New on Sigma April-June 2026: Sigma Agents, Sigma Assistant, Code-backed BI & More

The past three months were the busiest shipping stretch we have had in a while, and the throughline is hard to miss: Sigma is becoming a platform where AI does analytical work inside your governance perimeter, whether that AI is Sigma Agents acting on live warehouse data, Sigma Assistant answering questions in context, or a coding tool writing workbooks on your behalf. Here is what landed between April and June, starting with the three releases that matter most.

Sigma Agents

Sigma Agents are AI agents that live inside Sigma and take action on your data via Sigma's robust action framework. Because agents run directly against your warehouse, the row-level security, column-level permissions, and audit trails your team already maintains carry over automatically; there is no separate AI platform to stand up and no copy of your data sitting somewhere new.

Agents now plug into your software development lifecycle, support governed metrics as context, and come with a rebuilt building experience that makes assembling an agent feel closer to configuring a workbook than writing a spec. Every customer also gets AI usage reporting out of the box, with token usage broken out by agent, so the people responsible for cost and governance can see what their agents are doing and what it costs.

If your team has been waiting for a sanctioned way to deploy AI agents to live warehouse data, the wait is over.

Sigma Agents are available to all customers.

Sigma Assistant: one interface for AI analysis and building

In April, Ask Sigma became Sigma Assistant, and in May, we unified the analysis and building experiences into one interface. Ask a question and Sigma Assistant answers it using the context your organization has already built: your data models, your certified metrics, and the endorsed workbooks that signal which sources your team actually trusts. Describe what you want, and Sigma Assistant builds it, whether that is a single chart or the scaffolding of a full application.

The shift is bigger than a rename. Assistant runs on a new architecture with better accuracy on real-world questions, and it is contextual in the literal sense: open it inside a workbook, and it understands the elements on the page and the data sources behind them. Because everything happens within the governed workspace where your data already lives, the AI analysis your teams run with Assistant has the same permissions as the analysis they do by hand.

Sigma Assistant for analysis is available for all customers. Sigma Assistant for building is available in beta. Reach out to your Sigma representative to get early access.

Code-backed Sigma: the fastest path to migrate from legacy BI

Over the spring, Sigma quietly became a platform where you can write in code. Data model APIs went GA in April, giving you programmatic read and write over data models, with every edit becoming a versioned artifact your team can diff, review, and redeploy. The Sigma MCP server also went GA, and in May, we released our first open-source product: agent skills that let coding agents like Claude Code authenticate to Sigma, call our APIs, and build data models from natural language. Workbooks as code, now in private beta, extends the same idea to the workbook itself, with pages, elements, layout, and configuration all expressible as code and manageable through the API.

For anyone staring down a BI migration, this changes the math. When a workbook is code, a coding agent can read a legacy dashboard, interpret its structure, and generate the Sigma equivalent programmatically, from discovery through verified data parity, in a single run, with a final check comparing every chart's numbers back to the source. What used to be a quarter of manual rebuild work now looks like a supervised afternoon. We have built an end-to-end guide for Tableau migration, and the same approach extends to other legacy BI platforms where the structure can be interpreted cleanly.

The workbooks-as-code API is in private beta, available to all customers upon request.

Roundup

That's not all we launched these last few months. Our full roundup includes:

• Sigma Tables: Writeback that lives in your warehouse rather than inside a single app, so any app, agent, or external system can read and write the same governed table. Multiplayer editing, schema changes, and the ability to make existing warehouse tables editable. It's the next evolution of writeback for building complex applications.
• Sigma Public: A free platform where anyone can build, share, and explore AI Apps, agentic analytics, and visualizations, with no license and no warehouse required. The easiest way yet to try Sigma or show your work to the world.
• API Actions (GA): Call external API endpoints straight from a workbook to update your CRM, send alerts, trigger workflows, or orchestrate multi-step processes, with reusable connectors and enterprise auth built in.
• Amazon Bedrock as an AI provider (public beta): Power Assistant, Agents, and the rest of Sigma's AI features through Bedrock, keeping model traffic inside your AWS relationship.
• ClickHouse connector (public beta): Now with writeback through materializations and warehouse views, broader function coverage, and a larger connection pool.
• Quality of life updates: CSV upload limits raised from 200 MB to 1 GB, multiple identity providers for SSO, workbook page sidebars for app-style navigation, and dynamic chart axis ranges driven by formulas or controls.
• Other awesome stuff: Forms, repeated containers, single row containers, value lists, and input table audit history all moved from beta to generally available, rounding out the toolkit for card-based layouts and auditable data entry.
