How to Enable Prompt Caching with Amazon Bedrock

Bedrock allows Claude models to cache tool payloads, system messages, and chat messages between requests. Enable this behavior by adding promptCaching: true under defaultCompletionOptions in your model configuration.
config.yaml
models:
  - name: <MODEL_NAME>
    provider: bedrock
    model: <MODEL_ID>
    defaultCompletionOptions:
      promptCaching: true
Prompt caching is not supported in JSON configuration files, so use the YAML syntax above to enable it.

How to Set Up Authentication for Amazon Bedrock

Authentication will be through temporary or long-term credentials in ~/.aws/credentials under a configured profile (e.g. “bedrock”). 
[bedrock]
aws_access_key_id = abcdefg
aws_secret_access_key = hijklmno
aws_session_token = pqrstuvwxyz # Optional: means short term creds.
You can also use an AWS accessKeyId and secretAccessKey for authentication instead of a local credentials profile.
config.yaml
models:
  - name: <MODEL_NAME>
    provider: bedrock
    model: <MODEL_ID>
    env:
      region: us-east-1
      accessKeyId: ${{ secrets.AWS_ACCESS_KEY_ID }} # can also enter key inline here for local assistants
      secretAccessKey: ${{ secrets.AWS_SECRET_ACCESS_KEY }} # can also enter key inline here for local assistants
    roles:
      - chat
