Claude Sonnet 4.6 in Microsoft Foundry delivers near-Opus intelligence with a 1M-token context window, adaptive thinking and effort controls, stronger code reasoning, browser-based computer use for legacy systems, and scalable, governed deployment for enterprise automation and knowledge work.

Claude Sonnet 4.6 is now available in Microsoft Foundry. It brings near-Opus intelligence optimized for coding, agents, and professional workflows.

Main feature and impact

Claude Sonnet 4.6 introduces a one million token context window in beta. This supports long, multi-document reasoning across large codebases and datasets. Adaptive thinking and effort controls let teams tune quality, latency, and cost. The model offers 128K maximum output for extended generations. Enterprises gain fewer context resets and more consistent multi-turn behavior.

Practical implications

Developers can run iterative code workflows without losing architectural context. QA and browser automation workflows can span legacy interfaces without API changes. Finance and analytics workflows get improved spreadsheet handling and modeling precision. Conversational products scale with consistent multi-turn quality. In Microsoft Foundry, governance and operational tooling support enterprise deployment and compliance.

“Claude Sonnet 4.6 delivers frontier intelligence at scale, built for coding, agents, and enterprise workflows. With Sonnet 4.6, customers get access to powerful reasoning and productivity capabilities.”

Claude Sonnet 4.6 reduces editing cycles and context fragmentation for teams. Next steps: validate quota availability, test effort controls, and integrate Sonnet into agent pipelines.
