OpenAI Enhances Model Capabilities for Low-Resource Languages Like COBOL and Fortran
OpenAI has announced model improvements targeting low-resource and legacy programming languages, aiming to assist organizations in deciphering and modernizing mission-critical legacy codebases.
OpenAI has introduced technical enhancements designed to improve how its models handle low-resource and legacy programming languages, with a particular focus on COBOL, Fortran, and Visual Basic. Unlike mainstream languages such as Python and JavaScript, these technologies have limited modern documentation and public training data, yet they still run critical workloads across global banking, ATM networks, and scientific modeling.
According to the company, the improved capabilities focus on comprehending decades of accumulated business logic. By assisting developers in translating, refactoring, and documenting legacy code without altering established behaviors, OpenAI aims to address persistent talent shortages and technical debt in long-standing enterprise environments.
While software engineering teams view the updates as a positive step toward accelerating legacy migrations, industry observers note that the primary difficulty remains verifying behavioral equivalence across complex, poorly documented edge cases in mission-critical operations.

Cobolen.wikipedia.org · supportingCOBOL (Common Business-Oriented Language; /ˈkoʊbɒl, -bɔːl/) is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. Many large financial institutions were developing new systems in the language as late as 2006, but most programming in COBOL today is purely to maintain existing applications. Programs are being moved to new platforms, rewritten in modern languages, or replaced with other software. [...] ### Modernization efforts [edit] In 2006 and 2012, Computerworld surveys (of 352 readers) found that over 60% of organizations used COBOL (more than C++ and Visual Basic .NET) and that for half of those, COBOL was used for the majority of their inter
Brush up your COBOL: Why is a 60 year old language suddenly in demand? - Stack Overflowstackoverflow.blog · supportingOnce upon a time, when the world and computers were new, I was in an Associate's Degree program for Data Processing—there were no "computer science" programs then—in which I had to study accounting, math, statistics, and three computer languages: IBM/360 Basic Assembly Language, FORTRAN, and COBOL. By the 80's, students were being told that COBOL was a dead language, and no one was studying it any more. Now, in 2020, governments and banks are pleading for COBOL programmers, the language that wouldn't die. Governor Laura Kelly of Kansas said:
What Is COBOL? | IBMibm.com · supportingAlthough COBOL is considered a legacy system, many government and private sector organizations continue to use it to run financial, administrative and business applications. In fact, COBOL’s imperative, procedural and (in its newer iterations) object-oriented configuration serves as the foundation for more than 40% of all online banking systems.1 It also supports 80% of in-person credit card transactions, handles 95% of all ATM transactions, and powers systems that generate more than USD 3 billion of commerce each day.1 Due to its superior stability and processing power, it continues to play an integral role in helping businesses maintain apps and programs in existing architectures. [...] Stability COBOL is known for its stable, reliable performance in mission-critical applications. Systems written in COBOL tend to have high uptime and experience few failures, which is vital to the nonstop operations of financial institutions and government services. Scalability Developers can
