We are thrilled to announce the availability of Claude Sonnet 4.6, Anthropic’s latest model, on Snowflake Cortex AI. As a launch partner with Anthropic, we’re providing same-day availability of Claude Sonnet 4.6 in private preview in the U.S, with support for other regions, including Europe coming soon. It is available within the Snowflake perimeter for use with Cortex Code, Cortex AI Functions and Cortex REST API and will be coming soon in Snowflake Intelligence.  

Claude Sonnet 4.6 

Sonnet 4.6 is Anthropic’s latest premium frontier model, approaching Claude Opus 4.6-level intelligence at a fraction of the price. Sonnet 4.6 drives tasks forward while autonomously planning, executing and course correcting with minimal input. It’s highly steerable, giving you fine-grained control over decision-making and autonomy. When deep thinking isn’t needed, it’s capable of delivering near-instant responses.

What you can do with Claude Sonnet 4.6 on Snowflake

Sonnet 4.6 joins other leading frontier models in Snowflake Cortex AI, enabling a wide range of enterprise use cases, all within Snowflake’s security and governance perimeter. With Claude Sonnet 4.6, you can:

• Speed up development with Cortex Code: Snowflake’s AI coding agent actually understands your enterprise data, governance and workflows, enabling teams to go from idea to production quickly without breaking trust or impacting scale. Now powered by Claude Sonnet 4.6, Cortex Code delivers faster performance, higher-quality reasoning and more cost-efficient code generation and agentic execution. It brings secure, Snowflake-aware assistance directly into Snowsight, the CLI and the local dev tools.  For developers, data engineers, analysts and builders, it turns natural language into production-ready pipelines, analytics and AI agents — collapsing weeks of glue work into minutes, while staying governed, interoperable and enterprise-grade. You can try Claude Sonnet 4.6 in preview using /model command within the CLI: 

• Build advanced enterprise intelligence agents: Snowflake Intelligence introduced a new category of agents designed to transform how organizations work, collaborate and innovate by fostering a truly data-driven culture. Every employee, regardless of technical depth, can ask complex questions in natural language, uncover the “why” behind every “what” and take confident action. For developers, admins and builders, Sonnet 4.6 will extend this foundation, enabling the creation of advanced agents that reason across complex data, write and execute code autonomously and orchestrate analytical and operational workflows.

• Analyze structured and unstructured data with unparalleled precision: Cortex AI Functions make it easy to build scalable AI pipelines across multimodal enterprise data using SQL. These functions deliver high-performance processing at a lower cost than manually orchestrated AI pipelines, enabling trusted insights across the enterprise while maintaining the security and governance capabilities Snowflake is known for. For example, with the AI_COMPLETE function, analysts can apply natural language instructions directly in SQL, leveraging the latest  models such as Sonnet 4.6. This gives them the ability to analyze their data faster and serve their customers.

• Build AI applications closer to secure data: Use the Cortex REST API to build agentic enterprise applications within the Snowflake security perimeter. Developers can leverage new capabilities such as Sonnet 4.6’s adaptive thinking to enable the model to decide how much to think on a task. They can get started quickly using the Anthropic SDK by pointing it to their Snowflake Cortex REST API endpoint, enabling a seamless integration with familiar Anthropic tooling.

Moving agentic AI from concept production is now a strategic imperative. Powered by Anthropic’s Claude Sonnet 4.6, agents can autonomously plan, execute and course correct tasks with minimal human input, driving real work forward at scale. With multiple entry points, from Cortex Code CLI to Snowflake Intelligence, Cortex AI Functions and REST APIs, customers can easily adopt this capability and accelerate their path to high-impact, production-ready agentic AI at scale.
