Scientists flock to DeepSeek: how they’re using the blockbuster AI model

Repeated tests suggest that DeepSeek-R1’s ability to solve mathematics and science problems matches that of the o1 model, released in September by OpenAI in San Francisco, California, whose reasoning models are considered industry leaders.
Although R1 still fails on many tasks that researchers might want it to perform, it is giving scientists worldwide the opportunity to train custom reasoning models designed to solve problems in their disciplines.
“Based on its great performance and low cost, we believe Deepseek-R1 will encourage more scientists to try LLMs in their daily research, without worrying about the cost,” says Huan Sun, an AI researcher at Ohio State University in Columbus. “Almost every colleague and collaborator working in AI is talking about it.”
Open seasonFor researchers, R1’s cheapness and openness could be game-changers: using its application programming interface (API), they can query the model at a fraction of the cost of proprietary rivals, or for free by using its online chatbot, DeepThink. They can also download the model to their own servers and run and build on it for free — which isn’t possible with competing closed models such as o1.
Since R1’s launch on 20 January, “tons of researchers” have been investigating training their own reasoning models, based on and inspired by R1, says Cong Lu, an AI researcher at the University of British Columbia in Vancouver. That’s backed up by data from Hugging Face, an open-science repository for AI that hosts the DeepSeek-R1 code. In the week since its launch, the site had logged more than three million downloads of different versions of R1, including those already built on by independent users.
Scientific tasksIn preliminary tests of R1’s abilities on data-driven scientific tasks — taken from real papers in topics including bioinformatics, computational chemistry and cognitive neuroscience — the model matched o1’s performance, says Sun. Her team challenged both AI models to complete 20 tasks from a suite of problems they have created, called the ScienceAgentBench. These include tasks such as analysing and visualizing data. Both models solved only around one-third of the challenges correctly. Running R1 using the API cost 13 times less than did o1, but it had a slower “thinking” time than o1, notes Sun.
R1 is also showing promise in mathematics. Frieder Simon , a mathematician and computer scientist at the University of Oxford, UK, challenged both models to create a proof in the abstract field of functional analysis and found R1’s argument more promising than o1’s. But given that such models make mistakes, to benefit from them researchers need to be already armed with skills such as telling a good and bad proof apart, he says.
Much of the excitement over R1 is because it has been released as ‘open-weight’, meaning that the learnt connections between different parts of its algorithm are available to build on. Scientists who download R1, or one of the much smaller ‘distilled’ versions also released by DeepSeek, can improve its performance in their field through extra training, known as fine tuning. Given a suitable data set, researchers could train the model to improve at coding tasks specific to the scientific process, says Sun.
