Made this short clip with @grok's new director bot, inspired by John Baldessari's dot works. I was really impressed by how the agent handled the consistency of the dots: "To keep the faces hidden, I'm adding the dots myself over every frame after the scenes are generated, rather than counting on the video model to keep them in place."
A new bot called "Director," by Xi Yan, showed up in the Grok Bot Marketplace. It's a video director that takes a brief and plans, shoots, cuts and delivers short films, ads, explainers or music videos. Import it, it comes with a pack of video skills. x.ai/bot/marketplace/bots/vi…

Big day for @Starlink Mobile…
We announced an agreement to acquire a nationwide low-band spectrum license portfolio that will pave the way for @Starlink to become a major mobile carrier in the US. With this new spectrum and our Gen2 constellation, Starlink Mobile can ensure Americans have access to high-speed mobile broadband no matter where they are → spacex.com/updates#starlink-…

This was unexpected. Grok 4.7 scored 100% on my music error detection test, the same as GPT-6 Astra.
Grok 4.7 (High) on the Bach Benchmark. Not very impressive. Few outright errors, but lots of awkwardness.

Very cool to work with @PJaccetturo and his team at Genre AI on this pilot scene of the Odyssey. If you have any questions about how to use Grok @imagine for cinematic workflows, drop them below. We're always looking to improve, let us know what tools you're missing or ideas you have 🙏

xAI's Grok Imagine Image 2.0 takes #4 on the Artificial Analysis Text to Image Leaderboard, the highest ranked model outside OpenAI, a 14 place climb over the previous generation, and lands on the Pareto frontier for quality vs price Grok Imagine Image 2.0 is xAI's latest image model released in August. The model supports text to image, image editing, as well as multi-reference generations with up to five input images. Grok Imagine Image 2.0 is a large step up on the previous generation grok-imagine-image-quality: it climbs from #18 to #4 in Text to Image and from #16 to #10 in Image Editing, closing the gap to the leaders on every Text to Image capability and use case we measure, with the largest gains in Knowledge, Text Rendering and Lighting. Grok Imagine Image 2.0 is available through the xAI API as grok-imagine-image-2.0, in Grok Imagine on grok.com and the Grok apps, and through fal and Replicate. Congratulations to @spacexai and @elonmusk on the release! See below for our analysis and example outputs of Grok Imagine Image 2.0 in the Artificial Analysis Image Arena 🧵

building models that understand us requires building models of us - super excited to share some work in that direction and hope people find it useful!
For AI to work with us, it needs to understand us Today, we're introducing Persimmon, the first large-scale model designed to realistically simulate how people talk and interact

This is why companies that don’t pull the plug on you matter: OpenAI will cut Cursor after the acquisition, then keep using X to promote their models. The asymmetry is the whole story.

Providers start an API business before they know which apps will matter. Cursor was one of those apps, used the API well, and the provider made a lot of money off it. Asking why they “allowed” Cursor from day one gets the sequence backward. First comes the API, then the apps, then the scale. The scary part isn’t Cursor. It’s the precedent: downstream startups now have to compete with the market and with their own provider (OAI in this case) flipping on them.

Grok Bot is now available to everyone with a standard Grok or Cursor subscription. It's grown faster than any product we've seen. It's been particularly exciting to see the range of jobs people delegate to Grok Bot, from running small e-commerce businesses (including support, advertising, inventory, finance), coordinating customer events (directly pinging and working with dozens of human coworkers), testing production software, and completing large, mundane parts of users' day-to-day work.
All SuperGrok and Cursor Pro subscribers now have access to Grok Bot. We're also resetting weekly usage limits for all users. Enjoy!

I gave Grok @bot a link to the post below and asked it to take up the cinematography challenge. Direct the film entirely through the chat casually and nothing else. Pretty wild.
Homer had a lyre. You have Grok Imagine. Create a compelling scene from Homer’s The Odyssey that shows what Grok @Imagine’s video and voice capabilities can do. We’re awarding $100K, $50K, and $25K to the top three videos submitted by quoting this post. 🧵
