Use 678API in Open WebUI
Connect Open WebUI to 678API through its OpenAI-compatible settings.
Adding a global connection through the UI normally requires Open WebUI administrator access. Regular users can only select models enabled by an administrator.
Admin settings
Sign in as an administrator and open Admin Panel / Settings, then Connections or OpenAI API.
Create an OpenAI-compatible connection named 678API with https://www.678api.com/v1 and a 678API API key.
Save and refresh the model list. If it is empty, verify key access and configure model IDs manually when supported.
Select a 678API model, send a short message, and confirm the request in 678API usage logs.
Environment variables
OPENAI_API_BASE_URL=https://www.678api.com/v1
OPENAI_API_KEY=YOUR_API_KEYAfter editing Docker Compose or container environment variables, recreate the Open WebUI container so it reads the new values. A browser refresh alone is not enough.
Common questions
- Users do not need to sign out of Open WebUI; account login and model connections are separate.
- A shared global key combines usage under that key. Create a dedicated key per instance or team when practical.
- If models appear but chats fail, run the
/modelscheck in Troubleshooting to isolate network and key issues.
