Set Up a DeepSeek API Key in DeepSeek Harness
Enter the DeepSeek API key in the local Web UI settings or use the documented environment/credential layers for deployed profiles. This site never asks for, stores or proxies a key, and example values must always remain placeholders. This page separates verified behavior from community reports and marks the release-candidate context so you can act without mistaking an observation for a permanent guarantee.
What is verified now
Enter the DeepSeek API key in the local Web UI settings or use the documented environment/credential layers for deployed profiles. This site never asks for, stores or proxies a key, and example values must always remain placeholders.
Evidence basis: Official provider/credential docs. The status was checked on 14 August 2026; re-check the linked source after any dsh release.
Safe workflow
Use the smallest reversible workflow first. Do not add community plugins or paste credentials while validating the base behavior.
- Validate the provider base URL and credential source.
- Select an exact model identifier exposed by that route.
- Send a minimal request before enabling tools or plugins.
Verify before moving on
A successful result should be observable: a version string, reachable local URL, valid provider response, loaded configuration, or disappearance of the exact error. If the result differs, stop and capture sanitized evidence rather than stacking unrelated fixes.
- Record the exact dsh, Node or Python version.
- State the operating system and installation method.
- Link the first-party source and include only sanitized logs.
First-party sources
Open the original source before acting on a changed version or unresolved community report.
