A silent revolution is taking place in an MIT lab. Here, scientists are using AI to direct their work rather than only conducting experiments. Two new AI models created at MIT, CRESt and BoltzGen, are doing more than just aiding research. They are contributing to the design.
These systems are capable of more than just following commands. They actively suggest what should be tested next. CRESt, which has a very creative structure, functions as a smart assistant that continuously learns from ongoing data and modifies its recommendations. In contrast, BoltzGen provides a very efficient shortcut through the costly maze of real-world testing by simulating potential outcomes in physical systems prior to any construction.
These techniques greatly decreased trial-and-error by fusing deep simulation with reasoning. These models seem especially relevant at a time when many labs are under pressure to generate results more quickly, more affordably, and with more accuracy.
For instance, hundreds of combinations were tested in actual laboratories by a research team investigating sustainable battery materials. They now only assess the best applicants, saving months of work and significantly reducing waste, thanks to CRESt’s improved prompts and BoltzGen’s predictive power.
In the early stages of discovery, when opportunities far exceed available resources, the change is especially advantageous. These tools let scientists learn more quickly, fail more intelligently, and change course sooner during the initial stages, where failure frequently teaches more than success.

MIT has made sure that this technology doesn’t stay behind closed doors by forming strategic alliances and using an open-source design. BoltzGen is already being modified for use in climate modeling and pharmaceutical pipelines by labs in Canada, Singapore, and Germany.
I observed a young researcher halt in the middle of a remark when CRESt presented a counter-hypothesis during a visit last year. Not the concept itself impressed me, but the ease with which it was accepted—as if the AI had merited a place at the brainstorming table.
The culture shift within labs is being accelerated by the normalization of human-machine collaboration. These are not inflexible, command-line programs. By reducing decision trees, improving variables, and getting rid of redundancy with incredibly effective reasoning, they function more like cooperative partners.
BoltzGen has aided in the development of new compounds suited for targeted medicinal therapy by utilizing sophisticated pattern recognition and simulation. These are substances that are now being patented and getting ready for preclinical testing, not hazy proofs-of-concept. The data that come out of these initiatives frequently highlight increased yield, less toxicity, and much quicker prototyping.
These technologies also provide a surprising benefit in the face of growing R&D expenses: they facilitate experimentation. By using these models, labs with little money or personnel can level the playing field and obtain knowledge that is usually only available to large research institutes.
In the last ten years, artificial intelligence has evolved from a lab-only concept to a commonplace tool. However, it feels different at this point. AI is redefining what human tasks should be, not performing them. Not only can these models provide speedier answers, but they also assist ask better questions by producing hypotheses.
MIT is developing a more adaptive approach by incorporating machine learning directly into the beat of experimental science, where each test educates the system, which then enhances each test.
This, of course, raises questions. Can an AI create important experiments that we can trust? What occurs when scholars use automated insight excessively? These are issues related to health. However, it’s increasingly evident that AI is enhancing critical thinking rather than displacing it.
The benefit to medium-sized research teams is time recovery. They can devote more hours to analyzing data, discussing approaches, and honing intuition—skills that are distinctly human—instead of computing derivatives or repeating unsuccessful processes.
The larger scientific community has recently started to view tools like CRESt and BoltzGen more as infrastructure than as experiments in and of themselves. They are starting to be included in the necessary toolbox, much like centrifuges and microscopes. That change is occurring more quickly than many anticipated thanks to open-data standards and incredibly clear user interfaces.
We may look back and see that this was the turning point in research, when it stopped waiting for answers and began creating better questions, by the time these AI models are extensively used in fields like bioengineering and climate science.
