Hi Alejandro Merino,
Thanks for Reaching the Microsoft Q&A Forum.
Currently, the Sweden Central region does not support the GPT-35-turbo models, which is why you're encountering this issue. The available regions for the GPT-35-turbo version 0125 are listed here. It appears that additional regions may be added in the future. For more information, please refer the screenshot.
I hope this helps.
