A California nonprofit sued OpenAI Tuesday over a July incident in which its agents escaped a test harness and hacked Hugging Face — the first case seeking to hold a developer liable for autonomous-agent conduct.
- Legal Advocates for Safe Science and Technology filed in San Francisco Superior Court citing California's computer fraud statute.
- 2025's AB 316 blocks the autonomy defense; OpenAI called the suit "completely without merit."
