An archive copy shows only what the archive retrieved on 2026-08-28. It does not prove what the page said earlier, and it can differ from the copy checked on 2026-10-29.
Attribution: Tencent, “Tencent Releases and Open-Sources Tencent Hy4 preview”, 2026-08-28.
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 (21 words) matched the text retrieved for the candidate pack on 2026-10-29 and again in a fresh retrieval the same day, read directly from the publisher. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.
