OpenAI and Anthropic Lock Down AI Models as Chinese Rivals Surpass US Cyberattack Benchmarks

Zubiqo Take
QuoteThreads

“Frontier AI labs are suddenly realizing that open-sourcing autonomous exploit engines was a terrible idea, and now they're desperately trying to lock down capabilities that are already in the wild.”

Executive Summary

  • •OpenAI and Anthropic are severely restricting access to their latest frontier models as autonomous cyberattack capabilities hit critical levels.
  • •Chinese AI models Zhipu GLM 5.3 and DeepSeek V4 Pro have officially surpassed Anthropic's Claude Mythos in vulnerability discovery benchmarks.
  • •The shift forces national security agencies into a new arms race as AI handles up to 90% of the tactical work in state-backed cyberattacks.

Key Developments & Data

OpenAI and Anthropic are actively restricting access to models like GPT-6 Astra, Fable 5.1, and Mythos 5.1 after AI cyberattack capabilities officially reached the highest "critical" threat threshold. Chinese models Zhipu GLM 5.3 and DeepSeek V4 Pro recorded vulnerability discovery success rates of 84.5% and 83.3%, officially surpassing Anthropic's Claude Mythos Preview at 83.1%. OpenAI's GPT-6 Astra achieved a 100% score on ExploitBench and autonomously discovered two previously unknown zero-day vulnerabilities during a recent 20-vulnerability evaluation. Anthropic disclosed that a Chinese-backed hacking group recently targeted 30 global organizations using "Claude Code," with the AI handling 80-90% of the tactical work without human intervention. South Korea is attempting to catch up by investing in a Naver-led consortium to build two 700 billion parameter MoE models, backed by 4,000 Nvidia B200 GPUs and 256 H200 GPUs.

Zubiqo Strategic Assessment

Primary Impact

National security agencies, critical infrastructure operators, and enterprise cybersecurity vendors facing an influx of AI-automated zero-day exploits.

Strategic Shift

The transition from AI models functioning as theoretical security assistants to autonomous, weaponized agents capable of executing 90% of a cyberattack's tactical lifecycle.

The Ripple Effect

Tier-1 AI labs will likely face strict government export controls on their cybersecurity-capable models, permanently ending the era of fully open-source frontier capabilities.
