Transforming Banking with Advanced AI: GenAI, RAG, and Multi-Agent Systems by Kevin Suys

Ai

Discover how AI transforms banking through RAG and multi-agent systems. Learn implementation strategies, from data quality to evaluation methods, for building robust AI solutions.

Key takeaways
  • RAG (Retrieval Augmented Generation) helps pre-select relevant documents before sending to LLMs, improving accuracy and reducing hallucinations

  • Data quality and chunking strategies are crucial for effective RAG implementation - including naive chunking (word/sentence/paragraph) and more advanced contextual approaches

  • Multilingual embeddings allow for language-agnostic vectorization, enabling responses in different languages while maintaining knowledge base in one language

  • Input and output guardrails help validate queries and responses, preventing harmful content and ensuring high-quality, relevant answers

  • Hybrid retrieval approaches combining traditional keyword search with vector search can improve result relevance

  • Re-ranking retrieved documents helps improve diversity and reduces redundant or too-similar results

  • Multi-agent systems with specialized agents (coding, business knowledge, etc.) can handle complex tasks more effectively than single LLM approaches

  • Regular evaluation of RAG systems should measure precision, recall, answer relevancy and faithfulness to source material

  • Token optimization and context window management are important for cost and performance efficiency

  • Modular architecture allows switching between different models (open/closed source) as technology evolves rapidly
