Cohere Command R2 is an enterprise-focused large language model featuring a dedicated structured-data reasoning mode that can generate and execute SQL, Python, and R code directly against connected databases. It is available through Cohere's API as well as private deployments on AWS and Azure, making it suitable for organizations with strict data governance requirements. The model is purpose-built for business intelligence and data analysis workflows, enabling users to query complex datasets using natural language.

One SQL semantic layer so AI agents stop hallucinating your KPIs

Metrics SQL is a SQL-based semantic layer from Rill Data that solves a specific and painful problem: AI agents that query your data warehouse tend to hallucinate aggregation logic, producing metrics that look plausible but are mathematically wrong. Metrics SQL lets analysts define business metrics once — revenue, MAU, conversion rate, ROAS — in a governed definition layer, and then exposes those definitions as queryable SQL tables. Every dashboard, notebook, and AI agent resolves from the same source. The technical approach is elegant: rather than inventing a new DSL, Metrics SQL extends SQL itself. An agent that knows SQL can query `SELECT * FROM metrics.weekly_revenue` and get correctly computed numbers without needing to know how revenue is defined, which tables it joins, or how edge cases like refunds are handled. The semantic layer intercepts the query, applies the governed definition, and returns correct results. The implications for AI-native data stacks are significant. Currently, one of the biggest failure modes for AI analysts and BI agents is inconsistent metric computation — different agents or dashboards produce different numbers for 'revenue' because they implement aggregation logic differently. Metrics SQL addresses this at the infrastructure level, not by improving agent prompting.
Reviewer scorecard
“Native SQL and code execution baked directly into the model is a massive DX win — no more duct-taping text-to-SQL pipelines together with fragile prompt engineering. The private deployment option on AWS and Azure is the real killer feature for enterprise shops that can't let data leave their VPC. This is the kind of pragmatic, production-ready tooling the space desperately needed.”
“We've been burned by data agents that invent their own GROUP BY logic and produce wrong numbers that look right. Metrics SQL solves this at the infrastructure level — define revenue once, have every agent query the same definition. The SQL-native interface means no new tools for agents to learn; they just use the tables.”
“"Generates and executes code against your database" should come with flashing red warning lights — hallucinated SQL running on production data is a liability nightmare waiting to happen. Cohere hasn't been transparent about benchmark accuracy on real-world, messy schemas, and enterprise pricing opacity makes it nearly impossible to evaluate ROI before you're already locked in. I'd wait for independent audits before letting this anywhere near critical data infrastructure.”
“The value here is only as good as how well-maintained your metric definitions are — if analysts don't keep them updated, agents query stale or wrong definitions and you've added a layer of false confidence. Adopting a semantic layer also creates vendor dependency; migrating away from Rill's cloud later is a real switching cost. For smaller teams without dedicated data engineering, maintaining a semantic layer is overhead.”
“Unless you live and breathe SQL and data pipelines, Command R2 is just not built for you — it's a deeply technical tool aimed squarely at data engineers and enterprise IT teams. There's no intuitive interface, no visual output layer, and no creative use case that justifies the complexity. Creatives wanting AI-powered data storytelling should look elsewhere for something with a friendlier front end.”
“I rely on AI to pull weekly performance data, and the number of times it's given me different 'correct' answers for the same metric is maddening. Having a single governed source that every AI query resolves against means I can trust the numbers I'm making decisions on. That trust is worth a lot.”
“This is a meaningful step toward the long-promised vision of natural language as a universal interface for data — and Cohere's enterprise-first deployment model signals they understand that trust and control are the real blockers to adoption, not capability. Embedding code execution directly in the model collapses the analyst-to-insight loop in a way that could fundamentally reshape how businesses consume data. The trajectory here is exciting, even if the edges are still rough.”
“Data governance and AI agents are on a collision course. As more business decisions are delegated to AI, the correctness of KPI computation becomes load-bearing — a hallucinated revenue figure that influences a product decision is a serious failure mode. Metrics SQL represents a class of infrastructure that will become mandatory as AI takes on more analytical work.”
