+- The availability of the GenAI prompt skill depends on the region availability of the chat completions model you choose. If you're using [Azure OpenAI Service](/azure/ai-services/openai/overview), refer to the [Azure OpenAI Service region availability](/azure/ai-services/openai/concepts/models) to check which regions support the specific model you selected. For other AI Foundry chat completions models, consult the region availability documentation provided for the respective model to ensure compatibility.
