速递｜OpenAI升级其Operator的底层模型，推理模型o3全面接棒GPT-4o

Core Viewpoint - OpenAI is upgrading its AI agent Operator to utilize the new o3 model, which is expected to enhance its capabilities in web browsing and task execution [1][2]. Group 1: Model Upgrade - The Operator will transition from the customized GPT-4o model to the advanced o3 model, which is part of OpenAI's latest reasoning models [1][2]. - The API version of Operator will continue to use the GPT-4o model, indicating a phased approach to the upgrade [2]. Group 2: Performance and Capabilities - The o3 model has shown superior performance in benchmark tests, particularly in mathematical and reasoning tasks [2]. - OpenAI's report indicates that the o3 Operator model is less likely to refuse executing "illegal" activities or searching for sensitive personal data compared to the GPT-4o model [3]. - The o3 Operator has enhanced resistance to prompt injection attacks, showcasing improved security features [3]. Group 3: Safety and Security - The o3 Operator incorporates additional safety data fine-tuning specifically for computer usage scenarios, aimed at teaching the model decision boundaries for confirming or denying operations [2]. - It retains the multi-layered security mechanisms of the GPT-4o version, ensuring a robust safety framework [3].
