From Prototype to Production: Evaluating AI Products with Aman Kahn: ProductTank SF
In this Product Tank SF talk, AI product strategist Aman Kahn breaks down how product teams can move from prototyping AI agents to confidently shipping them. Drawing on experience at Cruise, Spotify and now Arize, Aman outlines a practical framework for observability and evaluation (eval) of LLM-powered products.He demonstrates how PMs can use traces and spans to understand agent behaviour, build evaluation workflows using LLMs as judges, and align cross-functional teams around quality metrics. No code needed.

Key takeaways
Observability is foundational to AI product development
System-level evals matter more than model benchmarks
PMs can lead eval strategy without deep technical skills
Start small with real data — iterate before you scale
Use LLMs to label data, but always verify with humans
Evaluation is continuous and works both offline and online
Discrete labels (e.g. correct/incorrect) work better than scoring
Strong evals come from cross-functional collaboration Receive SMS online on sms24.me
