The Right Model for the Right Job: Cutting LLM Costs Without Cutting Quality | TestMu 2026
Most AI agents never make it past the demo stage, and the gap between a prototype and a production system comes down to evaluation. I cover how to choose between open source, proprietary, and fine-tuned models, define custom metrics for your use case, calibrate LLM judges for cost-effective assessment, and track results over time to measure real progress. Attendees leave with practical tools to move from proof-of-concept to production.
