If it will not connect

  • Keep /v1 at the end of the Base URL and add nothing after it; Jan adds /chat/completions itself.
  • To update the model list later, open the Onomeo provider in Settings and press the refresh button on the Models row again.
  • 401: the key is wrong; open the Onomeo provider and correct the key under API keys. 402: insufficient balance. Claude, GPT and other big models are charged by usage; top up on the Pricing page or switch to a free model.
  • Once your own provider keys are connected on the My providers page, their models also appear in the list after a refresh, with names starting my/. This site does not charge for those calls.
