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

OpenSimula is an experimental Python implementation of Simula mechanism design, added to the AfterImage open-source dataset tool. It addresses the need for controlled diversity in LLM SFT/eval setups by generating varied synthetic data through LLM-built taxonomies, weighted sampling, and critic loops.
