FAQ

Questions about Invoke Model (Raw).

What does the Invoke Model (Raw) action do in AWS Bedrock?

Model-specific Invoke API for cases where the unified Converse API doesn't expose what you need (e.g., specific Claude-only parameters, specific generation modes for image/embedding models). Each model has its own request shape — check Bedrock's per-model docs.

What inputs does Invoke Model (Raw) require?

Required: Model ID, Request Body (JSON). Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if AWS Bedrock returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Invoke Model (Raw) support batch operations?

Yes. Run Invoke Model (Raw) inside a Loop node to process arrays. Tiny Command handles AWS Bedrock's rate limits automatically so you don't have to throttle manually.

Action

Bedrock Converse

The model-agnostic chat API — same message-array shape works across Claude, Llama, Mistral, and other chat-capable Bedrock models. Swap models with a single parameter change. The recommended default for new Bedrock workflows since it abstracts away model-specific request quirks.

Action

Knowledge Bases Retrieve

Semantic-searches a configured Bedrock Knowledge Base (which sits on top of S3-stored documents indexed into a vector store) and returns the most relevant chunks with citations. Saves you from building and managing your own RAG ingestion pipeline.

How do I call a Bedrock model with model-specific parameters?
