According to God of Prompt on Twitter, Claude Opus 4.5 achieved an unprecedented 80.9% score on the SWE-bench verified benchmark, becoming the first AI model to surpass 80%. Unlike synthetic coding tests, SWE-bench evaluates models on real GitHub issues from active production repositories, reflecting the actual tasks developers face daily. This performance means Claude Opus 4.5 can autonomously resolve 4 out of 5 real-world software bugs, signaling a major leap in AI-driven software development and practical automation opportunities for engineering teams (source: @godofprompt, Jan 19, 2026).
