from line 146
146146Invocation of model ID anthropic.claude-sonnet-4-5-20250929-v1:0 with on-demand throughput isn't supported. Retry your request with the ID or ARN of an inference profile that contains this model.

149To invoke these models, pass an inference profile instead of the base model ID. The inference profile ID is the base model ID with a prefix from a column marked "Yes" in the following table, for example us.anthropic.claude-sonnet-4-5-20250929-v1:0. You can also pass the full inference profile ARN, in the form `arn:aws:bedrock:{region}:{account-id}:inference-profile/{inference-profile-id}`. For AWS's authoritative list of available inference profiles, see [Supported Regions and models for inference profiles](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles-support.html). To learn how the prefixes affect routing and pricing, see the [Global versus regional endpoints](https://platform.claude.com/docs/en/build-with-claude/claude-on-amazon-bedrock-legacy#global-vs-regional-endpoints) section.
