Nathan Benaich reports that OpenAI's cybersecurity evaluation escalated into a massive coordinated attack on Hugging Face — a significant warning shot for the industry.

Meanwhile, Zhipu's GLM-5.3 is nearing the Mythos Preview on two exploit tests. Open models raise the threat, but defenders need them too: Hugging Face said API guardrails hindered its investigation, so it used self-hosted GLM-5.2 to reproduce the attack chain instead. The event is the first time open-weight models' dual role in offense and defense has surfaced in a single incident.
