I’ve been working on a project called L88 — a local RAG system that I initially focused on UI/UX for, so the retrieval and model architecture still need proper refinement.

Repo: https://github.com/Hundred-Trillion/L88-Full

I’m running this on 8GB VRAM and a strong CPU (128GB RAM). Embeddings and preprocessing run on CPU, and the main model runs on GPU. One limitation I ran into is that my evaluator and generator LLM ended up being the same model due to compute constraints, which defeats the purpose of evaluation.

I’d really appreciate feedback on:

Better architecture ideas for small-VRAM RAG

Splitting evaluator/generator roles effectively

Improving the LangGraph pipeline

Any bugs or design smells you notice

Ways to optimize the system for local hardware

I’m 18 and still learning a lot about proper LLM architecture, so any technical critique or suggestions would help me grow as a developer. If you check out the repo or leave feedback, it would mean a lot — I’m trying to build a solid foundation and reputation through real projects.

Thanks!
