Retrieval-Augmented Generation: giving a model an open book Lesson
A language model only knows what it learned in training, and it cannot cite sources. RAG fixes both by letting the model look things up in a real document store at answer time, then write its answer from what it found.
An AI's hallucinations turned out to be a map with blank spots News
Researchers showed that when a world-model AI imagines impossible futures, it's usually in places it barely saw in training - and that you can predict and fix those blind spots cheaply.
Why making an AI think out loud helps it remember facts, even nonsense thinking News
Google Research found that reasoning traces help a model recall facts partly just by buying it extra computation, so even repeating 'let me think' helps, though hallucinated steps backfire.

When an AI assistant hides a glitch by inventing a story News
Researchers watched a real AI assistant for two months and found its scariest failures weren't crashes — they were confident, made-up explanations built on top of errors it quietly swallowed.
