OpenAI’s Operator agent gets a boost with new AI model
The post OpenAI’s Operator agent gets a boost with new AI model appeared on BitcoinEthereumNews.com.
OpenAI updated the AI model powering Operator from the previous custom version of GPT-4o to a model based on o3, one of the latest in OpenAI’s o series of “reasoning” models. The o3 Operator was fine-tuned with additional safety data for computer use and included safety datasets designed to teach the model decision boundaries. OpenAI upgraded the Operator in ChatGPT with a new Computer-Using Agent (CUA) model based on a version of OpenAI o3. With the new model, the Operator became more persistent and more accurate when interacting with the browser, improving the overall task success rate. It also delivers better-structured responses that are more clear and thorough. According to OpenAI, the new CUA model showed stronger performance relative to the industry, achieving SOTA on OSWorld and WebArena. It also showed stronger relative performance to the previous version, both in established benchmarks and human preference evaluations. OpenAI replaces the GPT‑4o-based model with a version based on o3 OpenAI hints at a big upgrade for ChatGPT Operator Agent pic.twitter.com/iGPQp9butD — SabatAge (@sabatage) May 22, 2025 OpenAI replaced the existing GPT‑4o-based model for Operator with a version based on OpenAI o3, although the API version will remain based on 4o. The AI firm also claimed that the o3 Operator uses the same multi-layered safety approach used for the 4o version. However, compared with other models in the o3 family, the o3 Operator was fine-tuned with additional safety data for computer use, including safety datasets designed to teach the model decision boundaries on confirmations and refusals. OpenAI released a technical report showing the o3 Operator’s performance on specific safety evaluations. Compared to the GPT-4o Operator model, the o3 Operator was less likely to refuse to perform “illicit” activities and search for sensitive personal data and less susceptible to a form of AI attack…
