I once taught an image processing course at Tesla. Now I am sharing it with you here—the journey of photon-to-numeric, narrated by Grok Grok Bot.

Curious about the journey from photons to the image or video on your phone? I made a video with Grok Grok Bot, Grok Imagine, and Voice explaining the physics and theory behind it—100% on my phone just chatting. Part I: photons to digital signal Part II: digital signal to pretty picture Pro tip for Grok Grok Bot: Ask it to QA every single frame before handing it back. It saves QA time so you can focus on high-level direction. All technical visualization, including relinearization of the video footage from Grok Grok Imagine to be physically accurate, is done by Grok Grok Bot. Update: added more technical details with higher quality encoding for completion.

Thanks to the Quality mode of Grok Imagine I was able to make this video which I couldn't do before. Image: Quality mode of Grok Imagine Editing image: Grok Imagine Animation with extension : Grok Imagine

Grok Imagine has an excellent image editor. The video below was created from a single image (created by Grok Imagine) that I modified using Grok Imagine's image editor. If you have any trouble using it, let me know in the comments below. I'll try to help you.

Grok Bot can recreate any viral video from the link 🤯 How it works: I send Grok Bot a link to an AI clip. It watches the video and writes a prompt to recreate it (with any changes I want). Then it uses Grok Imagine to generate the new video! I tried it on the subway trend 👇

Grok Bot is the best AI agent right now It gives you an army of agents that can do work for you around the clock 24/7 If you set it up correctly, you gain super powers In this video I cover setting up Grok Bot, use cases, plugins, and what makes Grok Bot so good:

Nice thing about Grok Grok Bot is that you can throw any idea into the Grok Bot, even a backburner one. The Grok Bot will just implement it, waiting for you to review. Today I saw my kid struggling to understand how to break down a number into power sums, and I could not find a good video to explain it, so I asked the Grok Bot to make one. It even made a cheerful voice using the Grok voice API.

In collaboration with Munk School, I am sharing a ten-lecture course I taught at University of Toronto this past year. The course is called “Hitler and Stalin Today.” Watch the first lecture here:

Had a lot of fun animating our new Grok Bot icon. It's entirely made in code, with every state, shape and expression able to morph smoothly into the other. And of course, I made it with Grok Build.

This is the story of life, I used an image I created with Grok Imagine. Then, thanks to the video extension of Grok Imagine, I was able to have sequences up to 30 seconds long (3 x 10 seconds).

You know a technology is good when you don't even realize you've used it. For this scene, - I created the character as an image with Grok Imagine, then the landscape with Grok, and combined everything using Grok Imagine's image references. - I then used video extensions to avoid cuts and style changes. The character is perfectly integrated into the scene, proportions respected and style preserved.

Another example of video extension using the latest Grok Imagine update: I created an image in Grok Imagine. I animated it. Then I clicked on video extension: you can choose 6 seconds or 10 seconds, write an animation prompt, and select the starting image. This ensures perfect continuity of the scene: fluidity of the image and sound atmosphere (music and sound effects).

You’re using Grok Bot, but you probably don’t know the minds behind it. So I made GROK ME: a small social experiment that matches you with a builder, creator or supporter from the Grok universe. Built with Grok Bot, obviously. Huge respect to Elon Musk & the entire team pushing this forward. Find your match →

Precise Edit is now available on Grok Imagine. It allows you to easily edit a specific part of an image without changing the rest. Grok automatically splits your image into multiple segments that you can select and edit individually. A super useful upgrade. Try it now!

It's so easy to invent a world with Grok Imagine. From one image to the next, we let ourselves be carried away by Grok, it develops the imagination: "what if I added this?" "what if I changed that?" ...

A 30-second scene created from an image (created by Grok). I animated it for 10 seconds (without a prompt) and then clicked on "Extend Video" twice. Grok decided on the animation, and I think he did a great job. Grok Imagine

For this video created from an image in Grok Imagine, I combined two techniques: - the image editor from Grok Imagine - starting from a frame of a video to create other videos.

I'm proud to present this video created with Grok. Here are the main steps in the making of this video: 1. I wrote a draft script by hand. 2. I reworked the script with Grok to eliminate inconsistencies and add technical details (what I have them say about the Apollo missions and the stones is accurate). 3. Grok broke it down into scenes. 4. I switched to Grok Imagine's Agent mode: transforming each scene into a prompt. 5. I animated each scene in Agent mode using video, as well as cropping and image selection. 6. I edited it. Here's the result; it's hard to call it AI. I look forward to reading your comments.
