Open-Weight AI Narrows the Capability Gap, But the Safety Divide Widens

BitcoinWorld Open-Weight AI Narrows the Capability Gap, But the Safety Divide Widens A new report from AI safety nonprofit SaferAI reveals that GLM-5.2, an open-weight model from China’s Z.ai, has nearly closed the capability gap with leading frontier systems like OpenAI’s GPT-5.5 and Anthropic’s Claude Opus 4.7, yet it exhibits a stark absence of safety measures, refusing none of the offensive cyber or dual-use biology tasks it was given.

What the SaferAI Evaluation Found SaferAI’s evaluation, conducted via Z.ai’s public API, found that GLM-5.2 refused zero harmful requests in offensive cyber and dual-use biology benchmarks.

In contrast, Anthropic’s Claude Opus 4.7 refused so consistently that SaferAI could not complete the CyberGym benchmark on it at all. This highlights a critical divergence: the frontier of capability is not the frontier of risk.

The report underscores that while closed models can implement safeguards like classifiers and refusal training, these protections become unenforceable once weights are downloaded and run on private infrastructure.
