# Claude Opus 4.8 Tops Meta's SWE-Together Coding Benchmark

> Anthropic's Claude Opus 4.8 just set a new benchmark for coding tasks, achieving 63% pass@1 on Meta's SWE-Together suite, 109 multi-turn engineering problems that require both reasoning and tool use to solve. This matters because coding benchmarks are less abstract than general reasoning tests; they reflect tasks that teams actually need solved, making them a stronger signal of real-world utility. The benchmark specifically measures multi-turn interactions where the model must handle feedback, debugging, and iterative refinement, closer to how engineers actually work than single-shot code generation. Opus 4.8 outperformed other frontier models, suggesting Anthropic's focus on reasoning and long-context understanding is paying off for complex technical tasks. For engineering teams evaluating which AI to deploy, this result tilts the scales toward Claude for development work. It's also a reminder that benchmark dominance in one area (coding) doesn't automatically transfer elsewhere, but for the core task of helping developers write code faster, Anthropic has a credible edge.
