Model upgrades need replay protocol, not just benchmarks

This article proposes a replay protocol for model upgrades, emphasizing reproducibility over benchmark scores. It suggests that before deploying a new model, teams should replay production traffic against it to ensure it meets specific contracts, such as consistent tool-call shapes and termination conditions. The author highlights that free access tiers for models and servers, like those offered by MonkeyCode, remove common excuses for skipping this crucial testing phase. The proposed protocol involves stages like candidate testing, shadow deployment, and canary releases to catch subtle issues that standard evaluations might miss. AI

IMPACT Suggests a critical testing methodology for AI model deployments to ensure stability and prevent subtle contract violations.

RANK_REASON Article proposes a methodology for AI model deployment, not a new release or product.
