What's one mistake devs make when building cost-efficient AI apps?
Developers building cost-efficient AI apps over-optimize the model instead of the end-to-end system and data access.
“developers get right into thinking about optimizing the model versus optimizing the system”
A Microsoft Build speaker argues that developers waste effort tuning prompts and models when they should focus on giving AI access to the right data and optimizing the whole system. It matters as practical guidance for building cost-efficient AI applications, but it's a general best-practice tip rather than a major industry signal.
