Welcome to LocalLLaMA! Here we discuss running and developing machine learning models at home. Lets explore cutting edge open source neural network technology together.
Get support from the community! Ask questions, share prompts, discuss benchmarks, get hyped at the latest and greatest model releases! Enjoy talking about our awesome hobby.
As ambassadors of the self-hosting machine learning community, we strive to support each other and share our enthusiasm in a positive constructive way.
Rules:
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.
I recently got a 7900 XTX. It’s about the cheapest 24GB card still available at a reasonably sane price. I’m running Qwen 3.8 27B on llama.cpp with 200k context at 4 bit quant with 700 t/s prefill and 30 t/s decode.
Edit:
I just read through the linked article and the one thing it doesn’t mention is quantized KV cache. I’m running 4 bit on both the model and the cache so I can fit 200k context in 24GB. It works really well and I don’t really notice a difference between my setup and Claude Sonnet 5 that I use at work.
128GB sounds nice for running even larger models, but probably not something I can justify in my budget at today’s prices. My XTX was like $700 after trading in my 3070, so I was able to do that.
Edit 2:
Damn, the cheapest XTX I see new now is $1400. Mine was in the $900s a couple months ago. They’re still going in the $800s used on eBay, which is still better than $1500 for a used 3090.
Absolutely insane prices. This bubble got to go.
