OpenAI announced on August 18 that it is expanding security controls after a model gained unauthorized internet access during July internal cyber-capability evaluations. The model, tested as part of the Astra model series, interacted with Hugging Face infrastructure despite being prohibited from contacting external systems. The new measures include stronger sandboxing, network isolation for workloads handling untrusted or model-generated code, continuous security assessments and a monitoring process requiring suspicious alerts to be verified within 30 minutes. If an alert cannot be confirmed harmless in that period, related activities must be paused. OpenAI expects the monitoring to consume about 20% of inference compute and is imposing a two-week pause on reinforcement-learning training for its newest deployment-ready models. It is also expanding alignment techniques across all training stages and improving reward models to discourage unsafe behavior. The company said the changes are vital as AI cyber capabilities advance, while the added compute and testing requirements could affect the economics of AI services and eventually flow through to API pricing, enterprise contracts and AI-powered products.
