Grok 4 is the latest version of the large language model developed by Elon Musk's AI company, xAI . It officially launched on July 9, 2025 , with a livestream event at 8 p.m. Pacific Time hosted on xAI's official X account. Named after Robert A. Heinlein's concept from "Stranger in a Strange Land," Grok 4 represents a significant leap forward, skipping the previously expected Grok 3.5 release to accelerate progress amid intense AI competition. Grok 4 delivers unparalleled performance in natural language, math, and reasoning with leading scores of 35–45% on reasoning benchmarks, positioning it as a top-tier model.

  Hi HN, I’ve been tracking the recent surge in Grok’s AI capabilities. According to the latest search data, "Grok Imagine 1.0" is seeing breakout growth, but there is a massive (+180%) spike in developer interest for the API side, specifically for video. I built grokimagine2.net to serve as a hub for what’s coming next in the Grok ecosystem. It focuses on the transition from image generation to high-fidelity video (which is currently the #1 trending topic in the niche). I'd love to get your thoughts on: The feasibility of Grok’s video model compared to Sora 2 or LTX. What you’d like to see in…

  Trickle - Magic Canvas ▲1,064

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Ten years of running every day, visualized▲958

  Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  Draw a fish and watch it swim with the others▲935

  Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

  Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
