AI evaluation cases generated from production incidents

A software development blog post details a new method for generating evaluation cases for large language models by automatically converting production incidents into test cases. This approach contrasts with traditional hand-written evaluations, which often miss novel failure modes. By capturing the exact input and desired output from postmortems, the system creates relevant test cases that catch regressions and reflect real-world system failures. AI

IMPACT This method could significantly improve the reliability and robustness of LLM deployments by ensuring evaluations reflect actual failure modes.

RANK_REASON The item describes a novel methodology for improving AI model evaluation, which is a research-oriented topic within AI development. [lever_c_demoted from research: ic=1 ai=1.0]

    We stopped writing eval cases by hand. Now every prod incident becomes one.

    <p>TL;DR: Hand-written eval cases test the failures you already imagined, which are never the ones that page you. The best eval cases we have did not come from a brainstorm, they came from production incidents. We wired the postmortem process to emit an eval case automatically, a…
