LLM Workflow Patterns for Production

By PROTYPAI Team

Common Workflow Patterns

1. Chain Pattern

Sequential LLM calls where each output feeds into the next step. Useful for multi-stage processing like research → summary → action.

2. Router Pattern

A decision-making LLM routes requests to specialized handlers. Enables modular architecture with focused sub-systems.

3. Parallel Pattern

Multiple LLM calls executed concurrently and merged. Improves latency for independent operations.

4. Human-in-Loop Pattern

LLM output requires human approval before action. Critical for high-stakes decisions or regulated industries.

Best Practices

  • Always implement timeouts and circuit breakers
  • Handle rate limits gracefully with exponential backoff
  • Log all LLM interactions for debugging and monitoring
  • Implement retry logic with jitter for reliability
  • Monitor token usage and costs in real-time
  • Version all prompts and track performance changes
