Optional credentials

credentials?: AwsCredentialIdentity | Provider<AwsCredentialIdentity>

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

Optional endpointHost

endpointHost?: string

Override the default endpoint hostname.

Optional maxTokens

maxTokens?: number

Max tokens.

Optional model

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

Optional region

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.

Optional streamUsage

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

Optional streaming

streaming?: boolean

Whether or not to stream responses

Optional temperature

temperature?: number

Temperature.

Optional topP

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.
