OpenAI unveils FrontierScience, a new benchmark to evaluate AI’s expert-level reasoning in physics, chemistry, and biology, aiming to accelerate scientific research.
OpenAI has introduced FrontierScience, a groundbreaking benchmark designed to assess the capacity of artificial intelligence (AI) in executing expert-level scientific reasoning across various domains such as physics, chemistry, and biology. This initiative aims to enhance the pace of scientific research, as reported by OpenAI.
Accelerating Scientific Research
The development of FrontierScience comes in the wake of significant advancements in AI models, such as GPT-5, which have demonstrated the potential to expedite research processes that typically take days or weeks to mere hours. OpenAI’s recent experiments, documented in a November 2025 paper, highlight GPT-5’s ability to accelerate research endeavors significantly.
OpenAI’s efforts to refine AI models for complex scientific tasks underscore a broader commitment to leveraging AI for human benefit. By enhancing models’ performance in challenging mathematical and scientific tasks, OpenAI aims to provide researchers with tools to maximize AI’s potential in scientific exploration.
Introducing FrontierScience
FrontierScience serves as a new standard for evaluating expert-level scientific capabilities. It comprises two main components: Olympiad, which assesses scientific reasoning akin to international competitions, and Research, which evaluates real-world research capabilities. The benchmark includes hundreds of questions crafted and reviewed by experts in physics, chemistry, and biology, focusing on originality, difficulty, and scientific significance.
In initial evaluations, GPT-5.2 achieved top scores in both the Olympiad (77%) and Research (25%) categories, outperforming other advanced models. This progress highlights AI’s growing proficiency in tackling expert-level challenges, though there remains room for improvement, particularly in open-ended, research-oriented tasks.
Constructing FrontierScience
FrontierScience consists of over 700 text-based questions, with contributions from Olympiad medalists and PhD researchers. The Olympiad section features 100 questions designed by international competition winners, while the Research section includes 60 unique tasks simulating real-world research scenarios. These tasks aim to mimic the complex, multi-step reasoning required in advanced scientific research.
To ensure rigorous evaluation, each task is authored and reviewed by experts, and the benchmark’s design incorporates input from OpenAI’s internal models to maintain a high standard of difficulty.
Evaluating AI Performance
FrontierScience employs a combination of short-answer scoring and rubric-based assessments to evaluate AI responses. This approach allows for a detailed analysis of model performance, focusing not only on final answers but also on the reasoning process. AI models are scored using a model-based grader, ensuring scalability and consistency in evaluations.
Future Directions
Despite its achievements, FrontierScience acknowledges its limitations in fully capturing the complexities of real-world scientific research. OpenAI plans to continue evolving the benchmark, expanding into more areas and integrating real-world applications to better assess AI’s potential in scientific discovery.
Ultimately, the success of AI in scientific research will be measured by its ability to facilitate new scientific discoveries, making FrontierScience an essential tool in tracking AI’s progress in this field.
