Claude Opus 5
A good performance / EU-hosting balance for a European company.
Overview
Claude Opus 5 is Anthropic's top-tier proprietary model, built around autonomous agent workflows, reasoning and coding, with a one-million-token context window. No technical report or benchmark figures have been published yet, so real-world performance still needs to be validated per use case. Weights are closed and served only via Anthropic's own infrastructure in the US, meaning no on-premise deployment and data processed under US jurisdiction—a point European CIOs and CISOs should weigh carefully.
