Why HN links it

HN readers link this blog's deterministic-quoting post as an example of getting LLMs to cite exact strings from a source document, a pattern commenters connect to RAG citations and Anthropic's API citations feature.

What Hacker News says?

  1. You may be interested "Deterministic Quoting"[1]. This doesn't completely "solve" hallucinations, but I would argue that we do get "good enough" in several applications Disclosure: author on [1] [1] https://mattyyeung.github.io/deterministic-quoting

  3. I don't see how a RAG that can cite sources from a document doesn't addresses this already (example [1])? Although I admit it's not a perfect solution yet... [1] https://mattyyeung.github.io/deterministic-quoting

  5. Yeah, I think they fine-tuned their model to be better at the pattern where you output citations that reference exact strings from the input. Previously that's been a prompting trick, e.g. here: https://mattyyeung.github.io/deterministic-quoting
