TMTPOST -- TikTok's parent company ByteDance has officially open-sourced Doubao's first multilingual SWE dataset, named Multi-SWE-bench, which can be used to assess and enhance the "automatic bug-fixing" capabilities of large models. Building on the SWE-bench, Multi-SWE-bench is the first benchmark to cover seven mainstream programming languages beyond Python, making it a comprehensive evaluation standard for "full-stack engineering." The data is sourced from GitHub issues and has been constructed over nearly a year to evaluate and improve the advanced programming intelligence of large models.
