Connect Open WebUI

Updated

Self-hosted web UI that can serve local inference and a relay endpoint side by side.

Use cases

Good if you already run local inference: use local models and this platform's models side by side in one web UI.

Tips

Create a separate key for this client and limit its allowed models, so its usage is easy to track.

If it cannot connect

  1. Use https://omnimodel.me/v1 as the API host, without /chat/completions.
  2. The key starts with key_ and is not paused or revoked; auth.invalid_key means the key cannot be used.
  3. The model ID matches the catalog and is in the key's allowed models.
  4. billing.insufficient_credit means the balance is too low; see common errors for more.

Setup

  1. Go to Settings → Connections and add an OpenAI API connection.
  2. Fill in the API host and key below, then save.
  3. Refresh the model list and pick a model.

Settings

  • API host：https://omnimodel.me/v1
  • API key：YOUR_API_KEY

FAQ

Why is a model missing from the list?
Open WebUI fetches GET /v1/models, which shows only models your key can call. Check the key's allowed models and refresh.
Can I use it alongside local models?
Yes. Add the platform as an OpenAI-compatible connection; your local connections are unaffected.
