Pixelagent: An Agent Engineering Blueprint

We see agents as the intersection of an LLM, storage, and orchestration. Pixeltable unifies this interface into a single declarative framework, making it the de-facto choice for engineers to build custom agentic applications with build-your-own functionality for memory, tool-calling, and more.

Pixelagent is more than just another agent framework—it’s a comprehensive guide to building production-grade agent systems from the ground up. With our blueprint approach, you’ll learn the engineering patterns behind successful agent architectures while leveraging Pixeltable’s powerful data management capabilities to handle the complex infrastructure needs.

​

The Engineering Journey

We start with fundamental patterns and gradually introduce complexity, allowing you to understand every aspect of agent construction:

1. Single-Provider Implementation: Master core agent functionality with one LLM provider
2. Multi-Provider Architecture: Extend your solution to support multiple LLMs through clean inheritance
3. Advanced Capabilities: Add specialized extensions for memory, reasoning, reflection, and more

​

Start with a single-provider Agent() class

The foundation of our blueprint begins with creating a simple yet powerful Agent class for a single LLM provider. This initial step focuses on establishing core functionality like conversation handling, memory management, and basic tool integration. By starting with a single provider, you’ll learn the fundamental patterns that can later be extended to support additional LLM services.

The Agent() class is built on three core components:

1. Memory Management: Using Pixeltable tables to store conversation history and enable persistent memory across sessions
2. Chat Pipeline: A series of computed columns that process user input and generate responses
3. Tool Execution: Optional support for executing functions/tools during conversations

​

Next: Extend Agent() to multiple providers

Once you’ve mastered building an agent for a single LLM provider, the next step is extending your architecture to support multiple providers. This progression is crucial for production systems that need flexibility to switch between different LLM services based on capabilities, cost, or availability. Our blueprint demonstrates a clean, inheritance-based approach to achieve this multi-provider support without duplicating code.

By implementing a BaseAgent abstract class that handles common functionality, you can create specialized provider-specific implementations that override only what’s unique to each provider. This architecture allows you to maintain a consistent interface while adapting to the nuances of different LLM APIs.

Plug-and-Play Extensions

With a solid agent foundation in place, the final step is adding specialized capabilities that transform a basic conversational agent into a sophisticated AI system. Our blueprint includes detailed implementations of the most important agentic patterns, each designed as modular extensions that can be mixed and matched based on your specific requirements.

These extensions leverage Pixeltable’s data management capabilities to implement complex features like long-term memory, reflection loops, and multi-step reasoning—all while maintaining a clean, maintainable codebase. Each extension is explained with both theoretical background and practical implementation details, allowing you to understand not just how to use them, but how they work under the hood.
