Snowflake Adds Claude Fable 5 to Cortex AI

Snowflake is bringing Anthropic's latest large language model, Claude Fable 5, to its Cortex AI platform. Announced as a launch partner, Snowflake is offering Claude Fable 5 in private preview on the same day as its release, making it accessible within Snowflake's secure data perimeter. This integration aims to bolster enterprise AI capabilities for complex, multi-step workloads.

Claude Fable 5, described as Anthropic's most capable generally available 'Mythos-class' model, is engineered for enterprise deployment. It promises to tackle problems previously too complex, ambiguous, or time-consuming for AI models, facilitating end-to-end work that could take humans days or weeks.

Enhanced AI Workflows on Snowflake

The integration extends across several Snowflake services.

• Snowflake CoCo, the AI coding agent, now leverages Fable 5 for improved reasoning and code generation, accelerating the creation of data pipelines and AI agents from natural language prompts.
• Snowflake CoWork, a personal work agent for knowledge workers, gains enhanced reasoning and code generation capabilities. This allows for deeper analysis of structured and unstructured data, automation of tasks, and the execution of complex, multi-step business problems through features like Deep Research and integrations with tools like Gmail and Slack.
• Cortex AI Functions enable the building of scalable AI pipelines using SQL across multimodal enterprise data. Fable 5 specifically enhances precision in analyzing charts, tables, and scientific figures, improving document parsing and multimodal pipelines. The example provided shows using the AI_COMPLETE function directly in SQL to summarize financial filings.
• Cortex Inference allows developers to build agentic enterprise applications within Snowflake's security perimeter. Fable 5's adjustable effort levels balance reasoning and latency, and its self-validation capabilities enable more autonomous operations. Developers can utilize the Anthropic SDK by pointing to their Snowflake Cortex Inference endpoint for seamless integration.

Snowflake emphasizes that these advancements are delivered within its established security and governance framework, allowing businesses to deploy advanced agentic AI into production faster and more reliably.
