Amazon Holds Mandatory Engineering Meeting After AI-Assisted Code Causes 'High Blast Radius' Outages

Amazon has mandated that junior engineers can no longer push AI-generated code without senior sign-off, after a series of production incidents traced to generative AI tooling caused significant damage to internal systems.

Amazon convened a mandatory company-wide engineering meeting this week to address a growing pattern of production incidents directly attributed to AI-assisted code changes, according to multiple reports. The incidents were described internally as having "high blast radius" — Amazon's term for failures that cascade across systems — and were explicitly linked to what the company calls "Gen-AI assisted changes," as @lukOlejnik first reported.

The most striking detail: junior engineers at Amazon can no longer push AI-assisted code to production without senior engineer sign-off. It's a remarkable policy reversal for a company that has aggressively promoted AI coding tools internally, and it signals that the gap between AI-generated code that *looks* correct and code that *behaves* correctly in complex production environments is wider than many assumed.
