- 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.
