Knowledge-Grounded Answer
Learning goals
Compose retrieval and generation while preserving source metadata.
Quick reference: Level 4; advanced; output type grounded_answer; estimated cost: embedding and LLM provider dependent.
Architecture
Text alternative: The graph contains FlowBeads/input, Memory/KnowledgeQuery, LLMBeads/LLMProcess, FlowBeads/output. It accepts public input and returns a public result.
Prerequisites
None.
Connections
- One configured Knowledge Base
Secrets
- One supported LLM secret
Build and run
- Select a Knowledge Base.
- Select an LLM model and secret.
- Run and compare sources with the answer.
Use this fixture in the Test panel:
Knowledge question
What are the main obligations described in the indexed documents?
Expected result
- retrieval results are recorded
- answer uses retrieved context
Open the persisted run and verify the node timeline. Browser sinks appear in the Inspector; public output appears in the run result when enabled.
Side effects and cost
This Braid has no external side effect.
Cost: embedding and LLM provider dependent. DataBraid stores summaries and structured errors, not secret values.
Extensions
- Change the fixture and compare the node-level timeline.
- Add a Data Probe before the final output.
- Save a known-good fixture for regression testing.
