Hello @Jose Menedez
Thanks for reaching out to us, currently GPT-4 does not support in UK South region and there is no near future plan about it. Alternatively, you can consider GPT-4 France Central and GPT-3.5 which supported in South UK.
More information please refer to - https://learn.microsoft.com/en-us/azure/ai-services/openai/concepts/models
I hope this helps.
