The UK Artificial Intelligence Safety Institute and the U.S. Artificial Intelligence Safety Institute conducted a joint pre-deployment evaluation of OpenAI's o1 model. This collaborative assessment represents an official safety evaluation before the model's release.

The UK Artificial Intelligence Safety Institute (UK AISI) and the U.S. Artificial Intelligence Safety Institute (US AISI) conducted a joint pre-deployment evaluation of OpenAI’s latest model, o1 (released December 5, 2024).
The following is a high-level overview of the evaluations conducted, as well as a snapshot of the findings from each domain tested. A more detailed technical report can be found here.
To assess the model’s relative capabilities and evaluate the potential real-world impacts of o1 across these areas, US AISI and UK AISI compared its performance to a series of similar reference models: OpenAI’s o1-preview, OpenAI’s GPT-4o, and both the upgraded and earlier version of Anthropic’s Claude 3.5 Sonnet.
US AISI and UK AISI conducted testing during a limited period of pre-deployment access to the o1 model. Testing was conducted by expert engineers, scientists, and subject matter specialists from staff at both Institutes, and the findings were shared with OpenAI before the model was publicly released.
US AISI and UK AISI ran separate but complementary tests to assess the model’s capabilities across three domains: (1) cyber capabilities , (2) biological capabilities , (3) and software and AI development .
These comparisons are intended only to assess the relative capability improvements of o1, in order to improve scientific interpretation of evaluation results.
This joint evaluation by UK and U.S. safety institutes highlights the growing role of government oversight and international collaboration in assessing advanced AI models before public deployment.
