The model can interject backchannels while a user speaks and respond before the user finishes. It is positioned as the first full-duplex model besides GPT-Live capable of intelligent Japanese dialogue, and Shizuku AI reports performance second only to GPT-Live-1 among full-duplex models.","whyItMatters":"Shizuku AI is staking its AI VTuber business on conversation pacing rather than raw model scale, and its own benchmark places Shizuku-Duplex behind GPT-Live-1 while well ahead of existing Japanese full-duplex models.","webCardHtml":"\u003cp\u003eShizuku AI built the model for its AI VTuber Shizuku, and a posted conversation example has the persona interjecting short backchannels, answering without a pause after the user stops, and saying \u0026#34;please wait a moment\u0026#34; before a detailed reply. Before audio comes out, Shizuku-Duplex writes the dialogue line as text in an \u0026#34;Inner Monologue\u0026#34; step. Inference optimization with TensorRT and Triton kernels supports the 80-millisecond cycle.\u003c/p\u003e\u003cp\u003eFor questions that need a web search, the model gives a short spoken answer while the search runs, then delivers the detailed answer without breaking the flow. Conversation history is summarized every 5 minutes to keep long sessions stable. Shizuku AI says it will continue work on vision and motion.\u003c/p\u003e","blueskyPost":"Shizuku AI's claim that Shizuku-Duplex ranks second only to GPT-Live-1 among full-duplex models rests on its own benchmark.

The model handles web-search questions by speaking a short answer first, then a detailed one, and summarizes conversation history every 5 minutes for long sessions. Shizuku AI positions it as second only to GPT-Live-1 among full-duplex models in its own performance tests.","attributionJson":"[{\"source\":\"GIGAZINE\",\"url\":\"https://gigazine.net/news/20261109-shizuku-duplex-natural-conversation-ai/\",\"title\":\"Shizuku-Duplex, an AI capable of real-time conversation in Japanese, arrives with high-speed processing every 80 milliseconds, supporting backchanneling and web search\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":5654,"outputTokens":811,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1794197084,"createdAt":"2026-11-09T04:02:02.000Z","publishedAt":"2026-11-09T04:02:25.000Z","updatedAt":"2026-11-09T04:02:25.000Z"},"cluster":{"id":"c_7b4441deeffe587c22ced1b0","canonicalTitle":"日本語でリアルタイム会話可能なAI「Shizuku-Duplex」が登場、80ミリ秒ごとに高速処理して相づちやウェブ検索にも対応","representativeArticleId":"a_97474862daeaf218ab699d72","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"Shizuku-Duplex\"],\"studios\":[\"Shizuku AI\"],\"people\":[],\"type\":\"announcement\",\"domain\":\"vtuber\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-11-09T03:13:00.000Z","lastSeenAt":"2026-11-09T03:13:00.000Z","updatedAt":"2026-11-09T04:02:27.000Z"},"attribution":[{"source":"GIGAZINE","url":"https://gigazine.net/news/20261109-shizuku-duplex-natural-conversation-ai/","title":"日本語でリアルタイム会話可能なAI「Shizuku-Duplex」が登場、80ミリ秒ごとに高速処理して相づちやウェブ検索にも対応"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["Shizuku-Duplex"],"studios":["Shizuku AI"],"people":[],"type":"announcement","domain":"vtuber","is_roundup":false},"keyFacts":["Shizuku AI announced Shizuku-Duplex, a full-duplex model for real-time Japanese voice conversation.","Shizuku-Duplex runs real-time inference every 80 milliseconds.","The model can interject backchannels while the user is speaking and respond before the user finishes.","Shizuku AI positions Shizuku-Duplex as the first full-duplex model besides GPT-Live capable of intelligent Japanese dialogue.","Shizuku-Duplex summarizes conversation history every 5 minutes for stable output in long conversations."],"pageLinks":{"healthSlugs":["shizuku-duplex","shizuku-ai"],"storySlugs":[],"entities":[{"slug":"shizuku-duplex","supported":0,"disputed":0,"contradicted":0,"unverified":5,"overall":"unverified","story_count":1,"has_dossier":false},{"slug":"shizuku-ai","supported":0,"disputed":0,"contradicted":0,"unverified":1,"overall":"unverified","story_count":1,"has_dossier":false}],"stories":[],"entitiesOk":true,"storiesOk":true}}
