Attribution: Shitao Xiao, Zheng Liu, Peitian Zhang, Niklas Muennighoff, “C-Pack: Packaged Resources To Advance General Chinese Embedding”, 2023-09-14.
Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, Chinese frontier-AI institutions, third collection (research/china-labs-3). The quotation (2 words) was matched at admission on 2026-10-31 in a direct retrieval whose SHA-256 equals the pack’s. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. The pack had joined the author and the affiliation into one quotation across intervening authors; at admission each became its own quotation (cross-family check, item K033). A cross-family machine check (2026-10-31, item K033) answered the record’s question blind from fresh retrievals and agreed in part; the admission record lists how each point was handled. No human editorial review.
