Roo Code is an extension to VSCode, and I quote them verbatim:

Roo Code is an open-source, AI-powered coding assistant that runs in VS Code. It goes beyond simple autocompletion by reading and writing across multiple files, executing commands, and adapting to your workflow—like having a whole dev team right inside your editor.

I am very new to Roo Code, and frankly, my main interest is not in actually using Roo Code but rather to get it up-and-running with locally hosted models. Roo Code supports Ollama and that is likely the simplest way to get it to work locally as Ollama is super simple to get running. I have however chosen to go for vLLM because I'm aiming for the highest throughput and because I want to check out vLLM. My initial test is with DeepSeek-R1-Distill-Qwen-14B and the following docker compose is what I use to get vLLM up and running.

To fit the code on two RTX 3090s I'm using –dtype float16 and since I'm… TBC
