What do I need to insert into the 'ai embeddings discourse service api endpoint'

Greetings dear forum participants :wave:
I didn’t know whether to publish this post as a separate topic and decided to write here.
Perhaps my question will be stupid, but tell me what link (and where to get it) I need to insert into the ai embeddings discourse service api endpoint line in the Discourse AI? Screenshot:

Edit: Same question on the line ai summarization discourse service api endpoint

That matters if you are using self hosted system, I reckon. If you are using OpenAI-API instead you will leave it empty.

@Jagster Thanks for the quick response :raised_hands:
I’m using OpenAI API.
