xAI’s next Grok foundation model is moving from training into fine-tuning at 1.5T parameters, three times the size of the current 0.5T production model. Musk says Cursor data was added and public release is 2 to 3 weeks away.
Grok now supports four new connectors — Vercel for web deployment, Canva for visual content creation, Gamma for presentation design, and S&P Global for real-time market data. The expansion puts Grok in direct competition with Anthropic's MCP ecosystem and OpenAI's ChatGPT Connectors in the growing AI agent integration market.
xAI has released an early beta of Grok Build, an agentic CLI tool for coding, building apps, and automating workflows, available now to SuperGrok Heavy subscribers. The announcement drew over 41 million views, signaling massive developer interest.
Grok has expanded its Connectors feature to all subscription tiers, enabling every user to integrate email, calendar, presentation tools, and Notion directly into their AI workflows.
xAI has launched Grok Voice Think Fast 1.0, a voice agent optimized for enterprise customer support scenarios, emphasizing low-latency responses and natural conversation flow.
Elon Musk confirmed the dissolution of xAI as an independent company, folding Grok and all AI products into SpaceX under the new SpaceXAI division. The move follows the $1.25 trillion SpaceX-xAI merger and marks a major restructuring in the AI landscape.
xAI is providing Anthropic with full access to Colossus 1, an AI supercomputer with 220,000+ NVIDIA GPUs. The deal immediately doubles Claude Code rate limits across all paid plans and removes peak-hour throttling for Pro and Max subscribers.
The Center for AI Standards and Innovation (CASI) secured agreements with Google DeepMind, Microsoft, and xAI to review frontier AI models for national security risks before launch. The policy shift follows alarm over Anthropic's Claude Mythos autonomous cybersecurity capabilities.
xAI has released Grok 4.3 on its API, claiming top spots on agentic tool calling and instruction-following leaderboards, and ranking #1 in enterprise domains such as case law and corporate finance. It supports a 1M token context window at $1.25/M input and $2.50/M output.
A Twitter user exploited indirect prompt injection using Morse code to trick Grok AI into executing a command that transferred 3 billion DRB tokens worth roughly $200,000 to the attacker's wallet via a connected trading bot.
xAI officially launched Voice Cloning through its API, allowing users to clone a custom voice in under 2 minutes or select from 80+ pre-built voices across 28 languages for voice agents, audiobooks, and game characters.
On day four of the Musk v. Altman trial, Elon Musk testified that xAI used distillation of OpenAI's models to train Grok, calling it 'general practice.' The admission raises ToS violation questions and may undercut his own case against OpenAI.
