From “Can It Run?” to Sovereign Hybrid RAG on DGX Spark – Qwen3‑80B + vLLM + LiteLLM (Live Stack) 1. Why I’m Sharing This Stack My DGX Spark is now running a full hybrid RAG stack with Qwen3‑80B at roughly 45 tok/s, under 150 ms end‑to‑end latency, and zero cloud on the critical path—and it already…

Thank you So much for these detailed and extremely useful guides! You have greatly helped this newbie along the path to spark’s greatness. Much appreciated and many kudos.

Thanks for the kind words and your contributions Mark. It’s very rewarding see the community growing and building together with lots of creative ideas. There’s more to come, some other folks in the community are reaching out and join forces so we can build a strong, collaborative and coherent ecosy…

Nice! Now if you add llama-swap to this setup, then you’ll be able to launch/switch models on demand. I run a similar stack - OpenWebUI → LiteLLM → llama-swap → vLLM (via our community docker/recipes)/llama.cpp, although since I’m constantly testing new models on Spark, llama-swap is temporarily out…

Optimizing Multi-Model Workflows in Open WebUI on DGX Spark for Enhanced Performance In developing AI pipelines, I have implemented sophisticated routing mechanisms, LiteLLM configurations, and fallback strategies. However, a subtle inefficiency persisted in my personal workflow when using Open Web…

Nice setup. What do you use to measure the accuracy of your system? Any issues with hallucinations? So far I’ve only had a play with Ragas.

Re: Hallucination testing — phased approach with academic grounding Thanks again for the Ragas pointer — hadn’t come across it before, so that’s now firmly on the list to dig into properly. The initial focus has been on academic STEM research. I have self‑hosted the full arXiv dataset — approximat…

Thank you so much for sharing!

Going to take me a few to go over moreover wanted to say thanks.
