OpenAI 发布面向 COBOL 等老语言的编程模型 GPT-6 Astra
OpenAI Launches a Coding Model for Older Programming Languages - Thurrott.com
OpenAI 发布编程模型 GPT-6 Astra，面向 COBOL、Fortran、Visual Basic 等老旧编程语言。OpenAI 为此构建了 MultiLangBench 和 COBOL migration 两项评测，GPT-6 Astra 在 MultiLangBench 的 20 种语言上得分 87.4%，GPT-5.6 Sol 为 26.8%；COBOL migration 得分 86.8%，高推理强度下为 97.9%，GPT-5.6 Sol 仅 5.4%。该模型已通过 OpenAI API 向开发者开放，用于 COBOL、Fortran、OCam 和 Visual Basic 的编程任务。

OpenAI today announced GPT‑6 Astra, an AI coding model tailored for COBOL, Fotran, Visual Basic, and other older programming languages.
“These languages have less code and documentation available for models to learn from than languages like Python and JavaScript, yet support critical infrastructure and essential services around the world,” the OpenAI announcement explains. “This work is guided by feedback from developers and enterprise customers who have told us that coding models often struggle with these languages.”
OpenAI developed two evaluations, MultiLangBench and COBOL migration, to ensure that its models can build new software in these older, less well-documented languages and preserve the behavior of older apps being modernized or otherwise migrated to newer languages. GPT-6 Astra scores 87.4 percent across 20 languages in MultiLangBench, up from 26.8 percent in GPT-5.6 Sol. And it scores 86.8 percent in COBOL migration–97.9 percent at high reasoning effort–up from just 5.4 percent for GPT-5.6 Sol.
“Our goal is to help models apply software engineering skills across more languages: Understanding unfamiliar repositories, planning changes, using build tools, running tests, and debugging failures,” OpenAI says.
GPT-6 Astra is available to developers through the OpenAI API on coding tasks for COBOL, Fortran, OCam, and Visual Basic.
