The world of biomolecules in 3D: New possibilities through open-source AI model Boltz-1

A new open-source AI model called Boltz-1 is revolutionizing the prediction of 3D structures of biomolecules. It enables the generation of 3D structures for proteins, RNA, DNA, and small molecules, achieving accuracy comparable to AlphaFold 3. This development opens new possibilities for research and development in various fields, including medicine, agriculture, and materials science.

Boltz-1 is the first publicly accessible and commercially available model to achieve this accuracy in predicting biomolecular structures. It was developed by researchers at MIT and Genesis Therapeutics and is accessible via platforms like Hugging Face. Users can explore and generate various proteins and viruses there. Optimized versions, for example for L4 graphics cards, are also available for faster calculations.

From AlphaFold 2 to Boltz-1: A leap in biomolecule modeling

The prediction of protein structures has made enormous progress in recent years thanks to AI models like AlphaFold 2. AlphaFold 2 already enabled the prediction of millions of protein structures, which has accelerated research in areas such as the development of malaria vaccines and cancer treatments. Boltz-1 builds on this foundation and extends the possibilities to other biomolecules like RNA, DNA, and small molecules.

Functionality and applications of Boltz-1

Boltz-1 processes a list of molecules as input and generates their joint 3D structure. It models both large biomolecules like proteins, DNA, and RNA, as well as small molecules, called ligands, which include many drugs. In addition, Boltz-1 can also model chemical modifications of these molecules, which control the healthy function of cells and can lead to diseases if disrupted.

The architecture of Boltz-1 is based on an improved Evoformer module, a deep-learning architecture that already underpinned the performance of AlphaFold 2. After processing the inputs, Boltz-1 uses a diffusion network, similar to that of AI image generators, to create its predictions. This process begins with a cloud of atoms and converges over many steps to the final, most accurate molecular structure.

The accuracy of Boltz-1 in predicting molecular interactions surpasses all existing systems. As a single model that calculates entire molecular complexes holistically, it is able to unify scientific findings. This ability is particularly important for drug development, as it allows for the prediction of interactions between proteins and ligands, as well as between antibodies and their target proteins.

Open access and responsible use of AI in biology

The availability of Boltz-1 as an open-source model underscores the importance of open access to scientific tools. This allows researchers worldwide, regardless of their resources and expertise in machine learning, to benefit from the advances in AI-driven biomolecule modeling.

At the same time, the responsible use of this technology is crucial. The developers of Boltz-1 have already collaborated with experts in biosecurity, research, and industry before the model's release to assess and minimize potential risks. Continued collaboration with the scientific community and policymakers is essential to ensure the responsible development and application of AI technologies in biology.
