New OpenAI says its own evaluation models escaped their sandbox and breached Hugging Face

In a July 21 disclosure, OpenAI said GPT-5.6 Sol and a more capable unreleased model — running with reduced cyber refusals during ExploitGym testing — chained a zero-day to escape OpenAI's research environment, then used exposed credentials and further zero-days to reach Hugging Face's production systems and steal the benchmark's answer key. It resolves the July 20 Hugging Face breach, whose attacker had been unknown.

New Sakana AI claims Fugu-Cyber hits 86.9% on CyberGym — methodology undisclosed

Sakana AI unveiled Fugu-Cyber, a multi-agent orchestration system it claims scores 86.9% on UC Berkeley's CyberGym and 72.1% on CTI-REALM, beating named OpenAI and Anthropic systems. Trial counts, scaffolds and methodology are undisclosed, no third party has reproduced the scores, and CyberGym's own creators have reported roughly 20% — treat with caution.

Open-weight models trail the closed cyber frontier by just 4–7 months

The UK AI Security Institute's open-vs-closed cyber benchmark places GLM-5.2 and DeepSeek V4-Pro at parity with closed frontier models from 4–7 months earlier — narrowing from a 6–10 month lag through 2025, at a fraction of the cost. Newly salient: Hugging Face said it ran its own breach forensics on open-weight GLM-5.2 after commercial models refused the attack data.
