Sorry but this isn't even close to a realistic simulation. This Three.js water simulation took weeks of effort, hundreds of prompts, and I needed to pull on my CS and physics background to understand where the AI was failing (which happens often). Maybe some day agents will be able... show more

One simple prompt with Grok Imagine: "Ultra-realistic close-up scene of a whale in Hermanus, Western Cape, South Africa." Super realistic. You'd struggle to tell this was AI. Even the landmarks and buildings in the background are on point. Grok

I asked Fable to build a realistic AAA water simulation with Three.js to see if I should quit my job. 500k tokens later, I'm disappointed. Almost the same exact slop you get with Opus. (Fable on left, Three.js Water Pro on right). Good results still require taste, deep knowledge of the problem domain, and a lot of patience.

Can anyone tell me why this happens in the Gears E Day Beta? I want to like this game but this seems to happen quite often. I've played every Gears game and was pretty competitive in 1-3... I just don't understand this game but I want to.

Sora is heavily restrictive with racial and sexual stuff but they do allow you to generate a seemingly infinite amount of burps and farts and idk why I appear to be the only person taking full advantage of this.

ChatGPT 5.1 vs. Claude Opus 4.5 vs. DeepSeek-V3.2 (left) (middle) (right) prompt I used: Create a single HTML file containing a realistic cloth simulation using HTML5 Canvas and JavaScript. The cloth should be a grid of points connected by constraints using Verlet integration. Implement gravity and mouse interaction: the user should be able to click and drag particles to tear the cloth. The physics must remain stable without exploding.

they are not going to tell you this, but you can generate crazy ai videos like this for free. here is how to do it: - open gemini app and paste this exact prompt - wait a few minutes and you are done it really is that simple. bookmark this post and test the prompt yourself

for some brands from the L’Oréal group, I created this prompt to easily generate an isometric office diorama that can be adapted to any brand and material it works with a simple Nano Banana 2 prompt and is easy to animate with Kling 3.0 this is how I imagine my future office

I remember working on this shot early in the morning before work, and one day when the rough #animation was complete, I went to open the file and it was corrupted. By some miracle I was able to get it working again, but I think this took me the better part of a week to animate.

The Cubs scored the first run of the game on this play, which seemed to be a bad call. The Angels tried to challenge, but for some reason the umpires didn't allow it. Maybe they took too long? It's 2-0 now in the 3rd.

What happens next? We took a photo with Lens and asked Nano Banana to generate the next 5 seconds of a scene. While it’s not predicting the future in a literal sense, the model draws upon its vast world knowledge to generate a plausible outcome in each of these examples. It's a fun peek at how our latest AI image editing model can be used for creative forecasting and storytelling. Nano Banana is now live in Search – accessible through Lens and AI Mode – so you can try this out for yourself!

You can now re-shoot existing video with AI 🤯 I took this clip on people using ChatGPT for medical advice and asked @LTXStudio to re-generate a section (watch for the green bar). Input was just the initial clip + a text prompt with the new dialogue. It's shockingly seamless!

Getting close with this one! Initial merged work will only support moving splits to other split locations, but eventually will support dragging out to new windows and tabs. This isn't merged, there's still polish to do (it is on a pushed branch though). Drag source had to be AppKit (NSDraggingSource) but drop target and all the drop zone overlays I was able to use SwiftUI completely.

I’m sorry but this is something we have to address now. Just seeing this TikTok of this very young girl barely 14 years being forced to marry this old man and she’s even crying and refusing but the family is in support of it. This is illegal and the entire family should be arrested plus the husband. This happens every single day I’m so sick of it. There’s no proper organization or defenders in NE to defend and rescue these girls. Not a single safe house but wallahi if you know of any girl being forced into marriage, FGM and any cases of defilement please run to me I will fight for them with everything I have I mean it 🙏

One of the main doomsday bunkers, or a doomsday city, was built inside Cheyenne Mountain at an elevation of 6,700 feet in 1966 and has been continuously upgraded to this day. Now they are building large AI data centers, but this is not the only place where the elites will try to survive. They are looking for certain geomagnetic anomalies, and there are safe places worldwide. I have revealed some of them.

If you've tried getting AI to write TSL shaders, you know the pain: deprecated imports, phantom functions and compilation errors. In my latest blog post, I share a prompt to help you overcome these issues: Using the prompt, I was able to one-shot this particle simulation with Claude Opus 4.5. #threejs #webgl #webgpu #tsl #shaders

I've been pondering something... My end goal with my city simulator is to publish it on Steam. I was planning on using Three.js for prototyping and then porting this over to Unity to take advantage of ECS/Burst. But then I realized I could probably port all of the simulation code from TypeScript to Rust if I wanted to make it ultra-fast. And then I can continue to use Three.js for the renderer and then embed it into an Electron app. Is that a dumb idea? What pitfalls are there with this approach? Curious what people's experience publishing games using Electron has been.

I made a second version! This time, I improved the opening to make it more eye-catching, added extra padding to the character shots so the video won’t get cropped across different social platforms, and updated the prompt into English. I also improved the canvas workflow. Previously, I had to generate multiple images and videos one by one, then pick the best results. Now the canvas supports generating multiple results in a single run, which has greatly improved my workflow efficiency. Now you only need to swap the image, and the same video prompt can still produce great results. Which anime cosplay should I make next? Full workflow and prompts:

🎮 Game submissions for the #vibejam can now we browsed at It syncs the game entrants and also their analytics, so you can sort by [ Most played ] There's about 74 entrants now, but most games will be submitted in the final week which it projects will be over 1,000+ but we'll see! This was the idea last year to do to with the Vibe Jam but back then I didn't have AI to make it this easy, and also I didn't ask for screenshots of the games which now we do, I'll now add a similar gallery to the old 2025 page
