View Source LangChain.Utils.BedrockConfig (LangChain v0.3.1)
Configuration for AWS Bedrock.
Examples
For applications hosted in AWS, ExAws caches
temporary credentials (when running on AWS), so in the credentials function
you can pull the current cached credentials from ExAws
.
ChatAnthropic.new!(%{
model: "anthropic.claude-3-5-sonnet-20241022-v2:0",
bedrock: %{
credentials: fn ->
ExAws.Config.new(:s3)
|> Map.take([:access_key_id, :secret_access_key])
|> Map.to_list()
end,
region: "us-west-2"
}
})
For applications hosted anywhere, you can configure the Bedrock settings into
the LangChain config like this (recommended for config/runtime.exs
):
config :langchain,
aws_access_key_id: System.fetch_env!("AWS_ACCESS_KEY_ID"),
aws_secret_access_key: System.fetch_env!("AWS_SECRET_ACCESS_KEY"),
aws_region: System.get_env("AWS_REGION", "us-west-1")
Then, when you want to later use a Bedrock Anthropic model, this is will load it:
ChatAnthropic.new!(%{
model: "anthropic.claude-3-5-sonnet-20241022-v2:0",
bedrock: BedrockConfig.from_application_env!()
})
