Claude Sonnet 4.6 Now Available in Microsoft Foundry

Great news for developers and teams pushing the boundaries of AI! Microsoft Azure has announced the integration of Anthropic's powerful Claude Sonnet 4.6 into Microsoft Foundry, making it available for immediate use starting February 17th. This marks a significant step forward in providing frontier AI performance for a wide range of demanding tasks.

What it does

Claude Sonnet 4.6, now available in Microsoft Foundry, is designed to deliver exceptional performance across coding, agentic workflows, and professional work at scale. It offers teams the ability to handle complex tasks with greater efficiency and accuracy. This expands on the already impressive capabilities within Foundry, which also saw the availability of Claude Opus 4.6 earlier on February 5th, further enabling developers to delegate complex tasks end-to-end and trust AI to execute independently in production.

Why it matters

The integration of Claude Sonnet 4.6 into Microsoft Foundry is more than just adding another model; it's about empowering innovation. This move aligns with Azure's broader vision, including the introduction of "Agentic cloud operations" on February 11th, a new method designed to manage the increasing scale and complexity of modern applications and AI workloads.

Azure's commitment to providing robust and accessible AI solutions is clear. The Microsoft Sovereign Cloud expansion on February 24th notably included Microsoft Foundry with large model and modern infrastructure support, showcasing Azure's strategic investment in secure, advanced AI capabilities. Moreover, Azure is making AI development more accessible and affordable for everyone. Take for example the new "Budget Bytes" series, introduced on February 19th, which helps developers build production-quality AI applications on Azure for under $25! For those focused on optimizing costs at the hardware level, Azure continues to innovate with solutions like Maia 200, an AI inference accelerator engineered on January 26th to dramatically improve the economics of AI token generation. These initiatives collectively underscore Azure's dedication to providing comprehensive Azure AI Solutions for every developer and enterprise.

How to try it

Teams looking to leverage the power of Claude Sonnet 4.6 can access it today through Microsoft Foundry. Azure provides a rich ecosystem to support your AI journey from data to deployment. For instance, Azure Databases are continuously being supercharged for AI; PostgreSQL on Azure, updated on February 2nd, now integrates GitHub Copilot AI assistance and built-in model management to unlock its full potential.

For robust data handling crucial to any AI workload, Azure also continuously enhances its Azure Storage capabilities. This includes instant access for incremental snapshots of Premium SSD v2 and Ultra Disk, introduced on March 2nd, providing instant creation, disk restore, and production-ready performance. Additionally, the Azure NetApp Files Elastic zone-redundant service, made available on February 4th, offers enhanced storage resiliency with continuous data availability and zero data loss for mission-critical applications.
