Make OLMo Models available

I need to use https://openrouter.ai/allenai/olmo-2-0325-32b-instruct

It is not found when using import Open Router functionality and it doesn’t work to import it manually.

This is the error message:
Sorry, allenai/olmo-2-0325-32b-instruct has rejected your request. Here is the error message from allenai/olmo-2-0325-32b-instruct: no endpoints found for allenai/olmo-2-0325-32b-instruct.

What am I missing?
