Choosing an AI Model Isn't Just a Cost Decision Anymore. It's a Security One.
Cheaper, more capable open-weight AI models are tempting for any team watching AI development costs. A new safety report shows why cost and capability are only half the evaluation, and what the other half looks like. Every team building AI features right now is watching the same two numbers: how capable a model is, and how much it costs to run. A new evaluation from AI safety nonprofit SaferAI is a reminder that those two numbers don't tell you the whole story, and the part they leave out is exactly the part a delivery team ends up owning after launch. The Gap That's Actually Widening SaferAI's report found that GLM-5.2, the open-weight model from China's Z.ai, is only a few months behind OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.7 on cyber and biology-related capability benchmarks . On raw capability, the open-weight gap is closing fast. On safety practices, it's moving the opposite direction. In SaferAI's testing, GLM-5.2 refused non...
