Many new projects still use https://github.com/TransformerLensOrg/TransformerLens as a core dependency. Over 500 public code repositories on Github rely upon the transformer-lens package, including ones created by leading organizations such as Meta Research, Redwood Research, Model Evaluation & Threat Research, Apollo Research, and Decode Research.
Bryce has a proven track record of consistent contributions to the library and is the best possible owner for ensuring the stability and growth of TransformerLens moving forward (as well as compatibility across other packages for doing mechinterp). He brings a deep expert understanding of the existing feature set and has demonstrated rapid iteration speed and skill to adapt the framework for recently launched models.
He also actively volunteers to answer community questions on Slack and integrates user feedback into the development roadmap with detailed progress updates to relevant stakeholders. I would also be excited to see Fabian's contributions going into TransformerLens 3.0 and beyond. I'd endorse and highly recommend donating to this manifund project to help it reach its full funding goal through the rest of 2025.
