The MIT report linked in the article is giving a 404 for some reason. Here is the web archive version: https://web.archive.org/web/20250818145714if_/https://nanda....
Their cardinal code repo is also 404. The NANDA Lab also does coding, their publication at AAAI 2025 is titled: "CoDream: Exchanging dreams instead of models for federated aggregation with heterogeneous models" [1]. However, the link to the Github repo is broken. Fascinating paper, sad about the missing code.
