 - Resources deployed with Azure CLI won't work out-of-box with Azure OpenAI global batch. This is due to an issue where resources deployed using this method have endpoint subdomains that don't follow the `https://your-resource-name.openai.azure.com` pattern. A workaround for this issue is to deploy a new Azure OpenAI resource using one of the other common deployment methods which will properly handle the subdomain setup as part of the deployment process.
 
+- UTF-8-BOM encoded `jsonl` files are not supported. JSON lines files should be encoded using UTF-8. Use of Byte-Order-Mark (BOM) encoded files is not officially supported by the JSON RFC spec, and Azure OpenAI will currently treat BOM encoded files as invalid. A UTF-8-BOM encoded file will currently return the generic error message: "Validation failed: A valid model deployment name could not be extracted from the input file. Please ensure that each row in the input file has a valid deployment name specified in the 'model' field, and that the deployment name is consistent across all rows."

 The content filtering system integrated into Azure AI Foundry runs alongside the core models, including DALL-E image generation models. It uses an ensemble of multi-class classification models to detect four categories of harmful content (violence, hate, sexual, and self-harm) at four severity levels respectively (safe, low, medium, and high), and optional binary classifiers for detecting jailbreak risk, existing text, and code in public repositories.

+## Specify a content filtering configuration at request time (preview)
+
+In addition to the deployment-level content filtering configuration, we also provide a request header that allows you specify your custom configuration at request time for every API call. 
+
+```bash
+curl --request POST \ 
+    --url 'URL' \ 
+    --header 'Content-Type: application/json' \ 
+    --header 'api-key: API_KEY' \ 
+    --header 'x-policy-id: CUSTOM_CONTENT_FILTER_NAME' \ 
+    --data '{ 
+        "messages": [ 
+            { 
+                "role": "system", 
+                "content": "You are a creative assistant." 
+            }, 
+            { 
+                "role": "user", 
+                "content": "Write a poem about the beauty of nature." 
+            } 
+        ] 
+    }' 
+```
+
+The request-level content filtering configuration will override the deployment-level configuration, for the specific API call. If a configuration is specified that does not exist, the following error message will be returned. 
+
+```json
+{ 
+    "error": 
+        { 
+            "code": "InvalidContentFilterPolicy", 
+            "message": "Your request contains invalid content filter policy. Please provide a valid policy." 
+        } 
+} 
+```
