AIxAI has made Transcribe 2.0 available today in the Grok Voice API. Pricing is $0.10 per hour for batch transcription and $0.20 per hour for streaming. The linked blog post contains further details.

AIxAI released Grok Voice Transcribe 2.0, a speech-to-text model that is twice as accurate as Grok Voice Transcribe 1.0 at the same price, and ranks first for accuracy among 32 streaming models on the Artificial Analysis leaderboard. Batch transcription costs $0.10 per hour of audio and streaming $0.20 per hour, with diarization, timestamps, and key terms included. Existing Speech-to-Text API integrations gain the improvement with no code changes, and developers must pin grok-voice-transcribe-1.0 to stay on the older model during the transition.

AIGrok Voice is now live on fal, and the post says it answers in 0.70 seconds and can finish tool calls before a sentence ends. Its listed capabilities include transcription with word-level timestamps, text to speech in 30+ voices across 25+ languages, and voice cloning from two minutes of audio.

AIGrok Build now has memory, which records conventions, decisions, and project facts after each completed turn and reads them in later sessions. Notes are stored per project plus a global set, and the /dream command organizes them into topic files while /memory opens a read-only browser. The feature is available now and applies to new sessions.

AIMicrosoft is adding Grok models from SpaceXAI to Copilot in Word, Excel, and PowerPoint. The rollout starts with a focused release to customers in the Microsoft Frontier program.

AIGranola says users can bring their meetings into Grok Bot, which is now more powerful for sales teams. The quoted post says Grok Bots can connect to Salesforce, HubSpot, Gong, Clay, Granola, and other GTM tools to track accounts, complete follow-ups, and conduct deep research.

AIxAI built a Grok-powered procurement agent, Haggle Bot, that audits vendor spend, flags unused SaaS seats, and prepares renewal negotiations. The Bot has identified more than $100,000 in direct savings, including $14,220 from 43 unused seats of one SaaS product and $85,662 a year in unused SKUs from another. A person still approves any spending, contract terms, or messages sent to vendors.

AIxAI has released Grok Bot for enterprise today, and it is free for all Grok and Cursor enterprise customers for the next two weeks. Cursor's Michael Truell says deployments have felt like onboarding thousands of capable teammates, calling it the most internally adopted and most powerful AI product the company has seen so far.

AISpaceXAI apologized for Grok issues caused by an outage at its Memphis compute center this morning, and also apologized to affected compute partners. All systems have now been restored and are functioning nominally.

AIxAI describes Grok Bot as built around persistent agents that keep their own identity, memory, runtime, and tools, rather than disposable chat sessions. Its interface organizes around five objects: Bots, Chats, Prompts, Tools, and Artifacts. Each Bot's avatar shows its identity and lifecycle state, with hover revealing its current action.

AIxAI announced Grok Bot, a platform for creating autonomous AI Bots that run in the cloud and carry out tasks end to end inside tools teams already use. Today's release adds access, network, and audit controls so enterprises can govern Bots at scale, and Enterprise customers can get Grok Bot free for two weeks.

AISpaceXAI, the account for xAI and Grok, shared a LatchBio blog post analyzing the biological capabilities and safeguards of Grok 4.6. The post itself provides only a link, so the findings are not summarized here.

AILatchBio evaluated Grok 4.6 on biosecurity monitoring and adversarial biological tasks, finding it correctly detects and refuses dangerous queries, including maliciously obfuscated ones. The model also still answers beneficial scientific questions, according to the post's account of the results.

AIGrok Bot is now available to all standard Grok and Cursor subscribers, with SuperGrok and Cursor Pro subscribers included. Cursor's Michael Truell says users are delegating tasks ranging from running small e-commerce businesses to testing production software. Weekly usage limits are also being reset for all users.

AILiveKit announces that developers can build voice agents using Grok Voice models, with full ZDR support. LiveKit's example patient intake agent cascades Grok STT, Grok 4.3, and Grok TTS through LiveKit Inference in a single AgentSession, with no separate API key or billing.

AIDylan Patel argues that Anthropic and OpenAI are on track to control most of the world's usable compute by 2028, because they can monetize compute better and outbid others. He estimates the labs grew from about 2 gigawatts each at the start of this year to above 5 gigawatts by year end. The discussion also covers whether roughly $10 trillion of AI capex could trigger a sovereign debt crisis through higher interest rates.

AIxAI has made Grok Voice Think Fast 2.0 available through its API and in the Agent Builder for building voice agents. Developers can build, tune, and deploy voice agents at console.x.ai, with more details in the linked announcement.

AIStarlink is using Grok Voice to handle over 15,000 inbound customer support and sales calls per day. Grok diagnoses hardware issues, ships replacements, and fulfills over 3,000 orders a week across voice calls and chat.

AIGrok Bot access is opening to a small set of enterprises this weekend. Interested companies can reply to request an in-person onboarding visit to their San Francisco office tomorrow or Monday.

AICursor's acquisition by SpaceX has officially closed, and Cursor will join the SpaceXAI team. The stated goal is to help make Grok the world's most useful AI and to improve Grok Build, Grok Bot, Grok API, Cursor, and more.

Why it matters: The acquisition closing ties Cursor's coding tools to Grok's product line, which changes how the two products may be developed and sold together.

AICursor has been acquired by SpaceX, completing a process that began in April when the two companies announced a partnership to accelerate model training. The post says the deal gives Cursor access to what it calls the largest GPU fleet in the world, which it expects to yield more capable models at lower cost. It cites Grok 4.6, released Wednesday, as an early look at what the companies can build together.

Why it matters: The post confirms a completed acquisition and links it to GPU access and cheaper model serving, which explains why the deal matters for coding tools.

AIAman Sanger, owner of Cursor, posted that a 1.5T model "could" and that bigger, better models are on the horizon. The post is short, offering no benchmark scores, release dates, or pricing, and it links to Grok 4.6 from @SpaceXAI, which the source describes as a significant improvement over Grok 4.5 at the same price.

AIGrok 4.6 is released as a significant improvement over Grok 4.5 at the same price, according to the announcement. The author says it is significantly better at difficult tasks and knowledge work, combining Opus-class intelligence and polish with low cost and high speed. A comparison table shows Grok 4.6 High scoring 61 on the AA Intelligence Index, versus 56 for Grok 4.5 High, and 1753 on GDPval-AA v2, versus 1526.

AIAman Sanger of Cursor says each AI product wave produced a dominant player, naming OpenAI for chat, Anthropic for coding, and welcoming SpaceXAI for general knowledge work. The post links to Grok Bot, described in quoted context as an early-beta AI teammate that signs into tools, uses them like a person, and returns finished work.

AIGrok Bot is now available in early beta as an AI teammate that signs in to your tools, uses them as you would, and returns finished work. The post frames it as an early step toward capable, delightful digital colleagues.

AICursor's Aman Sanger says the new model is an enormous improvement over Composer 2.5 and was trained entirely from scratch with the SpaceXAI team. The quoted Cursor post identifies it as Grok 4.5, Cursor's most powerful model yet and the first built for more than software engineering.

AICursor co-founder Michael Truell announced Grok 4.5, a model trained with SpaceXAI that the post calls Opus-class, fast, and low cost. He says it is a significant step up over Composer 2.5 and has become the daily driver for many on the Cursor team. A benchmark table shows Grok 4.5 at 83.3% on Terminal-Bench 2.1 and 78.0% on SWE-Bench Multilingual, with the post saying more releases will follow.

AIMckay Wrigley congratulated the Cursor team on more than three years of work and said he is excited to see what they build with compute from SpaceX and xAI. He noted he still keeps the original open-source Cursor repo on his laptop. Background posts from him describe Cursor as his full-time IDE, citing codebase search as a major productivity gain.

AISpaceX has exercised its option to acquire Cursor in an all-stock transaction, with the stated goal of building the world's most useful AI models. Over the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.

AICursor's Michael Truell says the company is partnering with the SpaceX team to scale up Composer, calling it a meaningful step toward building the best place to code with AI. The quoted SpaceX post says Cursor gives SpaceX the right to acquire Cursor later this year for $60 billion, or pay $10 billion for the work together. It also cites SpaceX's Colossus training supercomputer, described as a million H100-equivalent system, as a source of training capacity.

AIARC Prize reports that the top Kaggle entry reached 24% on the ARC-AGI-2 private dataset at $0.20 per task, and that all winning solutions and papers are open source. The top verified commercial model, Opus 4.5 (Thinking, 64k), scored 37.6% at $2.20 per task, while a Poetiq refinement on Gemini 3 Pro reached 54% at $30 per task. The author argues that refinement loops are the main driver of 2025 progress, and says ARC-AGI-3 is planned for early 2026.

Why it matters: The post links 2025 competition results to a broader argument about refinement loops, showing how benchmark outcomes are being read as evidence of AI reasoning progress.
