Dify offers two routes. The UnoRouter plugin needs only your key and comes with ready models. The OpenAI-API-compatible provider takes one model at a time with its own settings.

Gotchas

• !Only workspace owners and admins can add model providers.
• !The OpenAI-API-compatible provider does not read the model list or detect capabilities. Add each model by hand and set its context size and features yourself.
