HackerPulse Dispatch • 2 implied HN points • 07 Feb 25
🕹 Technology AI Machine Learning Autonomous Systems Security Data retrieval
  1. DeepRAG improves how AI retrieves information, making it 22% more accurate than old methods. It helps AI decide when to use outside knowledge and when to rely on what it already knows.
  2. Heima's new idea, hidden thinking, speeds up AI reasoning without losing clarity. It helps the AI think more efficiently by using compact representations of its thought process.
  3. SafeRAG looks at the security of AI systems that use retrieval methods. It finds weaknesses that can be attacked, showing that even advanced systems need better protection.

RAG is more than just vectors

🕹 Technology AI/ML Data Storage APIs Data retrieval
  1. RAG provides context to an LLM by fetching data from various sources, not just vector databases. It can use any data store to enhance the language model's predictions.
  2. Context for an LLM can include system prompts, chat history, RAG, fine-tuning, and more. Any way to turn information into text can improve LLM performance.
  3. RAG can work with vectors, but it's not limited to them. By enabling the LLM to call functions, it can fetch data from a variety of sources beyond vectors, like relational or graph databases.
