A system called AutoChemSchematic AI produces fully physics‑validated process and instrumentation diagrams (PFDs/PIDs) using small-domain language models tied into DWSIM simulations.

It utilizes hierarchical knowledge graphs for over 1,020 chemicals, transformer-based language models, simulator-in-loop validation, and inference-time pruning to ensure both correctness and efficiency—dramatically reducing R&D cycles from discovery to plant deployment.
