The company shared results from two internal benchmarks. In MultiLangBench, which tests building a SQLite engine from scratch, the average pass rate across 20 languages was 87.4% using the GPT‑6 Astra model with maximum inference settings. For COBOL migration, the GPT‑6.1 Sol model reached 86.6% accuracy with low‑inference settings and 97.9% with higher inference, measured by byte‑for‑byte output matching the original.\n\nOpenAI emphasized that these scores do not guarantee flawless migration of whole business systems. It warned that expert review and testing against specific business rules are still required, as subtle differences in calculations can change outcomes. The announcement is framed as an evaluation of existing models rather than the launch of a COBOL‑specific AI product.","keyPoints":["OpenAI reported an 87.4% pass rate on MultiLangBench for 20 languages using GPT‑6 Astra max inference.","GPT‑6.1 Sol achieved 86.6% accuracy on low‑inference COBOL migration and 97.9% on high‑inference.","OpenAI cautions that migration still needs expert review and may not preserve all business rules."],"whyItMatters":"Modernizing legacy COBOL systems could lower maintenance costs, but the need for expert validation means AI assistance is not a turnkey solution.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":["OpenAI","IBM"],"models":["GPT-6 Astra","GPT-6.1 Sol"],"people":[]},"firstPublishedAt":"2026-10-20T04:21:00Z","updatedAt":"2026-10-20T04:21:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"[Breaking News] OpenAI's COBOL support evolves.
