I am trying to make it easier to use LLMs on older, cheaper, smaller GPUs. I'm taking a similar approach (move MoE expert weights to disk, avoid wasting VRAM on these). My goal is also to run models that do not fit. My work also suffers from AI documentation issues. Where my approach differs is that instead of running an LLM that doesn't fit slowly, run many agents in parallel sharing the streams of MoE experts weights, to increase throughput. I envision a team of AI agents sharing a pretty-good-at-coding LLM that does not fit to collaborate on a set of related features, being developed in parallel.
My work is showing promising results (if you can get past the way the AI tries to describe what I am doing). https://sw-ml-study.github.io/emufpga/index.html
I am doing this work initially on a 6-Xeon-cores Linux workstation with an RTX5060-16G to run MoE models larger than that. Then I will be moving this to a server with a lot more cores (Dual 32-cores) and a mix of SAS HD and SSD drives, using older GPUs.
Ultimately, I hope to build some FPGA/MCU "accelerators" that process the expert weights on systems with not enough CPU cores to offload the experts. If I can enable large capable models to run on older hardware, keeping the limited GPU VRAM for context and things that must be in VRAM, I can get useful work out of my old refurbished systems without paying today's RAM and VRAM/GPU prices.
