A library for building bots compositionally.

Project mention: Ask HN: What side projects landed you a job? | news.ycombinator.com | 2023-12-03

Not a job per se, but some friends and I wrote a library for building compositional chatbots (like for IRC not LLMs necessarily) encoded as Mealy Machines: https://github.com/cofree-coffee/cofree-bot/
That project then has since led to a long term collaboration with the Topos Institute where we are building type theory for Polynomial Functors: https://github.com/toposInstitute/polytt
Polynomial Functors are a really powerful abstraction from Category Theory which subsumes the co-algebraic approach to finite state machines used in `cofree-bot` and which can also be used to encode wiring diagrams, tactics engines, game semantics, neural networks, and dynamical systems in general.
