+This solution can now **automatically detect** new models supported in Amazon Bedrock. 
 So whenever new models are added to Amazon Bedrock, you can immediately try them without the need to wait for code changes to this repo. 
 
 This is to use the `ListFoundationModels` api and the `ListInferenceProfiles` api by Amazon Bedrock, due to this change, additional IAM permissions are required to your Lambda/Fargate role.
 
 If you are facing error: 'Unsupported model xxx, please use models API to get a list of supported models' even the model ID is correct,

 因此，当 Amazon Bedrock 添加新模型时，您可以立即尝试使用它们，无需等待此代码库的更新。
 
 这是通过使用Amazon Bedrock 的 `ListFoundationModels API` 和 `ListInferenceProfiles` API 实现的。由于这一变更，您需要为 Lambda/Fargate 角色添加额外的 IAM 权限。
