LLMs can now cite their sources

My latest post on The New Stack reveals how researchers pinpoint the exact sources behind chatbot responses.


Today the Allen Institute for Artificial Intelligence (Ai2) unveiled OLMoTrace — a seemingly minor feature with major implications for AI verifiability.


Check out my post on The New Stack, which dives into the technology that is allowing LLMs to cite the exact source behind chatbot responses.


I was excited to see this since LLMs have struggled with transparency. I sense this could set a precedent for other chatbots to embed similar traceability.
