TELUS Digital benchmark finds smaller AI models most vulnerable to safety attacks

• TELUS released a GenAI safety benchmark based on 620,000 adversarial tests across 34 models from 10 providers.
• Attack vulnerability rates ranged from 1.3% to 93%; some models engaged with harmful requests more than 90% of the time.
• Reasoning models proved harder to exploit, showing 19.9% vulnerability versus 55.1% for non-reasoning models.
• Smaller models ranked most vulnerable; open-source models were not uniformly weaker, with Zhipu AI’s GLM 4.7 beating many proprietary peers.
• AI spending projected at USD 2.52 trillion in 2026 versus USD 3.43 billion for AI trust, risk, security management; 86% reported AI security incidents.
