The promise of agentic analytics — AI systems that understand natural language, query data, generate insights, and even take actions — is incredibly powerful.
However, as many data leaders will attest, the excitement often fades once these systems meet real production data, real business logic, and real users.
As Tellius notes in “10 Battle Scars from Building Agentic AI Analytics,” the biggest challenges appear not in demos, but in production environments.
One of the most common root causes of failure is missing semantic awareness — raw, messy data, vague business definitions, and unclear logic that derail even the smartest models.
In this post, we’ll:
- Explore why agentic analytics struggle in real-world environments
- Highlight key failure modes seen across the industry
- Offer a practical checklist for practitioners

What is Agentic AI Analytics?
“Agentic analytics” refers to AI-driven systems where autonomous agents interpret natural-language input, plan multi-step analytical workflows (querying data, analysing, explaining), and deliver insights — or even trigger actions.
For example:
A user asks, “Why did Q3 revenue drop in APAC?”
The agent interprets the question, identifies the region, selects the correct metric, applies the relevant time window, runs a root-cause analysis, and presents both the narrative and visuals.
Delivering this in production, however, is far harder than building a simple “LLM-to-SQL” demo.
As Tellius puts it:
“Chat-based analytics requires way more than just an LLM turning text into SQL.”
In practice, most failures stem from hidden complexity, scalability issues, poor governance, and lack of semantic grounding — challenges that only surface when prototypes meet real enterprise data.
Why Production Data and Semantics Trip You Up
Moving from a demo to production exposes the real challenges of agentic AI analytics — messy data, complex schemas, and unclear business meaning.
Here are the key reasons these systems often fail when confronted with enterprise-scale data:
1. Complexity of real schemas and business definitions
Demo datasets are simple; production data isn’t. Enterprises often have hundreds of tables and overlapping metrics.
Without a governed semantic layer, agents choose wrong joins, mix definitions, and misinterpret context.
Tellius notes that enterprise datasets average 300+ columns, compared to just 28 in benchmark datasets like Spider.
2. Ambiguity in natural language input
Users ask ambiguous questions such as “top customers by region” or “area performance”.
Without context, the agent must guess — and when it guesses wrong, trust erodes.
“Ambiguity is when user language admits multiple valid interpretations … so the system can’t confidently pick one.” — Tellius
3. Lack of deterministic planning and reproducibility
LLM “chain” frameworks may appear fast but often hide retries, implicit defaults, and opaque logic.
In production, you need repeatable, traceable results — same input → same output — every time.
4. Performance, latency, and cost issues
Unbounded AI-generated queries often scan massive datasets, resulting in slow responses and high compute costs.
“AI-generated queries tend to scan far more data than human-written ones … total processing reaches 6–7 seconds … killing interactive use cases.” — Tellius
5. Poor observability and lack of trust
When users see a number without understanding how it was derived, they lose confidence.
Enterprise analytics must be glass-box, not black-box — showing joins, filters, and metric logic.
6. Missing or immature semantic layer
The semantic layer provides the structure and meaning that AI agents depend on.
As Cube notes:
“The semantic layer provides the necessary constraints and context that enable AI agents to operate reliably and deliver trustworthy insights.”
Without it, the agent operates blindly — disconnected from true business meaning.
So – What Does Good Look Like?
If you’re planning an agentic analytics deployment, here are the essential components that define a successful, production-ready approach:
Build a governed semantic layer
Define all metrics, dimensions, hierarchies, synonyms, and business views.
Include ontologies (entities like Customer, Product, Region) and relationships.
Document business definitions (e.g., what “revenue” or “active customer” means).
A strong semantic layer grounds agents in business meaning and consistency.
Split the stack: intent → plan → validator → execution
Structure your workflow into clear, auditable steps:
- Natural language → intent/entities/time filters
- Planner → generates a typed plan (AST)
- Validator → checks the plan against schema and policy before execution
As Tellius advises: “Split the stack … keep language for explanations; keep logic deterministic.”
Handle ambiguity and user clarification
When a term can map to multiple meanings, the agent should ask:
“By area, do you mean Region or Territory?”
Store user preferences so future queries resolve automatically.
Ensure determinism and reproducibility
Resolve relative time references (e.g., “last quarter”) into explicit ranges.
Guarantee that identical inputs always yield the same plan and results.
Use plan fingerprinting and result caching for traceability and performance.
Monitor performance, latency, and cost
Define budgets and service-level targets for each stage — planning, compilation, execution.
Detect and mitigate heavy queries automatically; leverage caching and fallback options.
Provide transparency and audit trails
Each result should include metric definitions, time ranges, lineage (tables and joins), and applied policies.
Log everything: run IDs, semantic versions, cache hits, and fallback paths.
Start small and domain-scoped
Avoid launching across the entire warehouse at once.
Focus on a single domain (e.g., Sales or Marketing) to refine your semantic model and agent performance early.
Keep a human in the loop until trust is established
For high-impact queries, include human review or confirmation.
Use user feedback to refine synonyms, business rules, and workflows over time.
Typical Pitfalls (and How to Avoid Them)
| Pitfall | What Happens | What To Do Instead |
|---|---|---|
| Relying on generic “chains” frameworks without control | Hidden retries, opaque state, debugging becomes a nightmare. | Build a thin, auditable execution layer and validate every step. |
| Ignoring semantics and using raw schema | Agents misselect metrics or columns and produce incorrect logic. | Build a semantic dictionary and allow only valid metric–dimension pairs. |
| Letting prompt engineering drive execution logic | Small wording changes cause wildly different joins or time windows. | Separate prompt (intent) from plan; keep execution logic deterministic. |
| Rolling out full warehouse scope too early | Accuracy drops, latency increases, and costs escalate. | Start with one domain and one user persona; refine before scaling. |
| No transparency or auditability | Users lose trust and adoption stalls. | Provide “why” with each result, show lineage, and enable feedback loops. |
| Poor performance engineering | Even correct results arrive too slowly — users lose confidence. | Set latency SLOs, monitor P95/P99 performance, cache aggressively, and limit data scans. |
Conclusion
Agentic AI analytics hold immense promise — from conversational insights to automated workflows and faster decision-making.
But the gap between a working demo and a reliable, production-grade system is vast.
As Tellius and others have shown, success depends on getting the fundamentals right:
semantic grounding, governance, deterministic execution, performance engineering, and transparency.
If you’re building or deploying analytics agents, don’t just ask “Which LLM should we use?” — ask:
- Does the agent truly understand our business semantics?
- Can it deliver repeatable, auditable results?
- Will it scale with performance and trust built in?
The answer lies in strong semantic layers, transparent workflows, and continuous observability.
Get these right, and agentic analytics evolve from hype to dependable, enterprise-grade intelligence.

Key Takeaway
- Agentic AI analytics promise conversational, automated insights — but often fail in production due to missing semantics, governance, and performance discipline.
- Production data is messy and complex: hundreds of tables, inconsistent definitions, and ambiguous business terms derail naive LLM-to-SQL systems.
- Ambiguity kills trust: business questions like “top customers by region” require disambiguation and consistent metric definitions.
- Determinism and reproducibility are critical — same input must yield the same plan, and users must see how results were derived.
- Performance and cost constraints matter — unbounded AI-generated queries can cause latency spikes and high compute costs.
- The semantic layer is non-optional: it provides the business meaning, metrics, hierarchies, and relationships that ground agents in reality.
- Governed architecture wins: split the workflow into clear stages — intent → plan → validator → execution — for transparency and control.
- Build trust through visibility: show metric definitions, joins, filters, and lineage in every response; log and version everything.
- Start small and domain-focused: begin with one business area (e.g., sales or marketing) to refine semantics and performance before scaling.
- Human-in-the-loop review remains vital early on — use feedback to tune synonyms, logic, and guardrails.
- Avoid common pitfalls: lack of observability, poor performance tuning, overreliance on “chain” frameworks, or skipping semantic modeling.
Bottom line:
Agentic AI analytics only succeed when semantic grounding, governance, performance engineering, and transparency are built in from day one.
With these foundations, AI agents move from hype to trusted, enterprise-grade analytics systems.
