Open-weight models are catching up to the frontier, but safety isn't keeping pace

Open-weight AI models are catching up to the frontier. The safety gap remains.

A new SaferAI report evaluated Z.ai's open-weight GLM-5.2 and found its capabilities are closing in on frontier closed models like OpenAI GPT-5.6 Sol and Anthropic Mythos. The model scored 'high risk' across cybersecurity, bio, persuasion, and autonomy, yet ships without matching safeguards. The report renews the worry that powerful open models are outpacing governance and safety mitigations.

Why it matters: SaferAI's safety evaluation of GLM-5.2 brings concrete risk ratings across multiple dimensions—not just opinion. The finding that open-weight models are nearing frontier capability is newsworthy on its own. Score stays at 78 rather than higher because this is a third-party rep...
