Claude Opus 4.5 isn’t just an upgrade; it’s setting new AI benchmarks, outperforming humans on engineering tests, and transforming enterprise workflows.
Anthropic’s Opus 4.5 achieved an unprecedented feat, scoring higher than any human candidate on their rigorous two-hour engineering exam. This benchmark, measuring technical ability and judgment under pressure, signals a major leap in AI problem-solving. Opus 4.5 also leads on SWEBench multilingual and verified scores, demonstrating superior ability in handling ambiguous bugs across multi-system issues.
Beyond benchmarks, Opus 4.5 shows remarkable creative problem-solving, exemplified by its unique resolution of a complex airline service scenario in the TA2Bench test. Anthropic prioritized safety, making Opus 4.5 highly robust against adversarial prompts and prompt injection through upgraded evaluation tools. It is Anthropic’s most aligned Frontier model, crucial for sensitive enterprise applications.
Efficiency is boosted with a new effort parameter, optimizing reasoning depth. Medium effort matches Sonnet 4.5’s best SWE verified score using 76% fewer output tokens, leading to substantial cost savings. The context system now self-compacts older conversation parts, maintaining stability for extensive, hours-long agent sessions and deep research tests.
For enterprise, Opus 4.5 interacts with computers and browsers, automating tasks in Excel and Chrome. Rakuten’s team reported peak agent capability in four iterations, much faster than other models. Claude Code features a methodical Plan mode and supports multiple simultaneous sessions, enhancing developer productivity. Pricing for Opus capabilities was also reduced, broadening access to advanced AI.
