Who it is forA developer or small team that wants to point existing OpenAI API client code at a model hosted on their own AMD Strix Halo machine instead of a cloud service.
The problemCloud model APIs send data off the machine and bill per request, and most large models do not fit on a single consumer box.
The outcomeA local server on port 8000 that answers OpenAI API requests using a 300B-class MoE model class on one machine.
What you need first
- AMD Ryzen AI Max+ 395 mini PC with 128 GB of memory (Strix Halo, gfx1151)
- ROCm build of torch, installed per doc/install.md
- Python and the hf command-line tool to download model packs
- Roughly 100 GB of free disk space for a model pack (Qwen pack is 95 GB)
Steps
- Install ROCm torch and build Kyojin once by following doc/install.md.
git clone https://github.com/Yamz-Labs/kyojin && cd kyojinhf download yamz-labs/Qwen3.8-Flash-Next-EXL3-Yamz --local-dir ./qwen-packpython tools/qwen/serve.py --model ./qwen-pack --port 8000 -c 131072- Point your OpenAI API client at port 8000 on the machine and send a test chat request.
Prompt for your agent
In the Yamz-Labs/kyojin repo, follow doc/install.md, then download the Qwen3.8-Flash-Next pack and start tools/qwen/serve.py on port 8000 on <target host>. Expected output: the server starts and answers one OpenAI API chat request with text. Verify that the response JSON includes a choices array before reporting success.
Caveat. The README says the software targets AMD Strix Halo with ROCm (gfx1151), so it will not run on other hardware as documented.
