Claude Opus 4.5 (latest) (EU)

Claude Opus 4.5 is Anthropic's latest top-tier offering in the Claude family, introduced on November 24, 2025 and described in partner coverage as the company's most intelligent model to date. It is positioned as a premium frontier system aimed at tasks that require sustained reasoning and tool coordination, including coding, computer use, and complex office work. The Snowflake announcement frames it as setting a new standard across these workloads, outperforming earlier Claude variants such as Sonnet 4.5 and Opus 4.1 on that partner's evaluation surfaces.

In practical terms, Claude Opus 4.5 is designed for teams that need a single model to handle long-running agentic workflows alongside traditional natural language tasks. Anthropic targeted the release at scenarios where models must chain together multiple steps, call external tools, and produce reliable outputs across coding and productivity contexts. Its placement within the Claude Opus line signals an emphasis on depth of reasoning over lightweight deployment, making it a fit for organizations standardizing on a flagship model for advanced development and office automation use cases.
