The Solution:
  • This course gives you the tools, patterns, and code to monitor, debug, and optimize every LLM call in your stack.
What You'll Build:
  • Production-ready observability pipelines with Langfuse
  • Semantic caching systems that reduce costs by 30-50%
  • Smart model routing that automatically selects the cheapest model for each task
  • Alert systems that catch cost spikes before they become budget crises
  • Debug workflows that identify issues in minutes, not hours
