"Hey everyone,
I am currently testing the capabilities of the new Screenplay activity. I am using the BYOM feature, and with GPT 4 and GPT 4 mini everything works as expected. However, I would also like to use the GPT 5 mini model, but I always get an ‘Internal Server Error’ when using that model.
Can somebody help me with this problem? Do I have to tweak settings somewhere else?"
Hi @MrDominitschku
Welcome to UiPath,
GPT-5 mini is currently not supported with UiPath Screenplay BYOM, so using it results in an Internal Server Error. There are no settings to tweak—only supported models like GPT-4 / GPT-4 mini will work until UiPath adds support for GPT-5 models.
If helpful, mark as solution. Happy automation with UiPath
GPT-5 mini isn’t supported by the Screenplay activity yet. That’s why it fails no settings to change. Only GPT-4 / GPT-4 mini work for now.
