+### Bedrock Cross-Region Inference
+
+
+Cross-Region Inference supports accessing foundation models across regions, allowing users to invoke models hosted in different AWS regions for inference. Main advantages:
+- **Improved Availability**: Provides regional redundancy and enhanced fault tolerance. When issues occur in the primary region, services can failover to backup regions, ensuring continuous service availability and business continuity.
+- **Reduced Latency**: Enables selection of regions geographically closest to users, optimizing network paths and reducing transmission time, resulting in better user experience and response times.
+- **Better Performance and Capacity**: Implements load balancing to distribute request pressure, provides greater service capacity and throughput, and better handles traffic spikes.
+- **Flexibility**: Allows selection of models from different regions based on requirements, meets specific regional compliance requirements, and enables more flexible resource allocation and management.
+- **Cost Benefits**: Enables selection of more cost-effective regions, reduces overall operational costs through resource optimization, and improves resource utilization efficiency.
+
+
+Please check [Bedrock Cross-Region Inference](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference.html)
+
+**limitation:**
+Currently, Bedrock Access Gateway only supports cross-region Inference for the following models:
+- Claude 3 Haiku
+- Claude 3 Opus
+- Claude 3 Sonnet
+- Claude 3.5 Sonnet
+
+**Prerequisites:**
+- IAM policies must allow cross-region access,Callers need permissions to access models and inference profiles in both regions (added in cloudformation template)
+- Model access must be enabled in both regions, which defined in inference profiles 
+
+**Example API Usage:**
+- To use Bedrock cross-region inference, you include an inference profile when running model inference by specifying the ID of the inference profile as the modelId, such as `us.anthropic.claude-3-5-sonnet-20240620-v1:0`
+
+```bash
+curl $OPENAI_BASE_URL/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $OPENAI_API_KEY" \
+  -d '{
+    "model": "us.anthropic.claude-3-5-sonnet-20240620-v1:0",
+    "max_tokens": 2048,

+### Bedrock Cross-Region Inference
+
+Cross-Region Inference 支持跨区域访问的基础模型,即允许用户在一个 AWS 区域中调用其他区域的基础模型进行推理。主要优势:
+- **提高可用性**: 提供区域冗余，增强容错能力。当主要区域出现问题时可以切换到备用区域，确保服务的持续可用性和业务连续性
+- **降低延迟**: 可以选择地理位置最接近用户的区域,优化网络路径，减少传输时间,提供更好的用户体验和响应速度
+- **性能和容量优化**: 实现负载均衡，分散请求压力,提供更大的服务容量和吞吐量,能够更好地处理流量峰值
+- **灵活性**: 根据需求选择不同区域的模型,满足特定地区的合规要求,更灵活的资源调配和管理
+- **成本效益**: 可以选择成本更优的区域,通过优化资源使用降低总体运营成本,更好的资源利用效率
+
+详细介绍请查看[Bedrock Cross-Region Inference](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference.html)
+
+**限制条件:**
+当前 Gateway 只添加了对 Claude 3 Haiku/Claude 3 Opus/Claude 3 Sonnet/Claude 3.5 Sonnet 的跨区域调用
+- Claude 3 Haiku
+- Claude 3 Opus
+- Claude 3 Sonnet
+- Claude 3.5 Sonnet
+
+**使用前提:**
+- IAM Policy 有 inference profiles 相关的权限和调用模型的权限 (cloudformation template 中已添加)
+- 对 inference profiles 中定义的模型和区域中都启用模型访问权限
+
+**使用方法:**
+- 在调用模型时设置 modelId 为 inference profile ID, 例如 `us.anthropic.claude-3-5-sonnet-20240620-v1:0`
+
+```bash
+curl $OPENAI_BASE_URL/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $OPENAI_API_KEY" \
+  -d '{
+    "model": "us.anthropic.claude-3-5-sonnet-20240620-v1:0",
+    "max_tokens": 2048,
+    "messages": [

+        "role": "user",
