  • Gemini 4 HydrogenIn its training data
  • Grok 4.7In its training data

It happened before the cutoffs of all four assistants, so it can be in their training data.

Key facts

  • CASP14 results announced 30 November 2020
  • Median GDT of 92.4 across all targets
  • Nature paper and open-source code published July 2021
  • AlphaFold Protein Structure Database (with EMBL-EBI) launched July 2021; expanded to 200M+ structures in 2022
  • Led to the 2024 Nobel Prize in Chemistry for Hassabis and Jumper

What happened

Using an attention-based architecture (Evoformer) trained on known structures, AlphaFold 2 predicted 3D protein structures from amino-acid sequence with near-experimental accuracy.

Why it matters

The clearest case of AI producing a major scientific breakthrough; used by millions of researchers and recognized with a Nobel Prize.
