OpenAI says GPT-6.1 Sol is dramatically better at migrating legacy code

Summary

OpenAI says its newer models, including GPT-6.1 Sol, are much better at writing and migrating code in legacy languages such as COBOL, Fortran and Visual Basic. On its MultiLangBench, GPT-6 Astra averaged an 87.4% pass rate, up from 26.8% for GPT-5.6 Sol, and GPT-6.1 Sol reached 86.6% accuracy on COBOL-to-modern-language migration at low reasoning effort. The source adds that production migrations would still need expert review and testing.
