A2rchi (AI Augmented Research Chat Intelligence) is an open source, end-to-end framework to quickly build an AI support agent for classes and research resources developed jointly by faculty and students in MIT’s physics and computer science departments. It has already been successfully deployed for SubMIT, the private cloud at MIT’s Physic Department, and for the 8.01 and 8.511 courses. A2rchi allows students to quickly find help on how to use the SubMIT infrastructure or helps TAs to answer questions on Piazza. These test deployments demonstrated that A2rchi can significantly reduce the load on TAs, Lecturers, and support staff. In contrast, to other GenAI chat support solutions, A2rchi is fully open-source, works with different foundational models, and most importantly is integrated with Piazza and Redmine, a widely used open-source flexible project management web application including a ticketing system.
