Foundation Models

Introduction: The Convergence Point In Post 13, we defined agentic AI as systems that autonomously plan, reason, use tools, and execute multi-step scientific workflows. Now we arrive at the central thesis of this entire series: Agentic Omics — the convergence of large language model (LLM) reasoning with domain-specific biological AI models like AlphaFold, ESM, scGPT, and DNABERT to create autonomous systems capable of end-to-end biological discovery. This is not science fiction. As of early 2026, agentic systems are being deployed in operational drug discovery settings at companies like AstraZeneca, with documented implementations compressing workflows that once took months into hours while maintaining scientific traceability (Seal et al., 2025). The question is no longer if this convergence will transform biology, but how — and what architecture will get us there most reliably. ...

The genome is the ultimate source code. For decades, computational biologists have relied on alignment algorithms, hidden Markov models, and specialized machine learning to decode it. Today, a new paradigm is taking hold: DNA foundation models. By treating the genome as a vast, continuous text and training large language models (LLMs) on billions of nucleotides, researchers are teaching AI to “read” the book of life in its native language. In this fifth installment of our Agentic Omics series, we examine the state of the art in genomic AI. We explore how models like DNABERT-2, Nucleotide Transformer, Evo, and HyenaDNA are moving beyond sequence classification to predict gene expression, identify regulatory elements, and quantify variant effects. Crucially, we will dissect the architectural innovations that make this possible—and the biological complexities that still confound these models. ...

Welcome back to Agentic Omics: When AI Reads the Book of Life. In our first post, we mapped the complex, multi-layered territory of modern biological data. We saw that while fields like metabolomics are still wrangling with extreme chemical complexity, disciplines defined by sequences—genomics, transcriptomics, and proteomics—are experiencing a massive influx of AI-ready data. But data alone isn’t enough. The true catalyst of the current biological AI revolution is a specific architectural breakthrough originally designed to translate English to French: the Transformer. ...
