ScienceOne, also known as Panshi (磐石), is an artificial intelligence platform for scientific research developed by the Chinese Academy of Sciences (CAS) and its Institute of Automation. It can review scientific literature, analyse research data, and select and coordinate specialised software for multistep research tasks.
ScienceOne models are used in fields ranging from mathematics and physics to biology, astronomy, materials science and environmental science.
History ScienceOne was introduced in April 2025. Its initial tools included S1-Literature, a scientific literature assistant, and S1-ToolChain, which coordinates research software. The Panshi scientific foundation model was presented at the World Artificial Intelligence Conference on 26 July 2025. Version 1.5 came out in November 2025 and added tools for evaluating research ideas.
ScienceOne 100 was released in April 2026, bringing the foundation model together with eight field-specific models. In July 2026, CAS released Panshi 2.0.
Features ScienceOne combines general-purpose AI models with models designed for scientific tasks. Its S1-Base models are based on Qwen.
S1-Literature is designed for analysing scientific papers, tracing citations and preparing literature reviews.
Panshi 2.0 brings different types of scientific data into a common representation. Reported uses include predicting chemical properties or inferring molecular structures.
Applications Reported uses include analysing particle-physics experiments, studying materials, processing astronomical observations and modelling fluid flow. According to CAS, the Panshi model system had been deployed across more than 50 of its units by April 2026.
The Shanghai Advanced Research Institute developed ScienceOne–Yuheng, a carbon-accounting system that measures and attributes greenhouse gas emissions.
