Anthropic strikes back with Claude Opus 4.5

Anthropic released Claude Opus 4.5 just one week after Google's Gemini 3 Pro claimed top AI performance rankings, delivering significant improvements in specialized areas despite not achieving overall dominance. The new model made history by becoming the first to exceed 80% on the SWE-bench Verified test, scoring 80.9% in solving real-world software engineering problems. While Claude Opus 4.5 demonstrates strong performance across reasoning and task-automation evaluations, Anthropic appears focused on dominating specific niches rather than competing for general supremacy.
