Study Tips

1. Master token optimization - Tokens are the primary cost driver. Learn context window management, prompt compression, and caching strategies.

2. Understand caching patterns - Semantic caching and prompt caching dramatically reduce costs. Learn when and how to implement each.

3. Learn performance tuning - Master temperature, top-k, top-p parameters. Understand latency-cost tradeoffs and streaming for user experience.

4. Practice monitoring implementation - Set up CloudWatch dashboards, model invocation logging, and X-Ray tracing for GenAI applications.

5. Study cost-performance optimization - Learn to balance model selection, batching, provisioned throughput, and caching for optimal cost-performance.
