I’d like to introduce an example where AlphaFold version 2 is open source, but version 3 is closed source.

AlphaFold 2 (Open Source)

AlphaFold 2’s open source code is published at https://github.com/google-deepmind/alphafold.

• 2021-07-16 Release Initial release · google-deepmind/alphafold
• 2021-07-16 DeepMind releases AlphaFold 2—an open source version of its protein-folding AI system | AI Business

AlphaFold 3 (Closed Source)

AlphaFold 3 is closed source and is not being sold either.

• 2024-05-08 Google DeepMind and Isomorphic Labs introduce AlphaFold 3 AI model

I speculate that AlphaFold 3 was made closed because Isomorphic Labs, a subsidiary of Alphabet, seems likely to achieve commercial success.
