How to use embedding models with OpenRouter

[AADev]

Hi everyone,
I have used this OpenRouter credential settings that works as a chat model. However, I have the issue with using it as embedding model. Has anyone succeeded? Thanks!

Describe the problem/error/question

It does not seem to work the same way with any model I tried. Can we use embedding with open router, and model with for example: “google/gemma-2-9b-it:free” or “text-embedding-3-small” ?
Or what models with the OpenRouter could work for embedding?

What is the error message (if any)?

OpenRouter currently does not provide access to embedding models through its API. At the moment, it only offers API access to LLM models. To use ‘text-embedding-3-small,’ you may need to use an OpenAI API key instead.

Right, thank you. I am still finding various ways for connection, instead of the limited embedding.

@AADev, did you find a way with openrouter or another free embedding?
thanks
