Claude Opus 4.6
A good performance / EU-hosting balance for a European company.
Overview
Claude Opus 4.6 is Anthropic's latest proprietary model, built for complex reasoning and code generation, with a one-million-token context window. No model card or benchmark figures shipped alongside the launch, so its actual capabilities can't yet be checked against reproducible numbers. It remains fully closed: no open weights, no on-premise deployment, and all data runs through Anthropic's US infrastructure. API pricing lands at $5/$25 per million input/output tokens.
