Run Claude Cowork on Claude Sonnet 4.6

Name: Claude Cowork
Author: Anthropic

by AnthropicPersonal agent

Claude Cowork is Anthropic's agent for knowledge work — the same agentic engine as Claude Code, but built for non-technical tasks inside the Claude desktop app, with no terminal required. Give it a goal and it works across your local files, folders, and applications, planning and carrying out the task while you steer, and it's aimed at research, analysis, operations, legal, and finance teams. On Opper it runs on any of 300+ models, not just Claude: point it at Opper's Anthropic-compatible gateway and keep inference in the EU or US on one key.
