How Khoj Works: Architecture and Technical Details

Khoj is built on a modular architecture that separates concerns between the core engine, model integrations, and user-facing interfaces. Here's an overview of how the system operates:

Core Engine: The heart of Khoj processes requests, manages state, and orchestrates interactions between different components. Built with Python, it prioritizes performance and reliability while maintaining clean, maintainable code.

Model Integration Layer: Khoj connects to various AI model providers through a unified interface. This abstraction layer means you can switch between different LLMs (OpenAI, Anthropic, local models, etc.) without changing your application logic.

Task Processing Pipeline: When a task is submitted, Khoj breaks it down into manageable steps, processes each step through the appropriate components, and aggregates results. This pipeline approach ensures consistent, reliable output even for complex multi-step operations.

Storage and State Management: Khoj maintains conversation history, configuration state, and cached results using efficient storage mechanisms. This enables context-aware processing and faster response times for repeated operations.

API and Interface Layer: External applications interact with Khoj through well-documented APIs and interfaces, making integration straightforward for developers building on top of the platform.
