DeepSeek Harness (dsh)

DeepSeek Harness (dsh) is DeepSeek's open-source agent runtime. It connects to any gateway through a custom provider — base URL, protocol and model IDs, nothing hardcoded. Function calling and streaming usage have been verified end to end against the HopBase gateway.

Settings file

Add a provider to $DSH_HOME/settings.yaml:

providers:
  hopbase:
    api: openai-completions
    baseURL: https://api.hop-base.com/v1
    apiKeyEnv: HOPBASE_API_KEY
    models:
      - id: deepseek-v4-pro-202606
      - id: deepseek-v4-flash-202605
      - id: glm-5.3

Export the key before launching: export HOPBASE_API_KEY=sk-your-key.

Web UI

Settings → Models → Add a custom provider, then fill in the same values. Pick the protocol by model family:

Use the exact model IDs returned by GET /v1/models for your plan key. Claude models need a Claude plan key.
