Are NNUE Nets Specific to Chess Engines or They Universal to All Engines? Can the NNUE's Nets be Swapped to other chess engines so the pattern recognition is available to all engines or does Stockfish heuristics or Dragon's chess engine work better with its own specific programming algorithms?

The NNUE networks are neither standardized nor self-contained. If a given network made for engine A works with an engine B, A!=B, then it's by accident, unless otherwise specified by the engine B's author.

That being said, many engines use the “original” architecture and format employed up through SF13. These nets can then be loaded and used in many different but not all engines.

Who is saying I'm a forum Troll? I Rarely post but I was wondering if the NNUE part is interchangeable with other engines. Why am I being insulted for asking a question dangi12012?

Assuming this is not humour, you are mistaking @sopel's signature as a message to yourself.

Dietrich, I thought you are the one who could know this. Is there an old format net trained on Lc0 games/evaluation? I know that SF devs trained nets based on Lc0, but I found only new nets.

I did take this as a backdoor insult to me, thank you for telling me as that comment ruined my day.

You are best off asking in the SF discord. Night Nurse and Dark Horse are both trained on mcts/nn data but from Bad Gyal instead of lc0.
