OpenAI released a research preview of Computer-Using Agent on Jan 23, 2025, and is exposing it first through Operator to U.S. ChatGPT Pro users. The model combines GPT-4o vision with RL-based reasoning and acts through screenshots, a mouse, and a keyboard; it scored 38.1% on OSWorld, 58.1% on WebArena, and 87.0% on WebVoyager. The key point is API-free GUI control, while sensitive actions still require user confirmation.

OpenAI reports that o1-preview and o1-mini often drive adversarial attack success rates close to zero as inference-time compute increases. The paper tests math tasks, SimpleQA prompt injection, Attack Bard images, and StrongREJECT misuse prompts; it labels the result as preliminary, and the truncated post does not fully disclose all failure cases. The key point is that this gain comes from longer reasoning at inference, not adversarial training.
