Our dream with SimplexLab is to create an open-source community dedicated to better understanding collective intelligence and developing it for the benefit of its community and the rest of humanity.

We believe that intelligence is an emergent property: new capabilities arise when systems are combined in the right way. In principle, this means it should scale with the number of participants in a community. Unfortunately, this is rarely what we observe in large human organizations.

Our main goal is therefore to design and improve tools that allow people to combine their knowledge and reasoning more effectively, and to build a community around these tools.


Projects:

  • TorchJD: TorchJD is a library extending autograd to enable Jacobian descent with PyTorch. The full documentation is available at torchjd.org, with several usage examples.
