The model has 1.05 trillion total parameters and 49 billion active parameters in a Mixture-of-Experts setup. It handles text and images, supports a 1-million-token context window and over 160 languages, and is available through the Mistral API, with open weights planned for the end of October, according to Mistral.","whyItMatters":"Mistral is positioning its largest open-weight release directly against Chinese open-weight models, and the company says it is deployable from European infrastructure through its own Mistral Cloud.","webCardHtml":"\u003cp\u003eMistral Large 4 carries 1.05 trillion total parameters but activates 49 billion during inference, a Mixture-of-Experts split that keeps the model\u0026#39;s runtime cost tied to the smaller number. It also pairs that setup with a 1.6-billion-parameter image encoder and a 1-million-token context window, and Mistral says multilingual data covers more than 160 languages, including all official EU languages.\u003c/p\u003e\u003cp\u003eThe company frames the model\u0026#39;s benchmarks against Chinese open-weight competitors in particular. Mistral says its aggregated Coding Agent Index reached 49.8%, above DeepSeek V4 Pro 0813 and Qwen3.8 Max. In a code evaluation run with Surge AI, where professional scorers rated generated code without seeing model names, Mistral Large 4 averaged 3.74 out of 5.\u003c/p\u003e","blueskyPost":"Mistral Large 4's 49 billion active parameters against 1.05 trillion total shows the real bet is routing efficiency: open weights arrive only at month's end, so API access is the interim test of that architecture.","twitterPost":"1.05 trillion total parameters, 49 billion active: Mistral Large 4 bets the architecture, not raw size, will carry it.","threadsPost":"Mistral Large 4 carries 1.05 trillion total parameters but activates only 49 billion, so Le Chonk's performance will be judged on routing rather than raw scale. Open weights arrive at the end of October, which leaves API users as the first test of whether that Mixture-of-Experts design holds up.","newsletterBlurb":"Mistral announced Mistral Large 4 on October 6, a multimodal model with 1.05 trillion total parameters and 49 billion active. The company says its aggregated Coding Agent Index beat DeepSeek V4 Pro 0813 and Qwen3.8 Max, and that open weights follow at the end of October after today's API availability.","attributionJson":"[{\"source\":\"GIGAZINE\",\"url\":\"https://gigazine.net/news/20261007-mistral-large-4-le-chonk/\",\"title\":\"Mistral Announces 'Mistral Large 4 Le Chonk' With Over 1 Trillion Parameters, an Open-Weight AI Model to Rival Chinese Players\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":4741,"outputTokens":665,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1791344228,"createdAt":"2026-10-07T03:31:23.000Z","publishedAt":"2026-10-07T03:36:05.000Z","updatedAt":"2026-10-07T03:36:05.000Z"},"cluster":{"id":"c_be7164d7bd2ed0ef36f4fa6c","canonicalTitle":"1兆パラメータ超の「Mistral Large 4 Le Chonk」をMistralが発表、中国勢に対抗するオープンウェイトAIモデル","representativeArticleId":"a_4a451584fdfb2145ca68ef1e","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"Mistral Large 4\"],\"studios\":[\"Mistral\"],\"people\":[],\"type\":\"announcement\",\"domain\":\"other\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-10-07T02:15:00.000Z","lastSeenAt":"2026-10-07T02:15:00.000Z","updatedAt":"2026-10-07T03:36:06.000Z"},"attribution":[{"source":"GIGAZINE","url":"https://gigazine.net/news/20261007-mistral-large-4-le-chonk/","title":"1兆パラメータ超の「Mistral Large 4 Le Chonk」をMistralが発表、中国勢に対抗するオープンウェイトAIモデル"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["Mistral Large 4"],"studios":["Mistral"],"people":[],"type":"announcement","domain":"other","is_roundup":false},"keyFacts":null}
