WorkflowStep

A workflow step is the atomic unit of logging to Galileo. They represent a single execution of a workflow, such as a chain, agent, or a RAG execution. Workflows can have multiple steps, each of which can be a different type of node, such as an LLM, Retriever, or Tool. You can log multiple workflows in a single request. Each workflow step must have the following fields:
  • type: The type of the workflow.
  • input: The input to the workflow.
  • output: The output of the workflow.

​
Examples

​
LLM Step

{
  "type": "llm",
  "input": "What is the capital of France?",
  "output": "Paris"
}

​
Retriever Step

{
  "type": "retriever",
  "input": "What is the capital of France?",
  "output": [{ "content": "Paris is the capital and largest city of France." }]
}

​
Multi-Step

Workflow steps of type workflow, agent or chain can have sub-steps with children. A workflow with a retriver and an LLM step would look like this: 
{
  "type": "workflow",
  "input": "What is the capital of France?",
  "output": "Paris",
  "steps": [
    {
      "type": "retriever",
      "input": "What is the capital of France?",
      "output": [{ "content": "Paris is the capital and largest city of France." }]
    },
    {
      "type": "llm",
      "input": "What is the capital of France?",
      "output": "Paris"
    }
  ]
}
