OpenAI's GPT-5.4-Cyber is a restricted model fine-tuned for defensive cybersecurity with binary reverse engineering and reduced refusal rates, available only through identity-verified access tiers - a direct response to Anthropic's Mythos Preview.
The Information reports Anthropic is prepping Claude Opus 4.7 and an AI design tool for imminent release, while OpenAI launched GPT-5.4-Cyber yesterday - a restricted cybersecurity model that directly challenges Claude Mythos.
UC Santa Barbara researchers found 9 of 428 third-party LLM routers actively injecting malicious tool calls, draining crypto, and stealing AWS credentials from AI agent sessions.
Claude Mythos Preview is Anthropic's most capable model - restricted to 50 orgs via Project Glasswing, with 93.9% on SWE-bench Verified and thousands of autonomous zero-day discoveries.
A 26B MoE model fine-tuned on elite bug bounty reports and real evasion techniques runs locally in 16.7GB, delivering WAF bypasses, exploit chains, and zero refusals with internal reasoning blocks.
UC Berkeley researchers achieved near-perfect scores on eight major AI agent benchmarks without solving a single task, exposing systemic flaws in how the industry measures progress.
Six million fake stars, $0.06 per click, and a VC funding pipeline that treats GitHub popularity as proof of traction. We ran our own analysis on 20 repos and found the fingerprints.
A suspect linked to the Pause AI movement threw a homemade incendiary at OpenAI CEO Sam Altman's San Francisco home, then threatened to burn the company's headquarters.
Microsoft released the Agent Governance Toolkit, a seven-package open-source system that enforces policies on autonomous AI agents at sub-millisecond latency and covers all 10 OWASP agentic risks.
Anthropic's restricted Claude Mythos Preview model autonomously discovered thousands of high-severity vulnerabilities across every major OS and browser, including bugs hiding in plain sight for 27 years.
Project Glasswing unites AWS, Apple, Google, Microsoft, CrowdStrike, and seven other organizations with $100M in credits for Anthropic's restricted Mythos Preview model to patch critical infrastructure before attackers catch up.
