+## Cross-Region Inference
+
+Amazon Bedrock now permits cross-region inference, where a model hosted in a different region than that of the user may be specified, see the [inference profiles documentation](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles-support.html). Such models have IDs prefixed by a region identifier such as `us.meta.llama3-2-1b-instruct-v1:0`, for example. To use this feature, simply enter the Inference profile ID for the cross-region model instead of the ARN.

+## Summary
+
+1. Bedrock Base models: All available models will already be available in the drop down model list. The above interface also allows use of base model IDs or ARNs, though this is unnecessary as they are in the dropdown list.
+2. Bedrock Custom models: If you have fine-tuned a Bedrock base model you may use the ARN for this custom model. Make sure to enter the correct provider information, such as `amazon`, `anthropic`, `cohere`, `meta`, `mistral` (always in lower case).
+3. Provisioned Models: These are models that run on dedicated endpoints. Users can purchase Provisioned Throughput Model Units to get faster throughput. These may be base or custom models. Enter the ARN for these models in the Model ID field.
+4. Cross-region Inference: Use the Inference profile ID for the cross-region model instead of the ARN.

 ### Amazon Bedrock Usage
 
-Jupyter AI enables use of language models hosted on [Amazon Bedrock](https://aws.amazon.com/bedrock/) on AWS. First, ensure that you have authentication to use AWS using the `boto3` SDK with credentials stored in the `default` profile. Guidance on how to do this can be found in the [`boto3` documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html).
