In Artificial Analysis tests, each metric improved over Grok Voice 2.0 and surpassed GPT-Live-1 (Astra, medium) and Gemini 3.8 Live (Ext. Thinking, High). On the Speech to Speech Index it ranked first at 86.9. Input audio costs $4.80 per hour, the same as version 2.0, and the Voice Agent API costs $0.08 per minute.","whyItMatters":"The pricing and latency claims matter because SpaceXAI says Grok Voice 3.0 costs the same as the model it replaces, so existing grok-voice-latest agents switch over without code changes.","webCardHtml":"\u003cp\u003eGrok Voice 3.0 is already running inside Tesla vehicles and at Starlink call centers, and it reached the Voice Agent API on the same day it was announced. SpaceXAI says the model set a record in resolution time for customer support calls. On Big Bench Audio, the average time to first audio was 0.81 seconds, against 1.34 seconds for GPT-Live-1 (Astra, medium) and 1.35 seconds for Gemini 3.8 Live Extended Thinking (High). Cost per hour of input audio is unchanged from Grok Voice 2.0.\u003c/p\u003e","blueskyPost":"Grok Voice 3.0 holds input audio at $4.80 per hour, unchanged from version 2.0, while the Voice Agent API runs $0.08 per minute. Benchmark jumps that don't raise the unit price are the harder sell to developers.","twitterPost":"Grok Voice 3.0 kept input audio at $4.80 per hour while beating the Speech to Speech Index at 86.9. Better numbers, same unit price.","threadsPost":"Grok Voice 3.0 ranked first on the Speech to Speech Index at 86.9, and SpaceXAI left input audio at $4.80 per hour, same as version 2.0. Voice Agent API pricing is $0.08 per minute. The metric gains didn't come with a price cut, which is what enterprise buyers actually weigh.","newsletterBlurb":"SpaceXAI announced Grok Voice 3.0 on October 14, 2026, claiming the title of the world's most intelligent voice-to-voice model on the strength of Artificial Analysis tests. Grok Voice 3.0 ranked first on the Speech to Speech Index at 86.9 and logged 0.81 seconds to first audio on Big Bench Audio. Pricing is unchanged from the previous model, so agents on grok-voice-latest switch over automatically.","attributionJson":"[{\"source\":\"GIGAZINE\",\"url\":\"https://gigazine.net/news/20261015-grok-voice-3/\",\"title\":\"Voice Dialogue AI \\\"Grok Voice 3.0\\\" Launches, Tops Benchmarks with Performance Exceeding OpenAI and Google Models\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":4738,"outputTokens":688,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1792039034,"createdAt":"2026-10-15T04:31:49.000Z","publishedAt":"2026-10-15T04:36:06.000Z","updatedAt":"2026-10-15T04:36:06.000Z"},"cluster":{"id":"c_16cadcea294d7de13e50d004","canonicalTitle":"音声対話AI「Grok Voice 3.0」が登場、OpenAIやGoogleのモデルを上回る性能でベンチマーク首位に","representativeArticleId":"a_9f683cd0526b6bd7936780a4","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"Grok Voice 3.0\"],\"studios\":[\"SpaceXAI\"],\"people\":[],\"type\":\"announcement\",\"domain\":\"other\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-10-15T02:52:00.000Z","lastSeenAt":"2026-10-15T02:52:00.000Z","updatedAt":"2026-10-15T04:36:06.000Z"},"attribution":[{"source":"GIGAZINE","url":"https://gigazine.net/news/20261015-grok-voice-3/","title":"音声対話AI「Grok Voice 3.0」が登場、OpenAIやGoogleのモデルを上回る性能でベンチマーク首位に"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["Grok Voice 3.0"],"studios":["SpaceXAI"],"people":[],"type":"announcement","domain":"other","is_roundup":false},"keyFacts":null}
