Grok Voice Transcribe 2.0 has officially launched The new speech-to-text model is around 2× more accurate than Transcribe 1.0 across its real-world evaluations.....at exactly the same price And it is already ranking #1 for accuracy among 32 streaming transcription models on Artificial Analysis But the bigger upgrade is how well it handles messy real-world audio Grok Voice Transcribe 2.0 was built for: • Noisy phone calls • Multiple people speaking • Local accents • Phone numbers, emails and addresses spoken aloud • Short voice commands • Multilingual conversations • People switching languages in the middle of the same recording On SpaceXAI’s multilingual short-phrase test, word error rate dropped from 20.6% → 6.8%....insanely low And it comes with a pretty serious feature set: • Real-time streaming + batch transcription • Automatic language detection • Mid-conversation language switching • Word-level timestamps + confidence scores • Speaker diarization at no extra cost • Up to 8 audio channels • Biasi

SpaceXAI is testing Remote Control for Grok Build This is one of the biggest Grok Build updates yet....and the one future I was desperately waiting for Grok Build... it's finally coming You’ll be able to link your computer once through the Grok Build CLI, then control Grok Build remotely from the web and directly from the Grok app on your phone That means Grok Build can keep working on your actual computer while you’re somewhere else with nothing but your phone

Grok Bot is getting much more deeply embedded into XChat At this point it’s pretty obvious where this is going You’ll be able to chat with Grok Bot directly from XChat You’ll also be able to link your Grok account with 𝕏 and access your own Grok Bots right inside XChat So no more jumping between apps....your bots will basically live alongside your conversations on 𝕏

@blankspeaker

SpaceXAI: We are getting closer to X allowing you to link your Grok account to X and being able to view your Grok Bots right in XChat. > They seem to be refining the UI still on Web and Android but I think it will ship really soon.

New model leak: grok-voice-transcribe-2.0 Maker: xAI Detected via Grok web app bundle models.

SpaceXAI should skip Grok 4.7 and put everything on 4.8... Since Grok 4.7 is a patch on the old RL that's why it quits early...that’s why multimodal is still broken.. that’s why they keep delaying it... while 4.8 is the actual upgrade with 2.5T parameters plus new C++ stack from the Starlink team... shipping a mid model just to hit a tweeted date wastes the week that's why they should skip the patch and ship the stack instead..

Use Grok Voice in fal to build intelligent, low-latency agents that resolve real customer issues

@fal

Grok Voice is live on fal. > The latest speech model from @SpaceXAI that answers in 0.70 seconds and finishes its tool calls before the sentence ends. Transcription with word-level timestamps, text to speech in 30+ voices across 25+ languages, and cloning from two minutes of audio. > Every voice in this video is from Grok Voice.

🚨 Grok 4.7 better not be fucking mid today. 👀 August: “It’ll beat every model out there.” September: “Roughly on par with Opus 5.0, not 5.2” And the Astra/Fable-class model? Apparently that’s Grok 4.9 😭 Bro went from “best model in the world” → “wait for 4.9” After all that hype and all those delays… What the fuck did xAI actually cook? 👀🔥

ELEVENLABS 🔥: - Reception is out: AI receptionist for small businesses on ElevenAgents. Add

SpaceXAI is working on Team Bots for Grok Bot Teammates can be able share Bots with each other, and you can add useful shared Bots directly to your sidebar So instead of everyone building the same agents separately, teams can work from the same Bots Looks like this is being built for Team and Enterprise accounts

SpaceXAI is working on Team Bots for Grok Bot. > Open Team bots to see agents your teammates shared, then add one to keep it in your sidebar so everyone on the team can work from the same bots. > This likely is being built and coming soon for Team and Enterprise accounts.

Everyone was expecting Grok 4.7 around September 12 We're now on September 16 and it's still nowhere to be seen 👀 Musk says it needs more time to fix its reasoning and self checking At this point, I just want to see what xAI has been cooking

我去，这也太牛了！ 估计只有老马敢这么干啊~ 三个人，72 小时，从零开始造一家公司。 没有名字，没有产品，没有想法。 唯一的员工就是是 Grok Bot。 SpaceXAI 正在做一件大多数 AI 公司不敢做的事：把自家 Agent 扔进一场完全公开的 72 小时直播压力测试。 9 月 15 日到 17 日，Matt Palmer、Lauren Tan 和 Roshan Sadanani 在旧金山 The Howard 现场直播，用 Grok Bot 跑完从构思、商业计划、产品决策到工程开发和部署的全链路。 每天早 8:30 到晚 6:00 PT，全球免费观看。 连续三个工作日、连续直播、所有失败都被摄像头拍到的真实建造过程。 日程是这样安排的哈： 第一天是 Grok Bot 101、工程和产品管理。 第二天进入商业流程：售前、销售、SDR、客服。 第三天是营销运营和最终展示。 Lauren Tan 同时是 React Core Team 成员，参与构建 React Compiler。 Matt Palmer 这样说：「我们会用 Grok Bot 做每一个环节，从构思和产品开发到真正的工程和部署。」 如果失败了，他们要被罚吃披萨。 这也太牛逼了，简直是疯狂啊，老马的基因里给企业的员工都带来的巨大的影响，就喜欢挑战哈哈 不是因为三个人要在三天里造一家公司而牛逼。 牛的事他们 SpaceXAI 愿意把这件事的每一秒都播给你看。 大多数 AI 公司给你一段精心剪辑过的 demo。 这三个人给你 30 个小时的未剪素材。 你自己判断 Agent 到底能不能干活。

🚨 GROK 5 LEAKS: Elon Just Admitted Something He Never Said Before >Training reportedly continues after Grok 4.8, landing in October >Grok 5 rumored at ~6T parameters >Elon: "I now think xAI has a chance of reaching AGI with Grok 5 never thought that before" Puts the odds at 10%, "and rising" >Expected to challenge GPT-6 Astra and Fable 5.1 Reportedly cheaper to run than rivals If Elon's own confidence is climbing, how close is Grok 5 actually getting

SpaceXAI just announced a 3-day livestream to build a company from scratch using Grok Bot. Here's what you need to know. Elon Musk shared the announcement today, promoting "Grok Bot Galaxy," a live event where three people start with just an idea and try to build an entire product or company from nothing, using Grok Bot as their AI teammate. The livestream runs September 15 to 17, roughly 8:30 AM to 6:00 PM PT each day, streamed from The Howard at 661 Howard St in San Francisco. Day one opens with a Grok Bot 101 session, followed by a Grok Bot for Engineering session. The company name has not been chosen yet. This builds on Grok Bot, xAI's AI agent that launched in beta on August 11. Each Bot gets its own persistent cloud computer, with a desktop, files, terminal, browser, and apps, and can keep working around the clock without supervision. Key numbers: - Livestream dates: September 15 to 17, 2026 - Daily hours: about 8:30 AM to 6:00 PM PT - 3 builders, 1 company, built from scratch - Grok Bot beta launch

Try Grok Build

@XFreeze

I literally use Grok Build to edit images and videos....not just generate them, which it can also do > I mean actual image and video editing....the kind of stuff you would normally sit in Photoshop or editing software and do manually > I can tell Grok Build what I want changed, have it find the right footage, cut clips, edit everything together and handle a lot of the repetitive work for me > You can even save your preferred designs and workflows as skills....so it knows exactly how you like things done every time > It saves me an insane amount of time

Elon Musk just gave a huge update on Grok 4.8 Grok 4.8 is a massive 2.5T model trained using SpaceXAI’s new C++ software stack Pretraining finishes this week.....then it moves straight into reinforcement learning While Grok 4.7 is getting its final refinements.....and Grok 4.8 is already moving into its next phase

Elon just gave a huge update on the Grok model roadmap and Grok 4.8 is the major step forward • Grok 4.7 — roughly on par with Opus 5.0, better in some areas and worse in others....multimodal performance still needs work • Grok 4.8 — a massive 2.5T model trained on SpaceXAI’s new C++ software stack....training finishes this week and then moves straight into reinforcement learning • Grok 4.9 — Astra/Fable class • Grok 5 — potentially better than anything The crazy part is 4.7 hasn’t even launched yet and 4.8 is already finishing training Then 4.9 and Grok 5 are lined up right behind it Elon is moving the entire Grok roadmap insanely fast

@elonmusk

@itslueul Grok 4.7 should be roughly on par with Opus 5.0, not 5.1. Better in some ways, worse in others. We need to fix multimodal performance. > Grok 4.8 will be a noticeable improvement. > Grok 4.9 is probably Astra/Fable class. > Grok 5 maybe better than anything. We shall see.
