Advancing coding in low‑resource programming languages

Summary

OpenAI reports improved ChatGPT performance on low-resource programming languages such as COBOL, Fortran, and Visual Basic, which have less training data than Python and JavaScript. Two new evaluations, MultiLangBench (building a SQLite-compatible engine across 20 languages) and a COBOL migration test, show GPT-6 Astra averaging an 87.4% test pass rate, up from 26.8% for GPT-5.6 Sol, and GPT-6.1 Sol reaching 86.6% COBOL migration accuracy at low reasoning effort.
