xAI / Grok

The DOJ moved to dismiss an NAACP lawsuit against xAI, arguing that shutting off its gas turbines would threaten military operations. A DOD official stated Grok is one of four models supporting mission-critical work on classified networks, including recent strikes on Iran. The NAACP sued because xAI runs unpermitted turbines at its Colossus 2 site in Mississippi—turbine count grew from 27 to 57 since April, with a 111% spike in nitrogen oxide emissions. The post doesn't specify which national security statute the DOJ is citing.

Days after its historic IPO, SpaceX agreed to buy AI coding startup Cursor for $60 billion in stock. Cursor was about to close a $2B round at a $50B valuation from a16z, Thrive, and Nvidia. SpaceX told IPO investors its AI addressable market is $26 trillion and wants the deal to help its xAI-built AI unit catch up with major labs. The transaction is expected to close in Q3. The post doesn't spell out product integration plans, team retention, or regulatory approvals.

xAI upgraded its image-to-video model to 1.5, now generally available via API with a Fast variant on Grok and mobile apps. A 6-second 720p clip takes about 25 seconds, nearly twice as fast as the previous 40+ seconds. Audio is generated in the same pass—ambience, effects, and dialogue land on the action with better lip sync. Motion holds up over longer clips with fewer warps and more believable weight. Three workflow features are rolling out: Projects for organization, parallel multi-agent prompting, and library search. The post doesn't disclose training data scale or pricing.

xAI shipped a terminal dashboard for Grok Build that lets you monitor and interact with multiple coding sessions on one screen. Sessions are grouped by state—blocked ones rise to the top—so you handle approvals and questions inline without switching contexts. You can peek at output, reply, dispatch new work, and jump into any session. Closing the dashboard leaves everything running; reopening it restores all sessions. Install via curl -fsSL https://x.ai/cli/install.sh | bash, then run grok dashboard or hit Ctrl+\.

xAI added a plugin marketplace directly inside Grok Build, so you can browse, install, and update plugins without leaving the terminal. Each plugin bundles skills, slash commands, agents, hooks, MCP servers, and LSPs. The launch lineup includes MongoDB, Vercel, Sentry, Chrome DevTools, Cloudflare, and Superpowers. Every remote plugin is pinned to a specific commit SHA and verified at install time. Developers can publish their own by submitting a PR to xai-org/plugin-marketplace. The post doesn't mention any review process or revenue split.

xAI brought in an executive from SpaceX’s Starlink service to run the Grok training team, replacing college-aged engineer Diego Pasini; the RSS snippet does not disclose the executive’s name, tenure, or training process.

SpaceX disclosed a cloud services agreement with Google: Google will pay SpaceX $920 million per month for computing capacity tied to xAI data centers, while the post does not disclose contract duration, GPU scale, or delivery terms.

The title says Google will pay SpaceX $920 million per month for compute capacity at xAI data centers; the RSS snippet does not disclose contract duration, GPU scale, or the capacity delivery mechanism.

xAI launched Grok Build 0.1 in May 2026 as a coding agent built around parallel subagents; the post does not disclose benchmark results, cost figures, or specific privacy-policy terms.

OpenRouter spent $482 on inference to run 11 LLMs through a 30-round real-time decision challenge, where Claude and Grok models led on decision speed and task success, while several high benchmark models underperformed on real-time scheduling.

UK MP Jess Asato sued Musk’s xAI over fake sexual images, using the claim to test whether AI model makers are liable for system outputs; the post does not disclose the model, generation mechanism, damages sought, or court timetable.

xAI partnered with Vapi to make Grok the default engine for 12 core voices, covering more than 2.5 million voice agents, and Grok Voice ranked first in Vapi’s independent blind test.

xAI released grok-imagine-video-1.5-preview via its API, letting users turn one still image into 720p video while controlling camera movement, pacing, and sound effects with natural-language prompts.

Ethan He says a small xAI team built Grok Imagine from zero to one in 3 months, and the episode discusses video agents, audio-video alignment, inference speedups, and the storage, egress, and GPU-hour costs behind large video datasets.

SemiAnalysis says xAI dropped JAX GPU and moved to a C training framework written with Grok Build; the snippet claims xAI’s JAX stack had MFU below 10%, but the post does not disclose reproducible benchmark conditions.

xAI released grok-build-0.1 as a public beta through its API; the same model powers the Grok Build CLI, targets agentic coding, and is priced at $1 per million input tokens and $2 per million output tokens.

xAI released Grok Build 0.1 in public beta through the xAI API for agentic coding tasks, with throughput above 100 tokens per second and pricing at $1 per million input tokens and $2 per million output tokens.

Elon Musk said the 1.5T-parameter Grok V9-Medium has finished training, will enter reinforcement learning in a few days, and is planned for release in two to three weeks. Grok Build supports up to 8 parallel sub-agents, a 256K-token context window, Plan Mode, Arena Mode, MCP, and ACP.

xAI opened Grok Build Beta to all SuperGrok and X Premium+ users, with Plan Mode, Imagine-based image and video creation, and a CLI for automation or orchestrator workflows at x.ai/cli.

Anthropic is on track to record its first profitable quarter ahead of OpenAI and xAI; the RSS snippet does not disclose the quarter, revenue, profit figure, or accounting basis.
