What do you want to do?

4 use cases

  • Serve a local chat API on a machine with no network

    Build the engines and run an OpenAI-style chat endpoint on one NVIDIA GPU with no downloads at build or start.

    View prompt
    In the UnbiasedStrata repo at <repo-path>, run make build and then make test, and report whether the test suite passed. Then start unbiased-strata with the model at <model-path> on port 18091 and confirm that GET /health returns a success response.

  • Ask a local model questions about screenshots

    Attach a projector file so the local server can read pictures such as dashboards, without sending them to a cloud API.

    View prompt
    In the UnbiasedStrata repo at <repo-path>, start unbiased-strata with the projector at <mmproj-path> and report the server log line that confirms the projector loaded. Then send the image at <image-path> to /v1/chat/completions and report the reply.

  • Test the server front end without a GPU or model

    Run the front end test suite against a fake engine to confirm a build works before any model is loaded.

    View prompt
    In the UnbiasedStrata repo at <repo-path>, run make build and make test and report the final pass or fail count. Confirm the tests ran against the fake engine and not a real model.

  • Prepare a Flash-Next pack for the strata engine

    Build the pack directory and MTP draft directory once so the strata engine can serve Qwen3.8-Flash-Next.

    View prompt
    In the UnbiasedStrata repo at <repo-path>, prepare the Flash-Next pack from the GGUF shard at <gguf-path> and report the output directory and its file list. Verify that draft_vocab.bin is present in the MTP directory before reporting success.

How to use Unbiased Strata

  1. Check you have what it needs: Linux x86-64 machine with one NVIDIA GPU (Pascal or newer) and CUDA 12.x; git and a C++ build toolchain able to run make build; GGUF model files copied to the machine by hand, since the fork does not download them.
  2. Open robertkarl/UnbiasedStrata on GitHub and read the README and license.
  3. Run git clone https://github.com/robertkarl/UnbiasedStrata then cd UnbiasedStrata. (inferred, check the README)
  4. Run git submodule update --init to fetch the pinned llama.cpp fork.
  5. Run make build to produce build/bin/strata-poly, build/bin/strata, libstrata_kq.so and unbiased-strata.
  6. Run make test to check the front end against a fake engine, with no GPU or model needed.

These steps come from our top use case, Serve a local chat API on a machine with no network, which also has a copy-paste agent prompt.
