Mike Del Balso explores how modern RAG architectures enable AI personalization at scale, covering implementation challenges, key success factors & emerging context platforms.

Key takeaways
  • AI-driven personalization is expected to unlock $5 trillion in GDP by 2030 through step-function improvements, not incremental changes

  • Effective AI personalization requires rich context about users, which includes:

    • Profile data from data warehouses
    • Historical behavior and preferences
    • Real-time streaming data from current sessions
    • External API data (weather, events, etc.)
  • Building context systems is a major data engineering challenge:

    • Requires complex data pipelines
    • Real-time data retrieval and joining
    • Large engineering teams at big tech companies
    • Expensive and time-consuming to implement
  • Four levels of context personalization:

    • Zero context (generic recommendations)
    • Batch context (historical data)
    • Real-time context (current user state)
    • Memory/feedback (iterative learning)
  • Context platforms are emerging as a new layer in the AI stack:

    • Handle data retrieval and assembly
    • Manage real-time and historical data
    • Enable personalization without massive engineering teams
    • Keep implementation complexity manageable as systems scale
  • Success factors for personalized AI systems:

    • Must feel like recommendations from a knowledgeable friend
    • Requires both historical and real-time data integration
    • Need explanations for recommendations
    • Should allow user feedback and iteration
    • Must be cost-effective to implement and maintain
