In a significant breakthrough for biomedical research and drug development, scientists at the Massachusetts Institute of Technology (MIT) have introduced an innovative open-source AI model named Boltz-1.
This powerful tool accelerates understanding biomolecular structures, a critical aspect of developing new drugs and therapies.
Developed by researchers at the MIT Jameel Clinic for Machine Learning in Health, Boltz-1 marks a pivotal milestone as the first fully open-source model that rivals the advanced capabilities of Google’s AlphaFold3.
This new model promises to democratize access to cutting-edge tools in structural biology, enabling researchers around the globe to collaborate and advance scientific knowledge.
Leading the development of Boltz-1 were MIT graduate students, Jeremy Wohlwend and Gabriele Corso, alongside Saro Passaro, a research affiliate at the Jameel Clinic, and esteemed MIT professors Regina Barzilay and Tommi Jaakkola.
AI model
Wohlwend expressed the ambition behind Boltz-1, stating, “We hope for this to be a starting point for the community. We chose the name Boltz-1 to signify that this is not the end of the line. We are eager for contributions from researchers around the world.”
The role of proteins in biological processes cannot be overstated; their shape directly influences their function.
Thus, predicting and understanding protein structure is vital for designing new drugs and engineering proteins for specific uses.
However, the complex folding process of amino acid chains into 3D structures has been challenging for researchers for many years.
DeepMind’s earlier models, like AlphaFold2—whose creators were awarded the 2024 Nobel Prize in Chemistry—have made significant strides in accurately predicting protein structures.
However, criticisms arose when AlphaFold3, which builds upon AlphaFold2 by incorporating a generative AI model, was only partially open-source and commercially available.
This prompted the scientific community to seek alternative solutions, leading to the development of AI-based Boltz-1.
Improving drug discovery
The MIT team began by replicating the foundational approach of AlphaFold3 AI.
They then delved into the underlying generative diffusion model, identifying enhancements that improved accuracy and efficiency.
The result is not only the documentation of the model but also the entire pipeline for training and fine-tuning Boltz-1, which the team has made available for other scientists to utilize and build upon.
Regina Barzilay, a professor and member of the development team, praised her colleagues’ dedication, saying, “I am immensely proud of everyone involved in bringing Boltz-1 to fruition. This project demanded countless hours of hard work, and we are excited about exploring further improvements in the future.”
The journey to develop Boltz-1 had its challenges. Wohlwend noted that navigating the ambiguity in data from the Protein Data Bank—a comprehensive repository of biomolecular structures—required extensive domain knowledge and perseverance.
Yet, their rigorous experimentation confirmed that Boltz-1 achieves accuracy levels comparable to AlphaFold3 across various complex molecular predictions.
Peer recognition for the project has been overwhelmingly positive.
Biomedical research
Tommi Jaakkola hailed the team’s achievements, stating, “What they’ve accomplished is remarkable. Their hard work will make biomolecular structure prediction more accessible and will revolutionize advancements in molecular sciences.”

The team is committed to improving Boltz-1, streamlining prediction times, and enhancing its capabilities. They encourage researchers to explore the model through its GitHub repository and engage with fellow users via Slack.
Mathai Mammen, CEO of Parabilis Medicines, praised Boltz-1 as a “breakthrough” model.
He explained that by open-sourcing their advancements, the MIT team democratizes essential structural biology tools, which could significantly expedite the development of transformative medicines.
As researchers look to the future, Wohlwend stated, “There are many years of work ahead to enhance these models. We are excited to collaborate and see how the community utilizes this tool.”
With the launch of Boltz-1, the MIT team has made strides in science and set the stage for collaborative innovation in biomedical research.
