xAI (SpaceXAI) and Cursor have launched Grok Bot in beta, an AI agent app for Mac and iPhone that signs into existing tools to complete work autonomously. Access is currently limited to top-tier SuperGrok and Cursor subscribers, with wider availability rolling out within 10 days of launch.

The @ai-sdk/xai package version 3.0.121 adds support for xAI's grok-imagine-video-1.5 model, including native 1080p resolution for text-to-video and image-to-video generation. The update also introduces referenceVoiceIds for reference audio and fixes a routing bug in reference-to-video mode.

xAI's Grok 4.6 scored nearly even with OpenAI's GPT-5.6 Sol Max on the Artificial Analysis Intelligence Index, while Meta launched Muse Glimmer, a laptop-runnable open-weight model. Musk says Grok 4.7 will arrive in three to four weeks and claims it will 'exceed all current models.'

xAI released Grok 4.6, a confirmed 1.5T-parameter model built on Grok 4.5 with heavier training on long-horizon agentic tasks. It powers the newly launched Grok Bot product and scores 61 on Artificial Analysis's Intelligence Index at $2/$6 per 1M input/output tokens — well below frontier competitors.

xAI's Grok 4.6 ties OpenAI's GPT-5.6 Sol on the Artificial Analysis Intelligence Index with a score of 61, trailing only Anthropic's Claude Opus 5 and Claude Fable 5. Pricing remains at $2/$6 per million tokens, undercutting both competitors by more than 60 percent.

xAI released Grok 4.6, claiming intelligence on par with OpenAI's GPT-5.6 Sol and just one point behind Anthropic's Claude Fable 5 Max on the Artificial Analysis Intelligence Index. The model is priced at $2 per million input tokens and $6 per million output tokens, with a faster variant at double that rate.

Vercel released @ai-sdk/xai version 3.0.119, a patch update that adds model IDs for Grok 4.6 and introduces support for an 'xhigh' reasoning effort parameter. The change lets developers using the Vercel AI SDK target xAI's newer model directly through the existing provider interface.

Vercel shipped @ai-sdk/xai version 2.0.86, a patch release that adds support for Grok 4.6 models in its xAI provider integration. The update lets developers using the Vercel AI SDK route requests to Grok 4.6 without custom API handling.

xAI has released Grok 4.6, a text-and-image model featuring a 500K token context window. The model is priced at $2.00 per million input tokens and $6.00 per million output tokens, and is available now through OpenRouter's API.

Vercel released @ai-sdk/xai version 4.0.36, adding support for xAI's grok-imagine-video-1.5 model with native 1080p resolution and a new referenceVoiceIds parameter for reference-to-video audio. The update also fixes a routing bug that misdirected certain video generation requests.

xAI's new Imagine Image 2.0 lands in second place globally on both the Image Edit and Text-to-Image Arena leaderboards, trailing OpenAI's GPT-Image-2. The model ships with editing tools including Magic Wand, Multi-Ref Editing, and Smart Resize.

The Financial Times reports ByteDance is pretraining an AI model with up to 10 trillion parameters, which would make it three times larger than Moonshot's Kimi K3, currently China's largest model. The claim comes from anonymous insiders and has not been confirmed by ByteDance.

xAI has made Grok 4.3 generally available on Amazon Bedrock, marking xAI's debut as a Bedrock model provider. The multimodal model offers a 1 million token context window, configurable reasoning effort (none/low/medium/high), and runs on Bedrock's Mantle inference engine using OpenAI-compatible APIs.

Vercel released AI SDK version 3.0.106 for xAI integration, adding support for the Grok 4.5 model identifier and expanding input reference capabilities to include video files for reference-to-video generation workflows.

xAI has released Grok 4.5, pricing it at $2 per million input tokens and $6 per million output tokens — significantly undercutting Anthropic's Opus 4.7 ($5/$25 per million). Elon Musk claims the model delivers comparable performance to Opus 4.7 while being faster and more token-efficient.

Yann LeCun, former Meta chief AI scientist and founder of AMI Labs, called Elon Musk's xAI a "failure" that won't be able to compete with OpenAI and Anthropic. LeCun warned that AI labs are at risk of a "big bubble explosion" because current pricing doesn't cover operational costs, with services funded primarily by investors.

xAI has released Grok Build 0.1, a coding-specialized model with a 256K context window and unlimited text output. The model is designed for agentic software engineering workflows and powers xAI's Grok Build CLI tool.

xAI has released Grok Build, a coding agent and CLI tool positioned to compete with Anthropic's Claude Code and other AI coding assistants. The early beta is available exclusively to SuperGrok Heavy subscribers at $300 per month.

xAI is deploying Grok to Apple CarPlay following iOS 26.4's April 2026 update that introduced a Voice Control template for third-party AI chatbots. The move puts Grok alongside ChatGPT, Perplexity, Claude, and Gemini on 800 million iPhones, marking xAI's first deployment outside the Musk ecosystem.

xAI has released Grok 4.3, a reasoning model with a 1 million token context window and no output token limit. The model accepts text and image inputs, has always-on reasoning that cannot be disabled, and uses tiered pricing starting at $1.25 per million input tokens and $2.50 per million output tokens.

X has launched Grok-powered Custom Timelines for Premium subscribers on iOS, offering over 75 AI-curated topic feeds that can be pinned to the home tab. The feature uses xAI's Grok to analyze and label posts by topic rather than relying on keywords or hashtags, and arrives alongside the shutdown of X Communities.

xAI's Grok 4.20 scores 48 on Artificial Analysis' Intelligence Index—6 points ahead of Grok 4 but trailing Gemini 3.1 Pro Preview and GPT-5.4 at 57. The model distinguishes itself with a 78% non-hallucination rate on the AA Omniscience test, the highest recorded across any model tested.
