Key Concepts​

RAG (Retrieval-Augmented Generation)​

RecoAgent uses RAG to combine the power of large language models with your private knowledge base. This approach:

  • Retrieves relevant documents from your knowledge base
  • Augments the LLM's context with retrieved information
  • Generates accurate, grounded responses

Hybrid Retrieval​

We combine multiple search strategies:

  • Vector Search - Semantic similarity using embeddings
  • Keyword Search - BM25 for exact term matching
  • Reciprocal Rank Fusion - Combines results intelligently

Agent Orchestration​

LangGraph powers our agent workflows:

  • State Management - Tracks conversation context
  • Tool Integration - Connects to external services
  • Error Handling - Graceful failure recovery
  • Multi-step Reasoning - Complex problem solving

Design Philosophy​

Production-First​

RecoAgent is designed for enterprise use:

  • Scalability - Handle thousands of concurrent users
  • Reliability - 99.9% uptime with graceful degradation
  • Security - Built-in safety guardrails and PII protection
  • Observability - Comprehensive monitoring and tracing

Developer Experience​

We prioritize ease of use:

  • Simple Setup - Get running in minutes
  • Clear APIs - Intuitive interfaces and documentation
  • Rich Examples - Working code for common scenarios
  • Comprehensive Testing - Automated validation and CI/CD

Quality Assurance​

Quality is built into every layer:

  • Evaluation Metrics - RAGAS-based performance measurement
  • Automated Testing - Continuous validation of examples
  • Code Quality - Linting, formatting, and best practices
  • Documentation - Living docs that stay current

Trade-offs and Decisions​

Accuracy vs. Speed​

  • Hybrid Retrieval - More accurate but slightly slower than pure vector search
  • Cross-encoder Reranking - Higher quality results with additional latency
  • Caching - Faster responses with potential staleness

Flexibility vs. Simplicity​

  • Configurable Components - More options but more complexity
  • Sensible Defaults - Easy to start, possible to customize
  • Plugin Architecture - Extensible but requires more understanding

Cost vs. Quality​

  • Model Selection - Balance between cost and capability
  • Caching Strategies - Reduce API calls while maintaining freshness
  • Evaluation Frequency - Measure quality without excessive cost

Current Limitations​

Performance​

  • Latency - Multi-step reasoning can be slower than simple Q&A
  • Memory Usage - Large knowledge bases require significant RAM
  • API Limits - Subject to LLM provider rate limits

Functionality​

  • File Formats - Limited to text-based documents currently
  • Real-time Updates - Knowledge base updates require re-indexing
  • Multi-language - Primary support for English content

Scalability​

  • Single Instance - Current architecture supports single deployments
  • Database Limits - Vector store capacity constraints
  • Network Latency - Geographic distribution not yet supported

Future Improvements​

Short Term (Next 3 months)​

  • Additional File Formats - PDF, Word, PowerPoint support
  • Real-time Indexing - Live knowledge base updates
  • Performance Optimization - Faster retrieval and generation

Medium Term (3-6 months)​

  • Multi-language Support - Internationalization and localization
  • Advanced Analytics - Usage patterns and insights
  • Enhanced Security - Additional guardrails and compliance features

Long Term (6+ months)​

  • Distributed Architecture - Multi-region deployment
  • Advanced AI Features - Multi-modal capabilities
  • Enterprise Integrations - SSO, LDAP, and enterprise tools
