here we discuss running and developing machine learning models at home. Lets explore cutting edge open source neural network technology together.

Rule 1 - No harassment or personal character attacks of community members. I.E no namecalling, no generalizing entire groups of people that make up our community, no baseless personal insults.

Rule 2 - No comparing artificial intelligence/machine learning models to cryptocurrency. I.E no comparing the usefulness of models to that of NFTs, no comparing the resource usage required to train a model is anything close to maintaining a blockchain/ mining for crypto, no implying its just a fad/bubble that will leave people with nothing of value when it burst.

Rule 3 - No comparing artificial intelligence/machine learning to simple text prediction algorithms. I.E statements such as "llms are basically just simple text predictions like what your phone keyboard autocorrect uses, and they're still using the same algorithms since <over 10 years ago>.

Rule 4 - No implying that models are devoid of purpose or potential for enriching peoples lives.
