Which open-weight interactive or action-conditioned world models were released after Oasis and DIAMOND (Matrix-Game 1.0-4.0, Hunyuan-GameCraft, LingBot-World 1 and 2), what is actually released for each, and what licence is attached to which part?

Eight released model lines with public weights were found: Matrix-Game 1.0 (MIT), 2.0 (MIT), 3.0 (Apache-2.0, 5B base and distilled; a 28B model is announced as 'soon'), 4.0 (Apache-2.0; scene checkpoints for three games, released 2026-10-15), Hunyuan-GameCraft-1.0 (Tencent Hunyuan Community License with territory exclusions), LingBot-World 1 (Apache-2.0) and LingBot-World 2.0/Infinity (CC BY-NC-SA 4.0, non-commercial). Licences differ by version inside one project and by component (code, weights, game assets, bundled third-party models). 'Open weights' here means files present on Hugging Face at the pinned revision with a licence text; nothing was downloaded or run. Curator correction 2026-10-24 (discovery audit record C3-B1075-01, curator-reviewed C3R-0688; excerpts re-located by independent curator GET 2026-10-24): Correction. C3-B019-W6-05's summary opens 'Eight released model lines with public weights were found'. Its own systems list has eight entries, but one of them, Matrix-Game 3.0 28B MoE, is not released: the record itself marks it 'none at the pinned revision (README: will be released soon)' and its finding F4 says 'Announced is not released'. Released lines in the record are seven: Matrix-Game 1.0, 2.0, 3.0 (5B base and distilled), 4.0, Hunyuan-GameCraft-1.0, LingBot-World 1 and LingBot-World 2.0/Infinity. The wrong count was in the record from the start (it was not a later change). Re-fetched 2026-10-24: the Matrix-Game-3 README on the main branch still says the 28B model 'will be released soon', and the Skywork Hugging Face model listing shows Matrix-Game, 2.0, 3.0, 4.0 and Matrix-3D but no 28B repository. The licences in the record (MIT for Matrix-Game 1.0/2.0, Apache-2.0 for 3.0/4.0, CC BY-NC-SA 4.0 for LingBot-World 2.0) were re-checked against Hugging Face model metadata and the LingBot-World 2.0 README badge on 2026-10-24 and still match. Curator qualifications: HF API licence tags (fetched 2026-10-22): Matrix-Game mit (sha 6de12811), Matrix-Game-2.0 mit (08c42d1a), Matrix-Game-3.0 apache-2.0 (382aa382), Matrix-Game-4.0 apache-2.0 (2c531004, equal to the producer's card revision prefix), Hunyuan-GameCraft-1.0 no licence tag (022caa86; licence via LICENSE file, see C3R-0026), lingbot-world-v2-14b-causal-fast cc-by-nc-sa-4.0 (5c33dd40). Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [component_reuse_restriction] LingBot-World 1 licence not re-checked by curator. [component_reuse_restriction] HF tags are not licence text; NOTICE/third-party components per W6-08 remain open. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
