These features can help you do more with your data in less time than ever before. - **Snowflake Cortex** is a suite of AI features that use large language models (LLMs) to understand unstructured data, answer freeform questions, and provide intelligent assistance. This suite of Snowflake AI Features comprises: - [Cortex Agents](/user-guide/snowflake-cortex/cortex-agents) - [Snowflake Cortex AI Functions (including LLM functions)](/user-guide/snowflake-cortex/aisql) - [Cortex Analyst](/user-guide/snowflake-cortex/cortex-analyst) - [Cortex Fine-tuning](/user-guide/snowflake-cortex/cortex-finetuning) - [Cortex Search](/user-guide/snowflake-cortex/cortex-search/cortex-search-overview) - [%sf-intelligence%](/user-guide/snowflake-cortex/snowflake-cowork) - [Cortex Code](/user-guide/cortex-code/cortex-code) - [Cortex Code in Snowsight](/user-guide/cortex-code/cortex-code-snowsight) - [Cortex Code CLI](/user-guide/cortex-code/cortex-code-cli) - [Cortex Code Agent SDK](/user-guide/cortex-code-agent-sdk/cortex-code-agent-sdk) - [Cortex Code CLI Model Context Protocol (MCP) support](/user-guide/cortex-code/cortex-code-mcp) - [Cortex Code CLI Agent Client Protocol (ACP) support](/user-guide/cortex-code/cortex-code-acp) - [Cortex Code CLI plugins](/user-guide/cortex-code/cortex-code-plugins) - [Cortex AI Guardrails](/user-guide/snowflake-cortex/cortex-ai-guardrails) - **Snowflake ML** provides functionality for you to build your own models. - [ML Functions](/guides-overview-ml-functions) simplify the process of creating and using traditional machine learning models to detect patterns in your structured data. These powerful out-of-the-box analysis tools help time-strapped analysts, data engineers, and data scientists understand, predict, and classify data, without any programming. - For data scientists and developers, [Snowflake ML](/developer-guide/snowflake-ml/overview) lets you develop and operationalize custom models to solve your unique data challenges, while keeping your data inside Snowflake. Snowflake ML incorporates model development classes based on popular ML frameworks, along with ML Ops capabilities such as a feature store, a model registry, framework connectors, and immutable data snapshots. ## Use of Snowflake AI features Snowflake AI Features and their underlying models are designed with the following principles in mind: - **Full security.** Except as you elect, all AI models run inside of Snowflake's security and governance perimeter. Your data is not available to other customers or model developers. - **Data privacy.** Snowflake never uses your Customer Data to train models made available to our customer base. - **Control.** You have control over your team's use of Snowflake AI Features through familiar [role-based access control](/user-guide/security-access-control-overview). ## AI/ML model update process Snowflake is continually working to improve the quality of its offerings, including the models powering the Snowflake AI Features. This section describes how updates to those models fit into [Snowflake's Behavior Change](/release-notes/intro-bcr-releases) process. ## Model Update and Behavior Change Policy ### Overview Snowflake continuously updates the models that power Cortex AI features to improve quality, performance, and availability. These updates may introduce changes to model behavior, availability, or lifecycle status. This document describes how model changes are defined, how they are communicated, and how model lifecycle and deprecation are managed. ### Model lifecycle Models in Cortex follow a defined lifecycle to communicate readiness and stability: - Private Preview - Public Preview - General Availability (GA) - Legacy - End of Life (EOL) Lifecycle status reflects the maturity and support level of a model. As models progress through these stages, their status will be reflected across customer-facing surfaces. Preview models are intended for evaluation and may change more frequently. GA models are considered stable and suitable for production use. ### Types of model changes A model update is considered a behavior change if it results in any of the following: - Changes to required syntax, including specifying a model or model version - Changes to the structure of model outputs - Deprecation of a model These changes may impact how customers interact with models and should be reviewed as part of normal governance processes. ### How changes are communicated Snowflake communicates model-related updates through the following mechanisms: - [Behavior Change Releases (BCRs)](/release-notes/intro-bcr-releases) — Used for changes that may require customer action or impact existing workflows - [What's New](/release-notes/new-features) — Used for improvements or additions that do not materially change how customers interact with models Model deprecations are communicated separately from bundled releases to provide clear and timely notification. ### Deprecation policy Snowflake periodically deprecates models to ensure customers have access to high-quality, well-supported options. For General Availability (GA) models: - Snowflake will make reasonable efforts to provide at least 60 days advance notice prior to deprecation For Preview models: - Deprecation timelines are not guaranteed and may occur with shorter notice During the deprecation period: - Customers are expected to migrate to alternative models before the deprecation date - After deprecation, models may no longer be available for use Lifecycle status will reflect deprecation through the transition to Legacy and ultimately End of Life. ### Legal notices - If you choose to use any of the Snowflake AI Features, your use is subject to our [Acceptable Use Policy](https://www.snowflake.com/legal/acceptable-use-policy/). - The outputs of Snowflake AI Features may be inaccurate, inappropriate, inefficient, or biased. Decisions based on such outputs, including those built into automatic pipelines, should have human oversight and review processes to ensure they are safe, accurate, and suitable for your intended use. - Your use of any Snowflake AI Feature that is identified as being powered by a third-party, open-source model is subject to any applicable license agreement and/or acceptable use policy set forth under the Offering-Specific Terms page available at [https://www.snowflake.com/legal/](https://www.snowflake.com/legal/). - For further information, see the [Snowflake AI Trust and Safety FAQ](https://www.snowflake.com/en/legal/snowflake-ai-trust-and-safety/).
