Anthropic has launched Claude Opus 5, a new AI model that promises to deliver nearly the same performance as its top-tier model, Claude Fable 5, but at about half the cost. This release, made public on July 24, positions Opus 5 as a reliable tool for coding tasks, AI agents (software that can perform actions on your behalf), and business workflows. What Is Claude Opus 5? Opus 5 upgrades Anthropic’s earlier Opus 4.8 model, arriving just two months after the last update. When companies create products using AI through an API (a connection that allows software to communicate), those token costs can add up quickly at scale.
