- OpenAI said its newest models show major performance leaps in low-resource legacy languages including COBOL, Fortran, and Visual Basic, code that still underpins systems at banks and government agencies.
- OpenAI stated the advances bring stronger capabilities for building and migrating software written in these legacy languages, framing it as practical tooling for institutions running decades-old code.
Why it matters: Banks and government agencies still run core operations on COBOL, Fortran, and Visual Basic, and most modern AI coding tools have historically been weak in these languages — OpenAI explicitly names migration and maintenance as the use case, making the institutions stuck on legacy stacks the stakeholder with the most to gain.
