OpenAI Deploys o3 Reasoning Model for Scientific Discovery in Par...

OpenAI announced a research partnership with CERN, the European Organisation for Nuclear Research, to deploy its o3 advanced reasoning model to assist physicists in analysing petabytes of data from the Large Hadron Collider. The model has been fine-tuned on a corpus of 200,000 particle physics papers and can generate hypotheses, design experiments, and identify anomalous collision events that human analysts may overlook in the vast data volume. In its first eight weeks of operation, the system flagged 17 anomalous particle interaction signatures for deeper human investigation, three of which are currently under formal review as potential beyond-standard-model phenomena. CERN Director-General Fabiola Gianotti described the partnership as a new paradigm for AI-assisted fundamental science. India Tata Institute of Fundamental Research is listed as a collaborating institution in the partnership.
