Anthropic launches Claude Opus 5, positioning the update primarily for developers and enterprise users. Across reports, the upgrade focuses on improved coding capabilities and stronger reasoning efficiency, along with changes intended to work better with prompting and tool use. ZDNet and Digital Trends both say the new model delivers performance that is close to Fable 5 in at least some tasks, according to Anthropic’s testing or comparisons. The outlets also report that Opus 5 is offered at the same API price as Opus 4.8, which is described as maintaining the cost level while providing the new performance and functionality. Both sources emphasize that Opus 5 includes updates related to tool calling and prompt caching, aiming to make repeated interactions more efficient for applications that rely on tool workflows. Overall, the coverage converges on the same key points: Opus 5 is a coding-focused Claude update, it maintains Opus 4.8 API pricing, and it reaches near-Fable performance in certain benchmarks.
