Anthropic’s new model Claude Opus 4.5 represents a major leap forward in coding, reasoning, and tool-based workflows, offering significantly improved accuracy and token efficiency that enables it to tackle more complex, long-running tasks than earlier versions. It’s been used to build more capable agents that maintain context across large workflows, dynamically select appropriate tools, and execute multi-step operations with fewer iterations and costs. Beyond software development, the model is advertised as excelling in spreadsheet automation, financial modelling, and enterprise-grade document generation—claiming performance gains of 20-30% in key metrics and up to one-third of the cost of its predecessor. With broad availability across major cloud platforms and integrations into production APIs, this release positions the model for large-scale deployment in sophisticated workflows and aims to raise the bar for what foundation models can deliver in real-world enterprise settings.
