Additional inference parameters that the model supports, beyond the base set of inference parameters that the Converse API supports in the inferenceConfig field. For more information, see the model parameters link below.

Type declaration

  • [prop: string]: DocumentType
credentials?: AwsCredentialIdentity | Provider<AwsCredentialIdentity>

AWS Credentials. If no credentials are provided, the default credentials from @aws-sdk/credential-provider-node will be used.

endpointHost?: string

Override the default endpoint hostname.

maxTokens?: number

Max tokens.

model?: string

Model to use. For example, "anthropic.claude-3-haiku-20240307-v1:0", this is equivalent to the modelId property in the list-foundation-models api. See the below link for a full list of models.

Default

anthropic.claude-3-haiku-20240307-v1:0
region?: string

The AWS region e.g. us-west-2. Fallback to AWS_DEFAULT_REGION env variable or region specified in ~/.aws/config in case it is not provided here.

streamUsage?: boolean

Whether or not to include usage data, like token counts in the streamed response chunks. Passing as a call option will take precedence over the class-level setting.

Default

true
streaming?: boolean

Whether or not to stream responses

temperature?: number

Temperature.

topP?: number

The percentage of most-likely candidates that the model considers for the next token. For example, if you choose a value of 0.8 for topP, the model selects from the top 80% of the probability distribution of tokens that could be next in the sequence. The default value is the default value for the model that you are using. For more information, see the inference parameters for foundation models link below.
