About Claude Opus 5
Key Features
<strong>Agentic Coding.</strong> Claude Opus 5 handles complex multi-file features, large refactors, and end-to-end development work. It completes full tasks without leaving stubs or placeholders, making it ideal for ambitious software projects.
<strong>Cost-Effective Performance.</strong> The model delivers near-Fable 5 intelligence at half the cost, priced at $5 per million input tokens and $25 per million output tokens. It provides the same pricing as Opus 4.8 but with better performance.
<strong>Adjustable Effort Setting.</strong> Users can toggle between low, medium, and high effort levels to control how much the model thinks and how many tokens it uses. This helps teams manage AI expenses while maintaining quality output.
<strong>Knowledge Work Excellence.</strong> Claude Opus 5 scores as state-of-the-art on coding and knowledge work benchmarks like Frontier-Bench and GDPval-AA. It's built for daily office tasks including research, analysis, and professional writing.
<strong>Code Review and Debugging.</strong> The model reviews code with high precision, finding real bugs at a high rate while minimizing false positives. It's particularly strong at root-cause analysis and spotting configuration errors.
<strong>Long-Running Agentic Tasks.</strong> Claude Opus 5 maintains context across complex, multi-step workflows and can run autonomously with tools like browsers and terminals. It verifies its own work and iterates until tasks are complete.
Frequently Asked Questions
Claude Opus 5 is Anthropic's latest large language model designed for coding, enterprise workflows, and agentic tasks. It approaches the intelligence of Claude Fable 5 at half the cost, making it suitable for daily business use. The model is now the default on Claude Max and the strongest model available on Claude Pro.
Claude Opus 5 costs $5 per million input tokens and $25 per million output tokens, the same pricing as its predecessor Opus 4.8. This makes it half the price of Claude Fable 5 while delivering comparable performance on most tasks. A fast mode is also available at 2.5x the default speed for twice the base price.
Claude Opus 5 excels at agentic coding, knowledge work, enterprise automation, code review, and scientific research. It's particularly strong at multi-file features, debugging, root-cause analysis, and long-running tasks that require sustained reasoning. Companies use it for software development, legal work, financial modeling, and business automation.
Claude Opus 5 comes close to Fable 5's frontier intelligence at half the cost. It outperforms Fable 5 on some coding and knowledge work benchmarks but remains behind on specialized cybersecurity tasks. The model is designed for everyday use rather than the most demanding edge cases.
