OpenAI says new model improves COBOL migration
What happened
On 19 October 2026, OpenAI said its latest model makes clear progress in migrating legacy languages such as COBOL to C++, Java, Kotlin, Python and Rust. According to a 26 October report by The Verge, OpenAI's figures show GPT-6.1 Sol at 87% behavioural accuracy at low reasoning effort, rising to 98% at higher reasoning effort. Progress so far rests on the capability metrics OpenAI published; the report does not mention deployment in real migration projects or third-party verification results.
