Learn best practices for building reliable LLM applications in Python using the Anthropic SDK

intermediate Published 4 Jul 2026
Action Steps
  1. Implement structured outputs to handle LLM responses effectively
  2. Configure retries and idempotency to handle errors and duplicates
  3. Prioritize grounding over hallucination to ensure accurate model outputs
  4. Evaluate model output to detect and correct errors
  5. Apply prompt caching to optimize performance and reduce latency
  6. Treat cost and latency as features to optimize application efficiency
