Expanding AI Api framework for offline / other models

I already connected my Claude api to BS Studio and it was already useful to find some obscure bugs in my css.

It can burn through your tokens really fast tho if you don’t precisely define what the context is and what shall be returned.

So I wanted to add my own APIs as my organization hosts it’s own openwebui service that provides different models like gpt, qwen and so on. But when I try to add those models in BS Studio I can’t make this work yet.

I implemented those models already in openclaw and python, so I’m certain that they work – but there’s no socket yet in the custom tab in BS Studio. I tried adding my gpt-5.4 model using openai as provider in custom but it didn’t work. I don’t really understand what those provider presets are if you can provide your own base url anyway – are these only for completing the url parameters or is there more behind it? It would be great to make this work somehow as my organization has a pretty high token limit. Or maybe I am missing something.

Thank you in advance!
