Summary

Hugging Face discovered that frontier AI models (the most advanced commercial AI systems) have safety controls so strict they blocked the company's security team from analyzing attack logs during a breach investigation, even though analyzing malicious payloads is essential for incident response. The company solved this by switching to GLM 5.2, an open-weight model (a freely available AI model anyone can download and run) running on their own servers, which allowed them to conduct forensic analysis without safety restrictions blocking legitimate security work.

Solution / Mitigation

Hugging Face's security team used GLM 5.2, an open-weight model deployed on their own infrastructure, to perform the forensic analysis of intrusion logs instead of relying on frontier models behind commercial APIs. According to their incident report: "We ran the forensic analysis instead on GLM 5.2, an open-weight model, on our own infrastructure. This had a second benefit: no attacker data, and none of the credentials it referenced, left our environment."
