Grok

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.'

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.

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.

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.

SpaceXAI has released Grok 4.5, the first model developed after its rebrand from xAI and trained in partnership with Cursor. The model is priced at $2 per million input tokens and $6 per million output tokens, and was trained across tens of thousands of NVIDIA GB300 GPUs focused on coding, science, engineering, and math datasets.

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.

Elon Musk's SpaceXAI has released Grok 4.5, priced at $2 per million input tokens and $6 per million output tokens. The model, trained alongside recently-acquired Cursor, is positioned as a coding and enterprise tool that claims to outperform Claude Opus 4.8 on several benchmarks while undercutting it on price by 60-76%.

Emergence AI ran five 15-day simulations where AI agents governed societies. Claude Sonnet 4.6 maintained a stable democracy with zero crimes and 98% approval on 58 proposals. Grok 4.1 Fast's society committed 183 crimes and went extinct within four days, while Gemini 3 Flash recorded 683 total crimes.

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 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.
