OpenAI Bakes 20% Compute Overhead Into Astra Inference Monitoring
OpenAI now estimates monitoring overhead at roughly 20% of the inference compute being monitored, covering all reinforcement-learning training and evaluations involving tools for GPT-5.6 Sol-class and higher models plus all inference on the Astra model. The figure comes from OpenAI's "Pacing model development in an era of cyber-critical capabilities" post published August 19 by The Register. OpenAI told The Register the costs are internal research spend that will not be passed to customers, though The Register warns that position may be unsustainable if OpenAI goes public. The overhead stems from expanded chain-of-thought monitoring layered on top of workload isolation and red-teaming rolled out after the recent Hugging Face security incident.
