5 use cases

  • Run a local Codex agent on a Strix Halo box

    Serve Qwen3.8-Flash-Next locally and point Codex at it through the Responses API.

    View prompt
    Using the repo peonist-ai/halogen-flash-server, configure Codex on <target machine> to use the local halogen server on port 8731, following docs/codex.md. Expected output: Codex completes a short test task against the local model and returns an answer. Verify that the server responds on port 8731 before running the test.

  • Point Claude Code at a local halogen server

    Serve the model on your own box and route Claude Code through the Messages API.

    View prompt
    Using the repo peonist-ai/halogen-flash-server, configure Claude Code on <target machine> to use the local halogen server on port 8731, following docs/claude-code.md. Expected output: a short Claude Code prompt returns a reply from the local model. Verify the server is listening on port 8731 before you test.

  • Resume a long agent session after a server restart

    Use the on-disk prompt cache so a deep agent session picks up without a cold start.

    View prompt
    Using the repo peonist-ai/halogen-flash-server, enable the on-disk prompt cache as described in docs/configuration.md and resume <target session> after a server restart. Expected output: the resumed session answers its next turn without reprocessing the full prompt. Verify by checking the time to first token against the first cold turn.

  • Benchmark decode and prefill on your own box

    Reproduce the published throughput numbers on your own Strix Halo machine.

    View prompt
    Using the repo peonist-ai/halogen-flash-server, run the prefill and decode benchmarks described in docs/performance.md on <target machine>. Expected output: a table of prefill tok/s and decode tok/s for each prompt length and text type. Verify the host settings match docs/troubleshooting.md before comparing against the published 0.18.0 figures.

  • Use the server as a text classifier endpoint

    Send labeling and classification requests to the local model through the classify endpoint.

    View prompt
    Using the repo peonist-ai/halogen-flash-server, send the texts in <input file> to the classify endpoint as described in docs/CLASSIFY.md. Expected output: one label per input text. Verify the labels on ten known examples before running the full batch.

How to use Halogen Flash Server

  1. Check you have what it needs: An AMD Strix Halo machine (the README measures on a Ryzen AI Max+ 395 with 128 GB); Podman installed, with access to /dev/kfd and /dev/dri; Access to the BIOS to set the UMA frame buffer carve-out to its minimum.
  2. Open peonist-ai/halogen-flash-server on GitHub and read the README and license.
  3. Set the BIOS carve-out (UMA frame buffer) to its minimum, not Auto, as described in docs/host-setup.md.
  4. Run mkdir -p ~/halogen-models
  5. Run podman run --rm -p 8731:8731 --device /dev/kfd --device /dev/dri --group-add keep-groups --ipc=host --ulimit memlock=-1:-1 -e HALOGEN_DOWNLOAD=peonist-ai/halogen-qwen3.8-flash-next -v ~/halogen-models:/models ghcr.io/peonist-ai/halogen-flash-server:0.18.12 (inferred, check the README)
  6. Follow docs/codex.md to point Codex at the Responses API on the server.

These steps come from our top use case, Run a local Codex agent on a Strix Halo box, which also has a copy-paste agent prompt.
