~1 min readEpoch AI has charted the massive spike in reported security vulnerabilities. In June 2026, 21 organizations reported about 1,500 high-severity and critical vulnerabilities (CVEs), more than 3.5 times the previous monthly record.

The spike follows Anthropic's announcement in April that its model Claude Mythos Preview can find software vulnerabilities on its own. According to Anthropic, trusted partners were already using the model to find and fix bugs before its release. Anthropic's "Glasswing" program has reportedly uncovered more than 10,000 high-severity or critical vulnerabilities so far, some of which haven't been published yet. OpenAI's "Daybreak" program is likely adding to the surge as well. Epoch AI says the jump in reported vulnerabilities reflects a wave of AI-driven discoveries.

An AI model programmed nonstop for 19 days on a single MirrorCode task that cost $2,600 to run
Epoch AI's MirrorCode benchmark reveals Claude Opus 4.7 as the leader with a 56% solve rate, reconstructing a 16,000-line toolkit in 14 hours. Despite this, all models tested struggle with the most complex tasks, highlighting limitations in current AI capabilities. The single task consumed $2,600 over 19 days, raising questions about cost-effectiveness in AI development.
