Missing "Base URL" in my OpenAI Chat Model node

[yoan]

Describe the problem/error/question

I don’t have Base URL parameter in my OpenAI Chat Model node, as I usually do to connect with OpenRouter API.

However it’s still set on other workflows where I’ve already used it.

What is the error message (if any)?

I have the same issue and found the open router base url was inserted here

But the model selection was not auto update so still having the same issue to use open router.

Had the same issue, currently you need to copy name and paste it to model field of AI you want to use from.
Example:
microsoft/phi-4
sao10k/l3.1-70b-hanami-x1
deepseek/deepseek-chat

I tried still failed

Try to run workflow. I also had red trinagle, but when i ran actual workflow it worked

Thank you guys, it works !

I did the following :

1. I changed the base URL in my credentials,
2. changed the model to ‘deepseek/deepseek-chat’
3. ran the workflow
