🔬Beyond AlphaFold: How Boltz is Open-Sourcing the Future of Drug Discovery
February 12, 2026
AI Summary
5 min read🎙️ The Voices & The Context
- The Format: Casual interview with two guests, blending technical deep dives into AI-driven biology with historical context and startup stories.
- The Key Players:
- Gabriela Corso & Jeremy Volgen: Recent MIT PhD grads and co-founders of Boltz (stylized as Volts/Boltz), a public benefit company open-sourcing advanced protein structure prediction and design models to democratize biology tools. Famous for releasing Boltz-1, rivaling AlphaFold 3 shortly after its closed-source debut.
- The Vibe: Educational yet energetic—excited about breakthroughs, optimistic on open science, with humorous asides on compute woes and model "surgery."
🗝️ Key Themes & Topics
The discussion traces AI's revolution in structural biology, from AlphaFold milestones to open-source innovation and practical drug design tools.
- Topic 1: AlphaFold's Breakthroughs & Limits
Explains protein folding basics, CASP competitions, AlphaFold 2's single-chain mastery via evolutionary hints (co-evolution), and AlphaFold 3's leap to multi-molecule interactions (proteins, small molecules, DNA/RNA). Highlights unsolved challenges like dynamics, folding pathways, and novel proteins without evolutionary data.

Show Notes
This podcast features Gabriele Corso and Jeremy Wohlwend, co-founders of Boltz and authors of the Boltz Manifesto, discussing the rapid evolution of structural biology models from AlphaFold to their own open-source suite, Boltz-1 and Boltz-2. The central thesis is that while single-chain protein structure prediction is largely “solved” through evolutionary hints, the next frontier lies in modeling complex interactions (protein-ligand, protein-protein) and generative protein design, which Boltz aims to democratize via open-source foundations and scalable infrastructure.

Key Summary
Evolution of Structure Prediction & Evolutionary Hints
* Co-evolutionary Landscapes: The speakers explain that breakthrough progress in single-chain protein prediction relied on decoding evolutionary correlations where mutations in one position necessitate mutations in another to conserve 3D structure.
* Structure vs. Folding: They differentiate between structure prediction (getting the final answer) and folding (the kinetic process of reaching that state), noting that the field is still quite poor at modeling the latter.
* Physics vs. Statistics: RJ posits that while models use evolutionary statistics to find the right “valley” in the energy landscape, they likely posse
