OpenAI’s latest AI models have a new safeguard to prevent biorisks

OpenAI says that it deployed a brand new system to watch its newest AI reasoning fashions, o3 and o4-mini, for prompts associated to organic and chemical threats. The system goals to forestall the fashions from providing recommendation that would instruct somebody on finishing up doubtlessly dangerous assaults, in keeping with OpenAI’s security report.

O3 and o4-mini signify a significant functionality improve over OpenAI’s earlier fashions, the corporate says, and thus pose new dangers within the palms of unhealthy actors. In accordance with OpenAI’s inside benchmarks, o3 is extra expert at answering questions round creating sure sorts of organic threats particularly. Because of this — and to mitigate different dangers — OpenAI created the brand new monitoring system, which the corporate describes as a “safety-focused reasoning monitor.”

The monitor, custom-trained to cause about OpenAI’s content material insurance policies, runs on prime of o3 and o4-mini. It’s designed to establish prompts associated to organic and chemical danger and instruct the fashions to refuse to supply recommendation on these subjects.

To determine a baseline, OpenAI had pink teamers spend round 1,000 hours flagging “unsafe” biorisk-related conversations from o3 and o4-mini. Throughout a check wherein OpenAI simulated the “blocking logic” of its security monitor, the fashions declined to answer dangerous prompts 98.7% of the time, in keeping with OpenAI.

OpenAI acknowledges that its check didn’t account for individuals who would possibly strive new prompts after getting blocked by the monitor, which is why the corporate says it’ll proceed to rely partially on human monitoring.

O3 and o4-mini don’t cross OpenAI’s “excessive danger” threshold for biorisks, in keeping with the corporate. Nevertheless, in comparison with o1 and GPT-4, OpenAI says that early variations of o3 and o4-mini proved extra useful at answering questions round growing organic weapons.

The corporate is actively monitoring how its fashions may make it simpler for malicious customers to develop chemical and organic threats, in keeping with OpenAI’s just lately up to date Preparedness Framework.

OpenAI is more and more counting on automated methods to mitigate the dangers from its fashions. For instance, to forestall GPT-4o’s native picture generator from creating baby sexual abuse materials (CSAM), OpenAI says it makes use of a reasoning monitor much like the one the corporate deployed for o3 and o4-mini.

But a number of researchers have raised issues OpenAI isn’t prioritizing security as a lot because it ought to. One of many firm’s red-teaming companions, Metr, mentioned it had comparatively little time to check o3 on a benchmark for misleading conduct. In the meantime, OpenAI determined to not launch a security report for its GPT-4.1 mannequin, which launched earlier this week.
