GLM-5.2 Narrows AI Gap to Months, Refuses 0 Offensive Cyber and Bio Tasks

Summary
SaferAI found Z.ai’s open-weight GLM-5.2 is only a few months behind OpenAI GPT-5.5 and Anthropic Claude Opus 4.7 on cyber and biology benchmarks, yet it refused none of the offensive tasks tested.
That contrast was sharpest against Claude Opus 4.7, which refused so consistently that SaferAI could not complete the CyberGym cybersecurity benchmark on it at all.
Open-weight release makes the risk harder to contain because any API safeguards can be removed once users run the model locally; SaferAI said Z.ai published no safety framework, pre-deployment testing commitments or risk assessment.
The report lands as AI developers lean on refusal training, classifiers and API controls that jailbreaks already bypass on closed models, while open-weight advocates argue the same capabilities can help defenders spot and stop attacks.
