AI BriefingOpenAI o3 and o4-mini System Card Addendum: OpenAI o3 Operator
Key point
OpenAI is upgrading Operator, previously based on GPT-4o, to run on the o3 model.
Details
In January 2025, OpenAI released Operator, a Computer Using Agent (CUA) model that browses the web and performs tasks on behalf of users, as a research preview.
The existing GPT-4o-based Operator model will be replaced with an o3-based version. However, the API version will remain the same as before, 4o.
o3 Operator uses the same layered safety approach as before, and has been fine-tuned with additional safety data specifically tailored to computer-use environments. Through this, the model learns the boundaries for task approval and refusal decisions.
o3 Operator inherits o3's coding capabilities, but does not have native access to coding environments or the Terminal.
