intermediate Published 5 Apr 2026
Action Steps
  1. Build a state schema using LangGraph to define the structure of your AI agent's data
  2. Create nodes and edges in LangGraph to represent the agent's decision-making process
  3. Implement checkpointing to save and load the agent's state for efficient deployment
  4. Apply human-in-the-loop patterns to enable human oversight and feedback in the agent's decision-making process
  5. Configure streaming to enable real-time data processing and updates in the agent
  6. Analyze production cost data from deployed systems to optimize the agent's performance and scalability
