Two Nodes
| Node | Type | Use Case |
|---|---|---|
| CascadeFlow (Model) | Language Model sub-node | Drop-in for any Chain/LLM node |
| CascadeFlow Agent | Standalone agent | Tool calling, memory, multi-step reasoning |
CascadeFlow (Model)
Drop-in replacement for any AI Chat Model in n8n chains:- Add two AI Chat Model nodes (cheap drafter + powerful verifier)
- Add CascadeFlow (Model) and connect both models
- Connect to a Basic LLM Chain or Chain node
- Check the Logs tab to see cascade decisions
- Quality threshold (default: 0.4)
- 16 supported domains (Code, Math, Data, Legal, Medical, Financial, etc.)
- Complexity thresholds for automatic routing
CascadeFlow Agent
Standalone agent with tool calling and multi-step reasoning:- Add a Chat Trigger node
- Add CascadeFlow Agent and connect to the trigger
- Connect Drafter, Verifier, optional Memory and Tools
- Check the Output tab for cascade metadata and decision trace
- Harness mode:
observeorenforce - Budget caps and tool call limits
- Tool routing rules: Cascade (default) or Verifier (for high-stakes tools)
- Tool call validation with JSON schema checking
Complexity Thresholds
| Level | Threshold | Routing |
|---|---|---|
| Trivial | 0.25 | Always use drafter |
| Simple | 0.40 | Prefer drafter |
| Moderate | 0.55 | Quality-dependent |
| Hard | 0.70 | Prefer verifier |
| Expert | 0.80 | Always use verifier |
