Claude Opus 4.5 leads coding benchmarks; DeepSeek V4 excels at large refactors

A comparison of Claude Opus 4.5 and DeepSeek V4 highlights their distinct strengths in coding tasks. Claude Opus 4.5 excels at precise, surgical fixes for production bugs and single-file issues, achieving a leading 80.9% score on the SWE-bench benchmark. DeepSeek V4, conversely, is better suited for large-scale, multi-file refactoring and repository-wide migrations when provided with extensive context. The choice between them depends on the scope and nature of the coding task. AI

影响 Claude Opus 4.5 and DeepSeek V4 offer complementary strengths for developers, guiding optimal model selection for different coding tasks.
