OpenSimula — open implementation of Simula-style mechanism design for synthetic data (in AfterImage) [P]

Hi r/MachineLearning, We added OpenSimula to our open-source dataset tool AfterImage: an experimental Python implementation of the Simula mechanism-design recipe from Davidson (TMLR, PDF; framing also in this research blog ). Problem it targets: For some SFT/eval setups you care less about “one prompt → one answer” and about controlled diversity over a reasoning space: which axes of variation exist, how you joint-sample them, and how you stress-test generations before they land in a JSONL file.
