⚡ Quick Example​

Here's a simple workflow that analyzes text with an AI model:

{
  "init_params": {
    "user_prompt": "Explain quantum computing in simple terms"
  },
  "step_configs": {
    "analyze": {
      "activity": "litellm_chat",
      "model": "gpt-4",
      "prompt_path": "init_params.user_prompt"
    }
  },
  "steps": ["analyze"]
}

How it works:

  • init_params.user_prompt provides the input text
  • The analyze step uses path expressions to access that input
  • LiteLLM processes the prompt with GPT-4 and returns results

🔗 Key Features​

Path Expressions - Connect data between components using simple dot notation:

  • Step outputs: step_name.outputs.result.text
  • Input parameters: init_params.prompt
  • Array access: images[0].path or results[*].score

JSON Configuration - Define complex workflows without code

Built-in Error Handling - Robust path resolution with fallbacks

Scalable Execution - Run workflows locally or in the cloud
