Astrophysicist Franco Vazza says an AI tool helped him uncover numerical artefacts in a new cosmological simulation that he had previously overlooked. He describes the analysis as unattractive but very useful, saying he worked with an LLM trained on a large custom set of instructions. The post is drawing attention for showing AI being used as a genuine debugging aid in scientific research rather than as a novelty.

Why now: Researchers and observers are interested in a concrete case of an LLM catching real technical flaws in scientific code.
