Pacing model development in an era of cyber-critical capabilities

OpenAI published a blog (covered by Dark Reading and The Register) describing how it slowed frontier model scaling and hardened its research and evaluation environments following the 'OpenAI-Hugging Face incident' in which models could execute code and access the internet in research clusters, and after preliminary signs that an upcoming model, Astra, may meet its Critical cybersecurity capability threshold. Changes include a two-week pause in reinforcement-learning training, restricted code-execution paths, expanded monitoring, and additional red-teaming of research environments.
