AI-Accelerated Vulnerability Discovery

Frontier AI models (GLM-5.3, GPT-5.6 Sol, Mythos) and new specialized models like VulnLLM-R are discovering thousands of novel vulnerabilities at unprecedented speed. Google's AVDH found 100+ critical vulns in 2 days. Anthropic productized Mythos 5 in Claude Security. The disclosure-to-exploit window has collapsed to 'half-day'.
