In short: Snowflake Cortex Analyst is an impressive text-to-SQL service — but it requires all your business data to already reside in Snowflake. For companies without an existing cloud data warehouse, that means months of preparation and ongoing costs in the thousands before a single question is asked. oneAgent connects directly to your existing systems — Shopware, SAP, CRM — and delivers answers from day one. No data warehouse, no ETL pipelines, starting at EUR 25 per user per month.
What Is Snowflake Cortex Analyst?
Snowflake Cortex Analyst is an AI-powered natural-language query service built into the Snowflake platform. Generally available since late 2025, Cortex Analyst translates natural-language questions into SQL queries and executes them against your Snowflake database. Under the hood, the service uses models from Meta (Llama) and Mistral, specifically optimized for SQL generation.
The approach is technically sophisticated: you define a Semantic Model in YAML format that describes your tables, columns, and business logic. Cortex Analyst uses this model to correctly interpret user questions and translate them into precise SQL. Snowflake reports an SQL accuracy of approximately 90 percent — a solid number that drops noticeably for complex JOINs and trend analysis.
Important to understand: Cortex Analyst is not a standalone product. It is a feature within Snowflake. This means you must already be a Snowflake customer, your data must reside in Snowflake, and you need a manually created and maintained Semantic Model. Cortex Analyst does not connect to external data sources — there are no connectors to SAP, Shopware, or your CRM.
The result of a query is a SQL table. For visualizations, you need an additional tool such as Streamlit or Tableau. Cortex Analyst itself does not produce charts or graphics.
The Fundamental Difference: Data Warehouse vs. Direct Connection
The core difference between Snowflake Cortex Analyst and oneAgent is not AI quality — both systems deliver precise answers to data questions. The difference lies in architecture and prerequisites.
Cortex Analyst: Data Must First Move to Snowflake
Before Cortex Analyst can answer a single question, your business data must be in Snowflake. In practice, that means:
- Build ETL pipelines: Extract data from your source systems (ERP, CRM, e-commerce), transform it, and load it into Snowflake
- Create a Semantic Model: A YAML-based model describing your tables and business logic — manually created, with regular maintenance (Snowflake recommends monthly audits)
- Operate Snowflake: Ongoing costs for compute, storage, and credits
For companies that already run a Snowflake data warehouse, Cortex Analyst is a logical addition. For everyone else, it means weeks to months of preparation before the first question is answered.
oneAgent: Direct Connection to Your Systems
oneAgent takes a fundamentally different approach. With over 550 native connectors, oneAgent connects directly to your existing systems — Shopware, SAP, Microsoft Dynamics, Salesforce, DATEV, databases, and cloud services. No data warehouse required, no ETL pipelines, no Semantic Model.
Setup takes days, not months. During onboarding, your data sources are connected, access rights are configured, and initial queries are tested. Your employees ask questions in a chat interface — and receive answers with visualizations.
What Does Snowflake Cortex Cost vs. oneAgent?
The costs of Cortex Analyst are difficult to predict. Snowflake charges in credits, and consumption depends on query complexity, data volume, and warehouse size.
Snowflake Cortex Analyst Cost Structure
- Cortex Analyst credits: 6.7 credits per 100 messages (~USD 0.20 per question)
- Warehouse compute: Additional costs for SQL execution (variable)
- Snowflake storage: Ongoing costs for stored data
- Snowflake platform: Base costs for the Snowflake account (often several thousand EUR/month)
Realistic Scenario: 10 Users, 10 Questions per Day Each
| Cost Item | Snowflake + Cortex Analyst | oneAgent |
|---|---|---|
| AI queries (3,000 questions/month) | ~USD 600 (~EUR 560) | Included |
| Warehouse compute | ~EUR 200–400/month | Included |
| Snowflake platform + storage | ~EUR 2,000–5,000/month | EUR 0 |
| User licenses | Included in Snowflake costs | EUR 250/month |
| Monthly total | ~EUR 3,000–6,000 | EUR 250 |
| Annual total | ~EUR 36,000–72,000 | EUR 3,000 |
| Onboarding / setup | ETL + Semantic Model (thousands of EUR) | From EUR 1,500 (one-time) |
Cost Trap: Unpredictable Queries
A documented case illustrates the risk: a single query on 1.18 billion records cost over USD 5,000. Snowflake does not offer native resource monitors for Cortex Analyst — cost control is entirely the customer's responsibility.
With oneAgent, you pay EUR 25 per user per month. Flat. No credits, no variable compute costs, no surprises.

Where Is Snowflake Cortex the Better Choice?
We believe in honest comparisons. There are clear scenarios where Cortex Analyst is the right decision.
1. You Already Run a Snowflake Data Warehouse
If your data is already consolidated in Snowflake — with clean tables, documented schemas, and running ETL pipelines — then Cortex Analyst is an elegant addition. The data is there, the infrastructure is in place, and you are activating an additional service.
2. Your Data Team Wants a SQL Accelerator
Cortex Analyst is not a self-service tool for business departments — it is a productivity booster for people who understand SQL. If your analysts want to reach results faster without writing every query manually, Cortex Analyst is a powerful tool.
3. You Need Maximum Control over AI Interpretation
The Semantic Model in Cortex Analyst gives you precise control over how the AI interprets your data. You define exactly which tables, columns, and business rules the service may use. For complex data landscapes with ambiguous terms, this can be an advantage.
4. You Work with Very Large, Structured Datasets
Snowflake is built for massive data volumes. If you regularly analyze billions of rows and have compute costs under control, Cortex Analyst provides direct access to the full power of Snowflake.
5. Your Organization Is Investing Long-Term in the Snowflake Platform
If Snowflake is and remains your strategic data platform, the investment in Semantic Models and the integration of Cortex Analyst into your existing workflows pays off.
Where Is oneAgent the Better Choice?
1. You Do Not Have a Cloud Data Warehouse
For the majority of mid-market companies, the reality is: data resides in SAP, Shopware, a local ERP, a SQL database, and perhaps Excel. Building a data warehouse takes months and costs five figures. oneAgent connects directly to these systems — no intermediate layer.
2. Your Users Are Business Departments, Not Data Engineers
Cortex Analyst is aimed at technically proficient users who can interpret SQL results and know what a Semantic Model is. oneAgent is built for sales managers, procurement specialists, controllers, and executives — people who want answers, not SQL tables.
3. You Need Visualizations, Not Just Tables
Cortex Analyst returns SQL results as tables. For charts, you need Streamlit or Tableau — an additional tool with additional complexity. oneAgent delivers automatic visualizations directly in the chat interface.
4. Cost Predictability Matters
With Snowflake, costs can fluctuate significantly depending on query complexity. A poorly formulated query on a large dataset can generate three- or even four-figure costs. With oneAgent, you pay EUR 25 per user per month — regardless of how many questions are asked.
5. Deterministic Results Are Business-Critical
Cortex Analyst achieves approximately 90 percent SQL accuracy — a solid number, but a 10 percent error rate means every tenth query may return incorrect results. The deterministic AI layer in oneAgent translates questions into exact database queries — the result is always traceable and correct.
6. You Want to Start in Days, Not Months
Onboarding with oneAgent typically takes a few days. Connectors are set up, access rights are configured, initial queries are tested. No ETL project, no Semantic Model creation, no months-long implementation.

Frequently Asked Questions
Can oneAgent Query Data from Snowflake?
Yes. oneAgent offers a native Snowflake connector. If you use Snowflake as one of your data sources, oneAgent can query that data alongside your other systems — SAP, CRM, Shopware, and Snowflake in a single answer.
Do I Need to Build a Semantic Model for Cortex Analyst?
Yes. The Semantic Model is not an optional add-on — it is a prerequisite. It is manually created in YAML format and describes your tables, columns, and business logic. Snowflake recommends a maximum size of 1 MB and 3 to 5 tables with 10 to 20 columns. When your data structures change, the model must be manually updated.
How Accurate Is Cortex Analyst with German Queries?
Snowflake's benchmarks were conducted exclusively in English. Cortex Analyst does understand German questions, but SQL accuracy is typically below the English benchmark of approximately 90 percent. Compound words, industry-specific terminology, and specialized business terms in German can lead to inaccurate interpretation.
What Happens If a Cortex Analyst Query Becomes Very Expensive?
Snowflake does not offer native resource monitors for Cortex Analyst. The cost of a single query depends on data volume and warehouse size. In a documented extreme case, a single query cost over USD 5,000. You must implement cost controls yourself — for example, through warehouse timeouts or query tags.
Is oneAgent Also Suitable for Large Data Volumes?
Yes. oneAgent processes large datasets efficiently because queries run directly against your source systems. The deterministic AI layer ensures correct results regardless of data volume. For organizations with billions of rows in a centralized data warehouse, Snowflake may offer advantages in raw query performance.
Can I Switch from Snowflake Cortex Analyst to oneAgent?
Yes. Since oneAgent connects directly to your source systems, no data migration project is necessary. You connect your existing systems, and oneAgent is ready to use. Snowflake data can continue to be used in parallel — it is not an either-or decision.
