The official version of the Hy4 preview builds on a Mixture of Experts architecture with 770 billion total parameters and 49 billion used during inference, a roughly 1 million token context window, and image understanding for the first time in the Hy series.","whyItMatters":"By scheduling an open weight release for a model it compares against DeepSeek and Kimi, Tencent is competing for the open model position rather than keeping Hy4 behind a closed API.","webCardHtml":"\u003cp\u003eTencent\u0026#39;s own evaluation used WorkBuddy, its work support tool, where Hy4 averaged 83.18 points and a 96.15% task success rate. In a financial blind test run with 213 experts across 579 tasks, Hy4 scored 3.04 against 2.97 for DeepSeek-V4.1-Flash-1017 and 2.68 for Kimi K3.1 Pro and GLM-5.3. Tencent also trained the model on Blender and CAD software and on Unreal Engine, Unity, and Godot for game development.\u003c/p\u003e","blueskyPost":"Tencent's Hy4 uses 49 billion of 770 billion parameters at inference. The open weights promise matters less than what a sparse MoE that size costs to run.","twitterPost":"Hy4 runs 49 billion of its 770 billion parameters per query, so open weights still leave the compute bill with whoever hosts it.","threadsPost":"Tencent's Hy4 runs on 49 billion of 770 billion parameters per query, and the million-token context plus image understanding add load. Publishing weights lowers the entry cost but not the hardware floor.","newsletterBlurb":"Tencent announced Hy4 on November 4, 2026, the official version of the Hy4 preview announced in August. The company says it will release the model weights in the near future. Tencent's own evaluations place it ahead of DeepSeek-V4.1-Flash-1017 and Kimi K3.1 Pro on a financial blind test.","attributionJson":"[{\"source\":\"GIGAZINE\",\"url\":\"https://gigazine.net/news/20261105-tencent-hy4/\",\"title\":\"China's Tencent Announces High-Performance AI Model \\\"Hy4,\\\" Promises to Release It as an Open Model\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":5569,"outputTokens":744,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1793852397,"createdAt":"2026-11-05T04:16:42.000Z","publishedAt":"2026-11-05T04:18:53.000Z","updatedAt":"2026-11-05T04:18:53.000Z"},"cluster":{"id":"c_0ee2c6f08f9372cbb2282903","canonicalTitle":"中国・Tencentが高性能AIモデル「Hy4」を発表、オープンモデルとして公開することを約束","representativeArticleId":"a_77ac52e7932a7e30a53028d3","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"Tencent Hy4\"],\"studios\":[\"Tencent\"],\"people\":[],\"type\":\"announcement\",\"domain\":\"industry\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-11-05T03:29:00.000Z","lastSeenAt":"2026-11-05T03:29:00.000Z","updatedAt":"2026-11-05T04:18:53.000Z"},"attribution":[{"source":"GIGAZINE","url":"https://gigazine.net/news/20261105-tencent-hy4/","title":"中国・Tencentが高性能AIモデル「Hy4」を発表、オープンモデルとして公開することを約束"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["Tencent Hy4"],"studios":["Tencent"],"people":[],"type":"announcement","domain":"industry","is_roundup":false},"keyFacts":["Tencent announced the Hy4 AI model on November 4, 2026.","Hy4 is the official version of the Hy4 preview announced in August 2026.","Hy4 has 770 billion total parameters and 49 billion used during inference.","Tencent says it will release the model weights in the near future.","In Tencent's financial blind test, Hy4 scored 3.04 against 2.97 for DeepSeek-V4.1-Flash-1017 and 2.68 for Kimi K3.1 Pro and GLM-5.3."],"pageLinks":{"healthSlugs":["tencent-hy4","tencent"],"storySlugs":[],"entities":[{"slug":"tencent-hy4","supported":0,"disputed":0,"contradicted":0,"unverified":3,"overall":"unverified","story_count":1,"has_dossier":false},{"slug":"tencent","supported":0,"disputed":0,"contradicted":0,"unverified":17,"overall":"unverified","story_count":11,"has_dossier":true}],"stories":[],"entitiesOk":true,"storiesOk":true}}
