Why it matters
COBOL migration tests whether coding models can preserve business behavior across costly modernization projects. OpenAI's results show progress on its own evaluations, while production safety and enterprise adoption remain unresolved.
OpenAI says its latest models have improved at writing and migrating code in COBOL, Fortran and Visual Basic, targeting languages that remain embedded in financial and other business systems.

Its technical account says developers can try the models on coding tasks through OpenAI's API.
