What Are Snowflake Cortex AI Features in 2026?

Introduction

Snowflake is becoming more useful for businesses that want to work with data in a smarter and simpler way. In 2026, Snowflake Cortex brings together several tools that help teams understand documents, search information, analyse business data, and build intelligent applications without moving data between many different systems. For people starting their data career, Snowflake Online Training can also be a useful way to understand how these features work in real business situations.

Cortex is not just one tool. It is a collection of features that work with data already stored in Snowflake. These features include Cortex AI Functions, Cortex Agents, Cortex Analyst, Cortex Search, document processing, and other development tools. Together, they help companies turn large amounts of raw data into useful information.

What Is Snowflake Cortex?

Snowflake Cortex is a group of AI and machine learning features available inside the Snowflake platform. Its main purpose is to help users work with both structured and unstructured data.

Structured data can include sales numbers, customer records, product information, and financial reports. Unstructured data can include PDFs, emails, support tickets, contracts, images, audio, and other documents.

Earlier, companies often needed separate tools to work with these different types of information. Cortex makes it possible to perform many of these tasks directly within Snowflake.

This is especially useful for companies that already keep large amounts of business information in their Snowflake environment.

1. Cortex AI Functions

One of the important Cortex features in 2026 is Cortex AI Functions. These functions allow users to perform AI-based tasks using SQL and Python.

For example, a company may have thousands of customer reviews. Instead of reading every review manually, users can use functions to classify reviews, understand sentiment, translate text, extract information, or create summaries.

Some important functions include:

• AI_COMPLETE – Generates text based on a prompt and selected model.
• AI_CLASSIFY – Places text or images into categories.
• AI_FILTER – Checks whether content matches a natural-language condition.
• AI_EXTRACT – Extracts useful information from text and documents.
• AI_SENTIMENT – Understands the overall feeling in text.
• AI_TRANSLATE – Translates text between supported languages.
• AI_EMBED – Creates embeddings that can be used for similarity and search.
• AI_TRANSCRIBE – Converts supported audio and video into text.

Snowflake has also expanded its AI Functions to support text, images, audio, and video workloads. Several functions became generally available in 2025, while additional controls and capabilities have continued to arrive in 2026.

2. Cortex Agents

Cortex Agents is another major feature in 2026. An agent can understand a user's request, decide what steps are needed, use available tools, and return an answer.

For example, imagine a manager asks:

"Which products had falling sales last quarter, and what did customers say about them?"

This question needs more than one type of information. Sales numbers may be stored in tables, while customer comments may be stored in documents.

A Cortex Agent can use Cortex Analyst to work with structured data and Cortex Search to find information in unstructured data. It can then combine the results and provide an answer.

Agents can also use tools for code execution, charts, custom business logic, MCP connectors, and web search when enabled.

This makes Cortex Agents useful for applications where users need answers from different sources instead of simple database searches.

3. Cortex Analyst

Cortex Analyst focuses mainly on structured business data.

A business user does not always know SQL. They may simply want to ask:

"How much revenue did we make in July?"

Cortex Analyst can turn natural-language questions into SQL queries and use semantic information to understand business terms.

This can help managers, analysts, and other employees explore business information without writing every SQL query themselves.

In 2026, Snowflake also improved SQL generation within Cortex Agents. Agents using Cortex Analyst semantic views can generate SQL directly, improving accuracy and reducing latency for analytical queries.

This is useful because employees can spend more time understanding results instead of spending all their time writing queries.

4. Cortex Search

Businesses often have important information hidden inside documents. Examples include company policies, product manuals, contracts, customer conversations, and support documents.

Cortex Search helps users find relevant information from this type of unstructured content.

In 2026, Cortex Search received several important improvements. These include multi-index search, custom vector embeddings, dynamic filters, dynamic columns, and dynamic result counts. These improvements give applications more control over how information is searched and retrieved.

For example, a company could search customer support documents and ask for information only from a particular product, region, or time period.

This can make enterprise search faster and more useful.

5. Document Intelligence

Another useful area is document processing.

Many companies still receive information through PDFs, scanned documents, invoices, contracts, and reports. Manually entering information from these documents can take a lot of time.

Cortex provides document functions that can parse documents, extract information, classify documents, and prepare content for further analysis.

For example, a company could process invoices and extract:

• Invoice number
• Customer name
• Invoice date
• Total amount
• Product details

The extracted information can then be used for reporting or business workflows.

Snowflake's current document functions include capabilities such as AI_PARSE_DOCUMENT, AI_EXTRACT, AI_CLASSIFY, and AI_COMPLETE.

6. Multimodal Data Support

Modern businesses do not work only with text.

They may have product images, recorded meetings, training videos, audio calls, scanned documents, and other types of content.

Cortex AI Functions can work across several types of data depending on the function and supported model. This gives businesses more options for building applications that understand different forms of information.

For example, a customer service company could analyse recorded calls, convert speech into text, identify customer sentiment, and combine those results with customer records.

This can help teams understand customer problems more clearly.

Why Are Cortex Features Important in 2026?

The biggest advantage is that businesses can work with their data in one environment.

For learners, Snowflake Online Course content can help build an understanding of these features along with SQL, data warehousing, data engineering, and cloud concepts.

How Can Beginners Learn Cortex?

A beginner does not need to learn everything at once. Practical exercises are especially useful. Try working with customer reviews, sales data, or sample documents. Small projects can make the concepts much easier to understand.

For learners planning a career in cloud data platforms, Snowflake Training can provide a structured path for learning the platform and practicing real-world concepts.
