Open source
Our products stand on open-source work. These are the libraries, fonts and models we use, with their licences. Thank you to everyone who builds and maintains them.
Licences as published by each project, checked against the versions we run on 18 October 2026. Full licence texts are in each project’s repository; for a notice file, write to [email protected].
This website
The website’s own code is written by us. Both typefaces are open source and served from our own server; the photos are listed on the Media page.

Phonos
In the Research Preview, Phonos runs published models through NVIDIA BioNeMo NIM, for testing; paid plans run them on machines operated by FyreFly Systems. MolMIM and GenMol are NVIDIA models, not open source: GenMol is under the NVIDIA Open Model License, and MolMIM is licensed for research and development only, so it is offered in the Research Preview for testing only and is not part of paid plans.
