OpenAI has announced that its AI models are now significantly better at understanding and working with legacy programming languages like COBOL, Fortran, and Visual Basic. This development is crucial for banks, as 40% still rely on COBOL systems, and migrating these systems is costly and time-consuming. OpenAI's improved capabilities, tested through its MultiLangBench suite, show models like GPT-6 Astra achieving high pass rates in various languages, with GPT-6.1 Sol demonstrating strong accuracy in migrating COBOL programs to modern languages while preserving functionality.
