Overview

• Operator, OpenAI's semi-autonomous web-browsing agent, now uses the o3 reasoning model, replacing the previous GPT-4o version.
• The o3 upgrade enhances task success rates, accuracy, and structured outputs, with benchmarks showing significant performance improvements over its predecessor.
• Enhanced safety measures reduce susceptibility to prompt injection attacks and improve compliance with safety protocols for sensitive actions.
• Operator continues to operate in a cloud-hosted virtual browser, maintaining user privacy and security while completing browser-based tasks.
• The upgraded Operator remains in research preview, accessible only to ChatGPT Pro subscribers, with API access still based on GPT-4o for now.
