What's new in Sigma

AI

New model used for Snowflake AI provider

If you use a warehouse-hosted AI provider with a Snowflake connection, and your Snowflake account is hosted on AWS, Sigma now uses claude-sonnet-4-5 as the LLM.

For more details, see Configure a warehouse-hosted model as AI provider.

AI apps

Forms (GA)

Use the form element to create a clear interface for user data entry. Create a form manually, or based on an existing input table or stored procedure.

Forms can submit data to multiple data sources at the same time, and trigger action workflows at the time of submission, allowing you to centrally manage user input in AI apps.

For more information, see Use forms to streamline user data entry.

Functions and calculations

System functions in custom SQL queries

You can use system functions with the #formula directive in custom SQL queries to return information about the current workbook context, such as user name, email, and time.

For more information, see Write custom SQL.

Workbook elements

Configure background images for charts (Beta)

You can now add background images to cartesian (bar, line, scatter, area, waterfall, box and whisker, and combo) charts in order to build more complex visualizations, such as heat maps, or to further customize your chart's appearance.

To set a background image, upload a file or specify an image URL. If you use a URL, you can configure a dynamic URL by pressing = to open the formula bar and entering a formula that references a control value or column.

See Configure a custom background image for a chart for more information.

Dynamic column aliases in custom SQL queries

You can use a control value to create a dynamic column alias in a custom SQL query using the #identifier directive. This allows you to set column names in response to workbook contents.

For more information, see Reference workbook control values in SQL statements.

Bug fixes

Previously, image elements with the Shape set to Circle did not align properly with the element frame when choosing a Horizontal or Vertical alignment setting. Now, they follow the same behavior as other image elements.
Previously, when downloading a workbook page with a tabbed container as a PNG or PDF, only the first tab in the container was exported. Now, the export renders the current selected tab. This change does not apply to scheduled exports.
