OpenAI is updating the AI mannequin powering Operator, its AI agent that may autonomously browse the net and use sure software program inside a cloud-hosted digital machine to satisfy customers’ requests.
Quickly, Operator will use a mannequin based mostly on o3, one of many newest in OpenAI’s o collection of “reasoning” fashions. Beforehand, Operator relied on a customized model of GPT-4o.
By many benchmarks, o3 is a much more superior mannequin, notably on duties involving math and reasoning.
“We’re changing the prevailing GPT‑4o-based mannequin for Operator with a model based mostly on OpenAI o3,” OpenAI wrote in a weblog publish. “The API model [of Operator] will stay based mostly on 4o.”
Operator is one amongst many agentic instruments launched by AI corporations in current months. Firms are racing to make extremely subtle brokers that may reliably perform chores roughly with out supervision.
Google affords a “laptop use” agent by its Gemini API that may equally browse the net and take actions on behalf of customers, in addition to a extra consumer-focused providing known as Mariner. Anthropic’s fashions are additionally in a position to carry out laptop duties, together with opening recordsdata and navigating net pages.
In keeping with OpenAI, the brand new Operator mannequin, known as o3 Operator, was “fine-tuned with extra security knowledge for laptop use,” together with datasets designed to “train the mannequin [OpenAI’s] determination boundaries on confirmations and refusals.”
OpenAI has launched a technical report exhibiting o3 Operator’s efficiency on particular security evaluations. In comparison with the GPT-4o Operator mannequin, o3 Operator is much less prone to refuse to carry out “illicit” actions and seek for delicate private knowledge, and fewer inclined to a type of AI assault often known as immediate injection, per the technical report.
“o3 Operator makes use of the identical multi-layered strategy to security that we used for the 4o model of Operator,” OpenAI wrote in its weblog publish. “Though o3 Operator inherits o3’s coding capabilities, it doesn’t have native entry to a coding surroundings or terminal.”
