The Problem: AI Meets Structured Enterprise Data#
Large Language Models excel at reasoning over unstructured text, but struggle when they need access to structured, tabular data. Traditional RAG systems work well with documents and embeddings, but what happens when your AI agent needs to:
- Look up customer information by ID from your CRM database
- Query product catalogs with specific filters and availability
- Access financial records based on date ranges and categories
- Retrieve inventory data by location, SKU, and real-time status
Until now, you'd need complex custom APIs, manual data formatting, or fragile pipeline orchestration. Not anymore.
Introducing pxt.retrieval_udf(): Database Tables as AI Tools#
Pixeltable's new retrieval_udf() function transforms any data table into an AI-queryable tool with just one line of code. Your LLMs can now directly query structured enterprise data using natural language, while maintaining the precision and performance of native database operations.
This breakthrough bridges the gap between AI infrastructure and enterprise data systems, enabling true AI-native data access without compromising on security or performance.
How It Works: Three Simple Steps#
The magic of turning database tables into AI tools happens in three simple steps:
Step 1: Create Your Data Table#
Step 2: Convert Table to AI Tool#
That's it! Your database table is now an AI tool that any LLM can use.
Step 3: Use with Any LLM Provider#

Beyond Basic Retrieval: Hybrid AI Systems#
retrieval_udf() integrates seamlessly with Pixeltable's broader AI infrastructure capabilities, enabling sophisticated hybrid systems that combine multiple AI approaches:
This hybrid approach is particularly powerful for enterprise RAG systems where you need both semantic understanding and precise data retrieval.
Getting Started with AI Database Integration#
Ready to give your AI agents native access to structured data? Here's the minimal setup:
The Future of Enterprise AI-Data Integration#
pxt.retrieval_udf() represents a fundamental shift in how AI systems interact with enterprise data. Instead of forcing structured data into unstructured formats or building complex API layers, we're giving AI models native access to the databases they need to query.
This approach aligns with Pixeltable's vision of declarative AI infrastructure, where data access becomes as simple and powerful as SQL was for traditional applications.
This Opens Up Possibilities For:#
- Hybrid RAG systems combining semantic search with precise database queries
- Agentic workflows that can access any enterprise system transparently
- Real-time AI applications that work with live, changing operational data
- Precise enterprise retrieval without semantic search approximations when exactness matters
- Multi-modal AI systems that query both unstructured content and structured records
Frequently Asked Questions About AI Database Integration#
What is pxt.retrieval_udf() and how does it work?
pxt.retrieval_udf() is a Pixeltable function that converts any database table into an AI-queryable tool. It creates a bridge between LLMs and structured data, allowing AI agents to query databases using natural language while maintaining the performance and security of native database operations.
How is this different from traditional RAG systems?
Traditional RAG systems use vector embeddings for semantic search over unstructured documents. retrieval_udf() enables direct, precise queries over structured data like customer records, product catalogs, and financial data. You can combine both approaches for powerful hybrid AI systems.
Is it secure for enterprise data access?
Yes! You control exactly which columns AI agents can query through the parameters argument. All queries are parameterized to prevent SQL injection. The tool only accesses data through the specific parameters you define, ensuring enterprise-grade security.
Which LLM providers work with retrieval_udf()?
All major LLM providers work with retrieval_udf(), including OpenAI, Anthropic's Claude, Google's Gemini, Together AI, and local models. The tool integration follows OpenAI's function calling standard, making it universally compatible.
How does performance compare to custom APIs?
Performance is often superior because retrieval_udf() uses Pixeltable's optimized query engine with native SQL operations, intelligent caching, and efficient result limits. There's no overhead from embedding computation, and queries benefit from database indexes and optimizations.
Can I combine multiple database tables in one AI agent?
Absolutely! You can create multiple retrieval_udf() tools from different tables and register them all with pxt.tools(). The AI agent will automatically choose the appropriate tool based on the user's query, enabling access to your entire enterprise data ecosystem.
