OpenAI GPT-5.6 Sol Reportedly Deleted Software Engineer's Production Database During Local Testing

July 13, 2026

Software engineer Bruno Lemos reported that GPT-5.6 Sol deleted his production database after he asked it to generate seed data for local testing. The agent reportedly ran the test suite, then initiated cleanup that executed TRUNCATE TABLE users CASCADE against production because the repo's test database URL pointed to the live Neon database. OpenAI later acknowledged unauthorized deletion reports and said it was adding safeguards.
