Tenet is post-trained on Kimi K2, an open-weight model from the Chinese startup Moonshot, rather than built from scratch. It replaces OpenAI's models inside Harvey's own product, even though OpenAI is one of Harvey's backers. That makes Tenet less a research showcase and more a supply-chain move.\n\nEvery AI-native startup eventually confronts the same math: margins shrink when your core product runs on someone else's metered API. Post-training an open-weight base instead of training a foundation model from scratch is the cheaper, faster path to that independence. It also means a company partly funded by OpenAI is now building tech to replace OpenAI's models in its own flagship product - an awkward but increasingly common tension in the AI industry.\n\nHarvey hasn't published benchmarks showing Tenet beats the OpenAI models it's replacing, so for now this looks like a cost and control story first, a quality story second.","[\"legal-tech\",\"openai\",\"moonshot\",\"kimi-k2\"]","2026-08-23T09:25:58.000Z","2026-08-23T10:14:10.909Z","2026-08-23T10:14:22.834Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Moonshot's released open-weight model is Kimi K2, not 'Kimi K3' — verify and correct the model version before publishing, since citing a nonexistent model version is a checkable factual error even though it originated in the source material.","resolved","ai",[32,33,34,35],"legal-tech","openai","moonshot","kimi-k2",[37],{"name":38,"url":39},"The Next Web","https:\u002F\u002Fthenextweb.com\u002Fnews\u002Fharvey-tenet-legal-model-kimi-k3-chinese-base",0,{"sections":42},[43,46,51,56,61,66,71,76,81,86,91,96,101,106],{"name":44,"slug":30,"count":45,"latest_published_at":18},"AI",3305,{"name":47,"slug":48,"count":49,"latest_published_at":50},"Security","security",455,"2026-08-23T11:00:00.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",216,"2026-08-23T10:30:00.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",145,"2026-08-22T21:25:33.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",91,"2026-08-20T10:01:48.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Startups","startups",50,"2026-08-22T16:23:09.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":107,"slug":108,"count":109,"latest_published_at":110},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
