# AI Routing

> Stage-based provider routing and common configuration patterns

Insight Flow splits content processing into multiple stages. Each stage can choose its own execution provider so you can balance cost, speed, and output quality.

## Stage Model

* `filter`: remove low-value or irrelevant items
* `keywords`: extract keywords
* `global_summary`: generate a summary across multiple items
* `report`: generate the final report body

## Available Providers

* `rule`: rule-based execution
* `llm_openai`: OpenAI-compatible model execution
* `llm_codex`: Codex-compatible model execution

Notes:

* `global_summary` and `report` only support LLM providers
* Check defaults through `GET /api/v1/monitors/ai-routing/defaults`

## How to Use It

1. Configure and test providers on the Providers page
2. Create or edit a monitor
3. Choose a provider for each stage
4. Run a small monitor first to compare latency and output quality

## Common Patterns

* Cost-first: `filter=rule`, `keywords=rule`, `global_summary=llm_openai`, `report=llm_openai`
* Single-model: all LLM stages use `llm_codex`
* Hybrid: rules for lightweight stages, LLMs for long-form output
