881-FrontierScience: Benchmarking Expert AI in Science
OpenAI has introduced FrontierScience, a new benchmark designed to measure high-level scientific reasoning in AI models across physics, chemistry, and biology. The system features two distinct tracks: the Olympiad set, which uses complex short-answer problems created by international medalists, and the Research set, which consists of PhD-level sub-tasks. To evaluate these open-ended research problems, the authors implemented a granular rubric-based architecture that assesses intermediate reasoning steps rather than just final answers. Initial testing shows that while top models like GPT-5.2…
