Can you ask the built-in assistant a question in plain English?

Yes
Quoted from Sigma’s docsSigma Assistant is a natural language query (NLQ) interface that allows you to ask questions about your data and interact with AI-generated responses.
Source: help.sigmacomputing.com/docs/ask-natural-language-queries-with-assistant · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

Someone types a question the way they would say it out loud and the built-in assistant returns an answer or a working query against your data, without needing SQL or a dashboard someone built first. An assistant that only suggests or completes SQL the user is already writing is partly; one that writes the query from a plain-English description is yes, including inside a code editor.

Can you refine the answer by carrying on the conversation?

Yes
Quoted from Sigma’s docsYou can continue to ask follow-up questions to refine your analysis or understanding of the data source.

The assistant holds the thread, so you can say “now split that by region” and it knows what you are referring to.

Does the answer expose the query or analytical steps used to derive it?

Yes
Quoted from Sigma’s docsClick View SQL to review the exact query Assistant sent to your data platform.

Claude yes · GPT yes · Gemini yes
Grading standard

The answer exposes the query or analytical steps used to derive it. Named fields belong to field citation; upstream dependencies belong to lineage.

Does the answer say which specific tables, columns or metrics it was built from?

Partly
Quoted from Sigma’s docsReview the sources used by Assistant throughout your conversation.

Claude partly · GPT partly · Gemini partly
Grading standard

Named tables, columns or metrics attached to the answer, such as a field list or a citation shown with it. The text of a generated query is credited to the analytical-steps row, not this one, even though it names tables. Naming only the dataset does not count.

Can the AI analyze a CSV or spreadsheet a user uploads?

Yes
Quoted from Sigma’s docsTo ask ad hoc questions about your eval results, such as which cases regressed after your last instructions change, or to automate using a large language model (LLM) as a judge, add a Sigma agent to the Agent evaluation scoring workbook and add the AI_USAGE table and your eval cases table (uploaded as a CSV if you used a local file programmatically, or the input table if you used a UI-based approach) as data sources for the agent.

A user can give the product a CSV or spreadsheet and use the AI to analyze its contents.

Can the AI clean or reshape data while leaving inspectable transformation logic?

Yes
Quoted from Sigma’s docsThe formula assistant evaluates your description of calculations, data references, manipulations, and other context, then suggests a formula to achieve the desired output.
Source: help.sigmacomputing.com/docs/use-ai-with-formulas · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini partly
Grading standard

The AI can clean or reshape data and leaves transformation steps, code or another inspectable artifact behind.

Can the AI combine two or more data sources in one analysis?

Yes
Quoted from Sigma’s docs Sophisticated analysis of complex datasets: An agent can perform sophisticated analysis such as "Identify unused servers by analyzing the currently running applications and server inventory" by reasoning across multiple related data sources, even if those sources are in different connections.
Source: help.sigmacomputing.com/docs/sigma-agents · checked Oct 26, 2026 · quoted by GPT
Claude yes · GPT yes · Gemini yes
Grading standard

The AI joins or blends at least two sources, for example two databases or a database and an uploaded file. Tables in one database are one source, and analyzing an uploaded file on its own is the file-upload row.

Can the AI select and create a visualization suited to the analytical question?

Yes
Quoted from Sigma’s docsWhen Sigma Assistant includes a chart in its response, you can click Add to workbook to add it directly to the workbook canvas.
Source: help.sigmacomputing.com/docs/sigma-assistant-in-the-workbook · checked Oct 26, 2026 · quoted by Gemini
Claude yes · GPT yes · Gemini yes
Grading standard

The AI selects and creates a chart or table suited to the question, rather than only changing a visualization the user chose.

Can the AI identify what contributed to a change, with calculations a person can check?

Partly
Quoted from Sigma’s docsExtract factual information from your data, identify the drivers behind a metric, detect anomalies and get guided next steps, segment your data into meaningful groups, or ask questions that generate charts you can explore in a workbook.
Source: help.sigmacomputing.com/docs/ask-natural-language-queries-with-assistant · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: the built-in assistant breaks a change down into contributing segments or factors and shows the contribution of each, with the calculation a person can check, for example a table of segments with their share of the change. A key-driver function the assistant is documented to use counts; one only a user calls in SQL does not. Naming likely causes, or describing that a number rose or fell, without contributions is partly.

Can the AI produce a forecast and expose the assumptions behind it?

Partly
Quoted from Sigma’s docsAn agent can run forecasting calculations based on the contents of an input table and informed by policy documents in an external system, then present results in a structured format for review and approval.
Source: help.sigmacomputing.com/docs/sigma-agents · checked Oct 26, 2026 · quoted by Gemini
Claude partly · GPT partly · Gemini partly
Grading standard

The AI creates a forecast and exposes its horizon, inputs and assumptions so the result can be challenged. A forecast that does not expose its assumptions is partly. The AI itself must produce the forecast, so a classic forecasting feature it does not drive does not count, and a horizon with a confidence range but no stated inputs is partly.

Can the AI calculate and compare what-if scenarios, each with its changed assumptions stated?

Partly
Quoted from Sigma’s docs Perform scenario analysis for strategic planning: An agent can analyze possible scenarios that could affect the product supply chain by generating what-if scenarios based on user inputs and data, running scenarios using external models defined in Python code or stored procedures. When performing scenario analysis, the agent can state assumptions and uncertainty, and evaluate the output of a possible scenario compared with real outcomes provided in an input table.
Source: help.sigmacomputing.com/docs/sigma-agents · checked Oct 26, 2026 · quoted by GPT
Claude partly · GPT partly · Gemini partly
Grading standard

A user can define more than one what-if scenario with the AI, the changed assumptions of each scenario are stated explicitly, and the AI calculates results for each that can be compared side by side. A single what-if answer, or scenarios without stated assumptions or calculated results, is partly.

Does the answer expose data freshness or staleness to the user?

Not found
Nothing in the docs settles this.
Claude nothing found · GPT nothing found · Gemini nothing found
Grading standard

The answer exposes the age or last-refresh time of the data it used, so stale output is visible at the point of use. Freshness shown with the answer through the data source's own indicator, for example a "last refreshed" badge on the dataset the answer used, is partly.

Chart logic 4

Can the built-in assistant read the calculation behind a chart or table in BI content?

Yes
Quoted from Sigma’s docsSigma’s formula assistant uses AI to write new formulas, correct formula errors, and explain existing formulas applied to elements in workbooks and data models.

An outside agent can create BI content through the vendor's interface, the way it would open a pull request. Analyst work only is partly.

Can a user share AI-created BI content with named users or groups, with each viewer seeing only what their own permissions allow?

Yes
Quoted from Sigma’s docs If you use OAuth to authenticate users to a data source, Sigma runs the query using the viewer's identity in the data platform.

Claude partly · GPT yes · Gemini yes
Grading standard

yes: AI-created BI content can be shared with named users or groups and each viewer sees only the data their own permissions allow (results evaluated as the viewer). Sharing that shows the author's results to everyone is partly. An asset counts as AI-created only if the AI built it, not if a person pasted AI-generated SQL into it.

Can permitted users find colleagues' saved analytical assets through workspace-wide browse or search?

Yes

Built-in agents 7

Can you save a built-in assistant with its own instructions, data and permissions, and let colleagues reuse it?

Yes
Quoted from Sigma’s docsInstructions and data sources provide the context, while actions and agents configured in your data platform provide the tools for an agent to take action or enrich insights.
Source: help.sigmacomputing.com/docs/sigma-agents · checked Oct 26, 2026 · quoted by Gemini
Claude yes · GPT yes · Gemini yes
Grading standard

An assistant someone configures once, with its own instructions, data and permissions, that colleagues can then reuse.

Can the product’s AI or an agent rerun a defined analysis on a schedule or trigger and deliver a fresh result or alert?

Yes
Quoted from Sigma’s docsYou can call an agent as part of an automated action sequence to automate multi-step workflows that gather data, generate structured output, and trigger downstream actions without any user interaction.
Source: help.sigmacomputing.com/docs/build-agents · checked Oct 26, 2026 · quoted by Gemini
Claude yes (preview) · GPT yes (preview) · Gemini yes
Grading standard

The product’s AI or an agent can rerun a defined analytical task on a schedule or trigger and deliver a fresh result or alert without a person present. An ordinary report or dashboard schedule that the AI or an agent does not run does not count, and an AI that only sets up such a schedule is partly.

Can an agent do something beyond answering, write back, notify, call another system?

Yes
Quoted from Sigma’s docsFor specific customers represented in the survey data, the agent can send Slack or Microsoft Teams messages, such as to notify customer success managers about accounts that might be a churn risk.
Source: help.sigmacomputing.com/docs/sigma-agents · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

yes: a built-in agent can, on its own, cause a named side effect outside the analytics content: send a message or notification, call a webhook or another system, or write data to a destination. Writing to the product's own dashboards or notebooks does not count. Generating code a person must then run is partly.

Does the documentation describe how an agent hands a task back to a person when it cannot proceed?

Partly
Quoted from Sigma’s docsIf your question is vague, Assistant might prompt you to clarify what you're asking for before responding.
Source: help.sigmacomputing.com/docs/ask-natural-language-queries-with-assistant · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: a built-in agent that cannot finish a task stops and hands it to a person, with the hand-off documented (a notification, a review queue, a pause awaiting a decision). Asking the user a clarifying question during a conversation is partly. Silence is nothing found.

Can a customer configure one agent to delegate a bounded analytical task to another named agent?

Yes
Quoted from Sigma’s docsA Sigma agent can function as an orchestrator, instructing a set of warehouse agents to perform narrowly scoped tasks on specific data sources, and summarizing the responses to inform further analysis or take action in Sigma.
Source: help.sigmacomputing.com/docs/build-agents · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

A customer can configure one agent to delegate a bounded analytical task to another named agent with explicit tools and permissions. Hidden implementation subagents do not count.

Can the built-in assistant connect out to external tools or MCP servers you configure?

Yes
Quoted from Sigma’s docsYou can use MCP servers with Sigma agents to add context to your conversation, retrieve ad hoc data, or permit the agent to take action in third-party tools.
Source: help.sigmacomputing.com/docs/configure-mcp-connectors · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT yes · Gemini yes
Grading standard

The vendor documents attaching an outside capability to its own AI. Shipping an MCP server is the opposite direction and a different row.

Can the product's AI find and fix BI content affected by a change in the data or its definitions?

Partly
Quoted from Sigma’s docsYou can use the assistant to correct formulas in existing columns (typically indicated by Incomplete formula, Invalid Query, or Unknown column cell values) or correct a manually entered formula when adding a new column.
Source: help.sigmacomputing.com/docs/use-ai-with-formulas · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

When a column is renamed, a table changes or a shared definition is edited, the product's AI or a built-in agent identifies the BI content affected and repairs it or flags it for an owner. yes: both finding the affected content and repairing or flagging it are documented for the AI. Impact analysis a person runs, with no AI involvement, does not count; the AI fixing one broken chart a user points it at is partly.

Generated apps 4

Can the built-in assistant read a generated app?

Evaluation & correctness 5

Can you test whether the built-in assistant's answers are right, a saved set of cases, a rubric, or a judge?

No
Quoted from Sigma’s docsYou can run your agent evaluations in the Sigma UI using input tables to define and record the evaluations.
Source: help.sigmacomputing.com/docs/build-agent-evaluation-suite · checked Oct 26, 2026 · quoted by Claude
Claude no · GPT no · Gemini yes
Grading standard

A saved set of questions with expected answers, a rubric, a model judging the output, or a run you can repeat after a change, applied to the built-in assistant's answers. A thumbs-up button collects opinions and does not count.

Can you pin which model version the built-in assistant uses?

No
Quoted from Sigma’s docsYou cannot choose which model Sigma uses, and Sigma might update the supported models over time.
Source: help.sigmacomputing.com/docs/supported-ai-models · checked Oct 26, 2026 · quoted by Gemini
Claude partly · GPT no · Gemini no
Grading standard

yes: an admin or user can choose a specific named model version for the built-in assistant and it stays on that version until changed. Choosing among models or providers without a fixed version is partly. The vendor managing the model with no customer choice is no. Provider choice for data location belongs to KEY, not this. Identical answers are not required.

Can you preserve the inputs, configuration and logic needed to reproduce or audit a built-in assistant answer?

Partly
Quoted from Sigma’s docsToggle between all conversations and agent conversations, or view details about a full conversation, including user input and AI output, user name, input and output tokens, total turns and duration of the conversation, model used and product that the conversation took place in.

Grading standard

The product preserves the inputs, configuration, model and analytical logic needed to reproduce or audit an answer. Byte-for-byte model determinism is not required. Kept chat history with the generated query is partly; yes needs the inputs, configuration, model and logic. A record that keeps the model, the prompt and the generated query but not the data snapshot or configuration is partly.

Does a person’s correction to a built-in assistant answer change its later answers, and does the documentation say how far that reaches?

No
Quoted from Sigma’s docsTo help the agent remember important context from conversations, add an input table to your workbook and create an action tool for the agent to use.

The documentation says a correction a person makes to a built-in assistant answer changes the assistant’s later answers, and says how far it reaches (that user, a team, everyone using the data). A correction documented to affect later answers with no stated reach is partly. A feedback thumb that only rates an answer or files a ticket is not this.

Does the built-in assistant answer consistently with the product's certified or governed content?

Partly
Quoted from Sigma’s docs The known validity of the data: For example, if a data model has an "endorsed" badge applied, Assistant is more likely to use that data source. Similarly, if someone in your organization has created and shared metrics and data models, Assistant is more likely to select one of those when answering rather than using a table directly from your connected data platform.

Claude partly · GPT partly · Gemini partly
Grading standard

When a question is already answered by certified BI content or a governed metric, the product makes the assistant use that same definition, or tells the user when its answer departs from it. yes: the documentation says the assistant is bound to or checked against certified content or governed metrics, and that a mismatch is prevented or flagged. Using the semantic layer when one exists, with no statement about certified content or mismatches, is partly (that alone is the shared-definitions read row, M_IR). A "verified" badge on some answers with no rule tying answers to certified definitions is partly.

Administration & observability 6

Per-user or per-team attribution of AI usage. A single tenant-wide total is not this.

Are the built-in assistant’s actions logged with the user and the analytical objects affected?

Yes
Quoted from Sigma’s docsFor example, for a Trace Name of database_execute_query, includes the SQL statement run for the tool call and the title shown to the user in the chat (if applicable) during the tool call.

The product records what the built-in assistant did, the prompt or query it ran and the objects it touched, attributable to the user who asked. A general product audit log that does not distinguish assistant activity is insufficient.

Can an administrator enable or disable AI features for particular users, groups or workspaces?

Yes
Quoted from Sigma’s docsControl who can access different AI features by enabling feature permissions on different account types assigned to users:

Grading standard

A documented control that turns AI features on or off for a subset of the tenant. An account-wide on/off with no granularity is partly; a setting that only governs which model is used is MODELPIN, not this.

Can the built-in assistant’s change to a governed analytical asset be held for human approval before it takes effect?

Partly
Quoted from Sigma’s docsWhen you access a workbook draft, Sigma Assistant can operate in one of two specialized modes: plan or build.
Source: help.sigmacomputing.com/docs/use-ai-to-build-dashboards-and-apps · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: the built-in assistant's change to governed BI content or shared definitions is held until a named person or role approves it, or a policy routes the assistant's write to an approver who is a different person or role from whoever asked. A prompt shown only to the requester is partly. A draft the same user later publishes, or a general publishing workflow the assistant is not documented to enter, is partly. A user accepting or rejecting the assistant's suggestion to their own work is not approval.

Data handling & AI governance 6

Can the customer control where model inference occurs?

Yes
Quoted from Sigma’s docs To connect to an AI model hosted by your data platform, see Configure a warehouse-hosted model as AI provider. When you choose the option to configure a warehouse-hosted model, your data is managed fully in your data platform.
Source: help.sigmacomputing.com/docs/configure-ai-features-for-your-organization · checked Oct 26, 2026 · quoted by GPT
Claude yes · GPT yes · Gemini yes
Grading standard

The customer controls where inference occurs. A model running in the customer's cloud, warehouse or tenant earns yes; a documented choice of region or provider endpoint, or a bring-your-own-key path where the documentation says where the provider processes the request, earns partly. Vendor-hosted inference that the documentation says the customer cannot choose or move earns no. Supplying a key does not by itself say where inference runs, and documentation that only states where processing happens, with no customer choice, belongs to the residency row. A choice that applies to only some of the product's AI features is partly.

Do your existing row-level security and column permissions apply to what the BUILT-IN assistant returns?

Yes
Quoted from Sigma’s docsFor example, if row-level security or column-level security is applied to a data source, Sigma Assistant only works with data that you have access to.
Source: help.sigmacomputing.com/docs/ask-natural-language-queries-with-assistant · checked Oct 26, 2026 · quoted by Claude
Claude yes · GPT partly · Gemini yes
Grading standard

yes: the documentation states that the built-in assistant answers under the asking user's identity, so existing row-level and column-level rules apply. Dataset-level or object-level permissions only, or row and column rules that some AI surfaces documentedly bypass, are partly.

Does the product documentation say which services receive AI prompts or data, and what they receive?

Partly
Quoted from Sigma’s docs When you configure an External AI Model , Input Data , Prompts , Customer Data , and User Information used for AI-enabled features will be sent to that External AI Model under your organization’s API credentials and will be handled per that External AI Model’s terms and your configuration.
Claude partly · GPT partly · Gemini partly
Grading standard

yes: names the services that receive AI prompts or data, what they receive, and how long it is kept. Missing any one of the three is partly. A subprocessor list is not required; one published only on a separate trust or legal site is outside this documentation, so its absence here is nothing found, not no.

Does the product documentation say where AI requests are processed and stored?

Partly
Quoted from Sigma’s docsSigma uses the global endpoint to access the supported model.
Source: help.sigmacomputing.com/docs/manage-external-ai-integrations · checked Oct 26, 2026 · quoted by Claude
Claude partly · GPT partly · Gemini partly
Grading standard

yes: the product documentation states the regions where AI requests are processed and where AI data is stored, for all of the product's AI features. A subprocessor or trust page counts if it is part of the product documentation. Regions for some AI features only, or processing without storage, is partly.

yes: an administrator can enforce, across the workspace or tenant, a limit on which data the assistant may use, separate from user permissions. A scope the author of each agent sets, or a scope the documentation says is not a security boundary, is partly.

Agent access 13

Can an outside agent act under an identity or token scoped narrower than the human's own access?

Yes
Quoted from Sigma’s docsImpersonating users allows admins to act as a user and view, edit, and access Sigma resources based on the user's account type.

yes: an outside agent can act under an identity or token scoped narrower than the human's own access (read-only, limited objects or limited tools). Acting as the full human identity is partly. Shared broad credentials do not count.

Can an outside agent traverse the upstream sources and transformations behind a number?

Partly
Quoted from Sigma’s docsAlso fires for usage of the Sigma MCP describe tool to view the schema / DDL of a data model or workbook.

Grading standard

yes: an outside agent can follow a number to its upstream sources and transformations through a documented lineage interface. Reading the SQL of a view or model and inferring its sources is partly. A link from an answer back to its underlying source is partly. A description that names no upstream source or transformation does not count.

Are an outside agent’s actions logged with its identity and the analytical objects affected?

Yes
Quoted from Sigma’s docsAlso fires for Sigma MCP Server requests.

Grading standard

The product records actions taken by an outside agent, tied to its delegated identity and affected analytical objects. A general user activity log is insufficient.

Can an outside agent’s change to a governed analytical asset be held for human approval?

Partly

Grading standard

yes: an outside agent's change to governed BI content or shared definitions is held until a named person or role approves it, or an MCP or agent policy routes the agent's write to an approver who is a different person or role from whoever started the agent. A prompt shown only to the requester is partly. A draft the same user later publishes, or a general Git pull-request workflow not documented for agent changes, is partly.

Can a reviewer see a diff of what an outside agent changed in a governed analytical asset?

Partly
Quoted from Sigma’s docsYou can use the version and edit history to review drafted changes, compare or revert to older published versions, identify who on your team made a specific edit or set of changes, or identify which version is tagged with a specific version tag.

A reviewer can see a before/after diff of changes an outside agent made to a governed analytical asset. A generic publish or change diff is partly; yes needs the documentation to show it covers changes made by an outside agent.

Can an outside agent’s change to a governed analytical asset be rolled back?

Yes
Quoted from Sigma’s docsTo return a workbook to a previously published version, or to a specific change in the workbook version history, restore a previous change or version to draft.

Does the vendor support an MCP server with documented authentication for outside agents?

Yes
Quoted from Sigma’s docsThe Sigma MCP server allows you to use natural language to interact programmatically with your Sigma organization using Model Context Protocol (MCP) tools.

Grading standard

A vendor-supported MCP server gives outside agents access to the customer’s analytical objects or data, with documented authentication and no customer-built middleware. A vendor-supported server the customer operates, or one in preview, earns partly. A server built by the community or by customers, or one that only searches documentation, does not count.

Can an outside agent list what exists, dashboards, metrics, tables, without being told what to look for?

Yes

A documented way to enumerate objects, not just fetch one by id. Reading a named dashboard is a different row; this is finding out the dashboard is there.

Does the vendor document how an outside agent authenticates, a service account, a token, or acting on behalf of a user?

Yes
Quoted from Sigma’s docsThe Sigma MCP server authenticates to Sigma using OAuth.

A named credential type for programmatic access. Whose permissions apply is a different row; this is how the agent gets in at all.

Does the vendor publish skills or packaged instructions that teach an outside agent to use the product?

Yes
Quoted from Sigma’s docsYou can use agent skills published by Sigma to provide reference materials and instructions to your AI assistants.

A vendor-published skill, plugin or instruction pack (for example a SKILL.md or an agent plugin) that an outside coding agent loads to use the product well. Documentation of an MCP server alone is the MCP server row, not this.

Is there a command-line tool documented for use by outside agents?

yes: the product documents a direct path from a calculation written for one chart or analysis to a maintained shared definition, without a developer rewriting it. A path that needs the calculation re-expressed by a developer (for example in a modeling language) is partly. Reusing logic that already exists as a shared definition, macro or snippet does not count.
