# Yukun Huang, Sanxing Chen, Jian Pei, Manzil Zaheer, and Bhuwan Dhingra describe the method in their paper .

## Retrieval answer

**Thesis:** CitePretrain shifts citation attribution work from answer-time retrieval into continual pretraining, but its citations are bounded by the documents indexed during training.

**Thesis:** CitePretrain shifts citation attribution work from answer-time retrieval into continual pretraining, but its citations are bounded by the documents indexed during training.

**Observed facts:** The paper introduces CitePretrainBench with Wikipedia, Common Crawl, arXiv, and novel unseen documents, spanning short- and long-form citation tasks. On Qwen-2.5-7B and 3B, Active Indexing improved citation precision over Passive Indexing on every evaluated task, with gains up to 30.2 percentage points.

**Mechanism:** Continual pretraining binds facts to persistent document identifiers; instruction tuning teaches the model to emit identifiers as citations. Active Indexing adds synthetic source-to-fact and fact-to-source examples. Continual pretraining binds facts to persistent document identifiers; instruction tuning teaches the model to emit identifiers as citations. Active Indexing adds synthetic source-to-fact and fact-to-source examples.

**Why now:** The paper tests whether internalized source associations can complement or sometimes substitute for external retrieval when traceability is sought without a retrieval call per answer.

**First implication:** The first implication is that internal citations may offer a lower-latency fallback when retrieval is unavailable, while remaining limited to the indexed training corpus.

**Evidence boundary:** The evidence boundary is the authors’ benchmark and experiments on Qwen-2.5-7B and 3B; the reported gains do not establish reliable provenance for arbitrary answers or production use.

**First watch condition:** The first watch condition is whether independent evaluations test citation resolution and attribution errors on models and corpora beyond this benchmark.

A document identifier is only useful as evidence if it can be resolved against a maintained catalog and if the cited document actually supports the claim. The paper therefore describes a route to learned attribution, not a guarantee that citations provide faithful explanations of how a model produced an answer. External retrieval and internal citations can be complementary: one depends on current indexes, the other on what was represented during training.
