How we build

Much of the Rust stack is developed with AI coding agents under human review. Two things we share openly:

Workflow. Agentic AI coding in Rust (slides) describes the rules, review and testing behind tenferro-rs and tensor4all-rs.
Provenance. After a developer meeting on copyright and scientific credit in July 2026, we adopted provenance rules for agents and per repository citation policies: tensor4all-rs, tenferro-rs, strided-rs.

Workshops and people

We also organize in-person workshops. See About for the people involved.
