When adding custom models, we should be able to set specific base URLs for each model. I recently tried adding GLM-4.7 to the custom models and needed to override the base URL to z.ai’s endpoint but in setting that override, the ability to use all of the others models broke. I would like to be able to create a new model and base URL such that I can use that custom model successfully but if I switch to GPT-5.2, those calls will continue to work without having to disable the openAI base url override.
Hey, thanks for the request. This is a known limitation. A few users have hit the same issue when trying to use multiple custom models with different endpoints at the same time.
A similar request was posted 8 days ago:
This feature is in progress. The team is working on fixing how “Override OpenAI Base URL” behaves with custom models. For now, the only workaround is to manually switch the Override Base URL in settings when you switch models.
I’ll add your use case to the existing thread so the team can see the demand.
I swore I looked for this and didn’t see it (it’s late, I may be misremembering) and then I saw tons of related posts about the same. Glad to see the team is looking into this, thx Dean
