Open WebUI

The self-hosted chat UI, pointed at Tium through an admin connection.

Setup

Point Open WebUI at Tium

You need the base URL https://api.tium.ai/v1 and an API key from your dashboard. Keys are shown once at creation.

  1. 1.Open the connections admin

    Go to Settings, then Admin, then Connections, and find the Manage OpenAI API Connections list. Click the + Add Connection button.

    Settings > Admin > Connections
    URL                  https://api.tium.ai/v1
    API Key              sk-tium-...
    Model IDs (Filter)   leave empty
  2. 2.Fill in the URL and API Key, then Save

    The URL field suggests known providers as you type; ignore the suggestions and paste the base URL above.

Worth knowing

What Open WebUI gets wrong

Tool-specific behaviour that surprises people, and what to do about it.

Leave Model IDs (Filter) empty

That allowlist exists for providers with no /models endpoint. We serve an authenticated GET /v1/models, so Open WebUI discovers the catalog by itself, and anything typed into the filter becomes a second list to keep in sync with ours.

Running Open WebUI in Docker changes nothing here

The localhost-to-host.docker.internal substitution in their docs applies to a model server on your own machine. Tium is a public hostname and is reached the same way from inside a container as outside it.

Elsewhere

Other tools

The same base URL and key work anywhere that takes an OpenAI-compatible endpoint.
