-### NEW Data Zone standard deployment type
+### NEW data zone standard deployment type
 Data zone standard deployments are available in the same Azure OpenAI resource as all other Azure OpenAI deployment types but allow you to leverage Azure global infrastructure to dynamically route traffic to the data center within the Microsoft defined data zone with the best availability for each request. Data zone standard provides higher default quotas than our Azure geography-based deployment types.  Data zone standard deployments are supported on `gpt-4o-2024-08-06`, `gpt-4o-2024-05-13, and `gpt-4o-mini-2024-07-18` models.
