Anthropic finds a Chinese open-weight model can build working cyber exploits
Anthropic's Frontier Red Team said the Zhipu-made open model matched its own frontier model at developing exploits, and that stripping its safety training cost as little as $1,200.

Z.ai and Concordia AI propose staged release rules for risky open-weight models
The framework sorts models into green, yellow or red release zones and cites Z.ai's own two-week delay of GLM-5.3's public weights as a working example of staged release.

Z.ai says GLM-5.3 built much of its own inference stack
The company said an agent built on its own model tripled inference throughput on a 100,000-chip domestic cluster within two weeks, while insisting humans kept control of objectives and risk.

Zhipu releases GLM-5.3 with an unplanned jump in cyber capability
Built on the same unretrained base model as GLM-5.2, it scored 84.5% on the CyberGym vulnerability-discovery benchmark and had its weights withheld for roughly two weeks.
