The Power of ESM3: A Generative Model for Biology
Table of Contents
At its core, ESM3 is a multimodal generative model that reasons across three fundamental biological properties of proteins: sequence, structure, and function. These properties are represented as discrete tokens, allowing the model to process and generate proteins based on complex prompts.
“ESM3 can follow prompts from each of its input tracks,” explains the research team. The model achieves remarkable consistency with prompts, as demonstrated by its high structure prediction confidence (pTM) and fidelity to backbone cRMSD, SS3 accuracy, and SASA Spearman ρ metrics.
Pushing the Boundaries of Protein Design
One of the most striking features of ESM3 is its ability to generate proteins that differ substantially from those found in nature. When prompted, the model shifts toward a more novel design space, creating proteins with unique structures and sequences. for instance, ESM3 has been used to design proteins based on computationally derived symmetric structures, showcasing its ability to innovate beyond natural evolutionary constraints.
The model also excels at solving complex prompts. By combining atomic-level motifs with high-level instructions—such as keywords or secondary structure specifications—ESM3 generates creative solutions that often bear little resemblance to existing proteins. For example, the model designed a serine protease that is 33% smaller than its natural counterpart while maintaining its active site structure—a feat that highlights its potential for compact, efficient protein design.
Applications Across Medicine, Research, and Beyond
The versatility of ESM3 opens doors to a myriad of applications. In medicine, the model could accelerate the development of targeted therapies by designing proteins that bind to specific molecules, such as serotonin or calcium. In clean energy, it could engineer enzymes that optimize biofuel production.
“ESM3 generates creative solutions to a variety of combinations of complex prompts,” notes the research team. As a notable example, the model has successfully designed proteins with unique binding sites for protease inhibitors and Mcl-1 inhibitors, offering new avenues for drug discovery.
A Glimpse into the Future
As ESM3 continues to evolve,its potential to reshape biology is immense. By making biology programmable, this generative model empowers scientists to explore uncharted territories in protein engineering. Whether it’s designing compact enzymes or creating entirely novel proteins, ESM3 is proving that the future of biology is not just about understanding nature—it’s about reimagining it.
| Key features of ESM3 | Applications |
|————————–|——————|
| Multimodal generative model (sequence, structure, function) | Medicine: Targeted drug design |
| High fidelity to complex prompts | Clean energy: Enzyme optimization |
| Novel protein generation beyond natural constraints | Research: Protein engineering |
| Compact protein design (e.g., 33% smaller serine protease) | Biotechnology: Industrial enzymes |
The era of programmable biology has arrived, and ESM3 is leading the charge. As scientists continue to harness its capabilities, the possibilities are as limitless as evolution itself.

ESM3: A Revolutionary Generative Language Model for Protein Design
For billions of years, nature has been the ultimate innovator, crafting proteins through the slow, meticulous process of evolution. These molecular machines, essential to life, have been shaped by random mutations and natural selection, resulting in a vast library of sequences, structures, and functions. Now, scientists are harnessing the power of artificial intelligence to accelerate this process, creating proteins that push the boundaries of what nature has achieved. Enter ESM3,a groundbreaking multimodal generative language model that simulates evolution to design functional proteins far beyond the scope of known biology.
The Language of Proteins
Proteins are the workhorses of biology, performing tasks ranging from catalyzing chemical reactions to transmitting signals within cells. their functions are determined by their sequences—chains of amino acids—and their three-dimensional structures.Over billions of years, evolution has fine-tuned these sequences and structures, creating a “language” of protein biology.
Recent advances in gene sequencing have cataloged billions of protein sequences and millions of structures, revealing patterns that hint at the underlying rules of this language. Researchers have long sought to decode these rules, and now, language models like ESM3 are providing the tools to do so.
ESM3: A Multimodal Evolutionary Simulator
ESM3 is not just another AI model—it’s a frontier generative language model that reasons over the sequence, structure, and function of proteins. By training on tokens generated by evolution,ESM3 can simulate the evolutionary process,generating proteins that are both novel and functional.
The model operates by iteratively sampling sequences, structures, and functions, guided by complex prompts. For example, researchers prompted ESM3 to generate fluorescent proteins, a class of proteins widely used in biological research. The results were astonishing: ESM3 produced a bright fluorescent protein with only 58% identity to known fluorescent proteins. to put this in outlook,naturally occurring fluorescent proteins with similar divergence are separated by over 500 million years of evolution.
How ESM3 Works
ESM3’s architecture is as innovative as its capabilities. It represents sequence, structure, and function as discrete tokens, fusing them within a single latent space. The model uses transformer blocks to process these tokens, with geometric attention allowing it to condition on atomic coordinates. This multimodal approach enables ESM3 to generate proteins that are not only novel but also highly functional.
The model is trained at three scales: 1.4 billion, 7 billion, and 98 billion parameters. As the scale increases, so does its ability to predict masked tokens and generate proteins with high accuracy.
| Key Features of ESM3 | Description |
|————————–|—————–|
| Multimodal Reasoning | Combines sequence, structure, and function into a single model. |
| Iterative Sampling | generates proteins by unmasking positions step-by-step. |
| Scalability | Available in 1.4B, 7B, and 98B parameter versions. |
| Biological Alignment | Highly responsive to prompts, producing functional proteins. |
Simulating 500 Million Years of Evolution
One of ESM3’s most remarkable achievements is its ability to simulate 500 million years of evolution in a fraction of the time.By generating proteins that are far removed from known sequences, ESM3 opens the door to exploring uncharted regions of protein space.For instance, the fluorescent protein generated by ESM3 is not only novel but also functional, demonstrating the model’s ability to bridge vast evolutionary distances.This capability has profound implications for fields like synthetic biology, drug discovery, and biotechnology, where novel proteins could lead to breakthroughs in medicine and industry.
The Future of Protein Design
ESM3 represents a paradigm shift in protein design. By leveraging the power of language models,researchers can now explore the vast landscape of protein biology with unprecedented speed and precision. This technology could revolutionize our ability to design proteins for specific functions, from targeted cancer therapies to environmental remediation.
As the field of AI-driven protein design continues to evolve, models like ESM3 will play a crucial role in unlocking the secrets of biology. By simulating evolution, these models are not just replicating nature—they’re expanding it.
