@tailored-ai/provider-bedrock

AWS Bedrock model provider for Tailored AI agents. One provider id (bedrock) gives your agents every model your AWS account can invoke: Anthropic Claude, Amazon Nova, Meta Llama, Mistral, and the rest of the Bedrock catalog, all through Bedrock's Converse API with full tool-calling support.

Install

tai plugin install @tailored-ai/provider-bedrock

Configure

plugins:
  - "@tailored-ai/provider-bedrock"

providers:
  bedrock:
    defaultModel: "us.anthropic.claude-haiku-4-5-20251001-v1:0"
    region: us-west-2        # optional: falls back to AWS_REGION / profile config
    profile: my-profile      # optional: falls back to the default credential chain

agent:
  defaultProvider: bedrock

You can also select it per agent instead of globally:

agents:
  researcher:
    provider: bedrock
    model: "us.amazon.nova-pro-v1:0"

Credentials

No keys go in config.yaml. The provider uses the standard AWS credential chain: environment variables (AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY), ~/.aws/credentials and ~/.aws/config profiles, SSO sessions, and instance roles. Set profile to pin a named profile; otherwise the default chain applies.

The IAM principal needs bedrock:InvokeModel and bedrock:InvokeModelWithResponseStream on the models you use — the provider streams responses (ConverseStream) whenever the consumer asks for it, falling back to blocking Converse otherwise. Verify access from the same machine with:

aws sts get-caller-identity
aws bedrock list-foundation-models --region us-west-2

Model ids and inference profiles

Most current models on Bedrock require a cross-region inference profile id rather than the bare model id. If you see Invocation of model ID ... with on-demand throughput isn't supported, prefix the id with your region group:

| Bare model id | Use instead | |---|---| | anthropic.claude-haiku-4-5-20251001-v1:0 | us.anthropic.claude-haiku-4-5-20251001-v1:0 | | amazon.nova-pro-v1:0 | us.amazon.nova-pro-v1:0 |

(eu. / apac. for accounts homed in those region groups.) List what your account can invoke:

aws bedrock list-inference-profiles --region us-west-2 \
  --query 'inferenceProfileSummaries[].inferenceProfileId'

Extra request fields

ChatParams.extra (for example an agent's providerExtra settings) passes through as Converse's additionalModelRequestFields, so model-family-specific knobs like Anthropic's top_k reach the model unchanged.

Development

pnpm --filter @tailored-ai/provider-bedrock run build
pnpm --filter @tailored-ai/provider-bedrock run test

The package is a register(ctx) plugin: the default export registers the bedrock provider factory on ctx.providers. The providers.bedrock config shape is owned here; core treats it as an opaque bag.
