Open-Source GLM 4.7 Matches Proprietary Models in AI Security Benchmark

AI security

TELUS Digital released a security benchmark in May 2026 showing that open-source AI models can match or exceed the safety performance of proprietary systems. The study included more than 620,000 adversarial tests across 34 models from 10 global providers. These results indicate that AI security is no longer the exclusive domain of closed-source developers.

The GLM 4.7 model, an open-source project from Zhipu AI, was a top performer in the evaluation. This data contradicts the assumption that proprietary architectures are naturally more resistant to attacks. The benchmark used a large-scale testing battery to compare how different systems manage malicious prompts and technical vulnerabilities.

Reasoning Capabilities Drive AI Security

Research data shows a direct link between a model's reasoning logic and its safety profile. Reasoning-focused models had a 19.9% vulnerability rate, while non-reasoning models failed at a rate of 55.1%. This gap suggests that the ability to follow complex, multi-step instructions is a primary defense against security threats.

For enterprise leaders, the performance of GLM 4.7 indicates that open-source transparency is compatible with high safety standards. The study suggests that advanced reasoning logic, rather than a specific licensing model, provides the most effective protection against adversarial manipulation.

The Growing Investment Gap

The report identifies a significant imbalance in how companies fund artificial intelligence. Organizations currently spend $1 on AI security for every $735 spent on general AI development. This spending ratio creates a strategic risk for firms that deploy new technologies without proportional safety measures.

The TELUS Digital benchmark provides a framework for integrating security into the development lifecycle. With open-source models proving effective in adversarial environments, technical leaders are shifting focus toward reasoning-based architectures to defend against digital threats. Future deployments will likely prioritize these logical frameworks over proprietary restrictions.
