I asked Codex to design its own CPU and then write a Space Invaders-style game for it in assembly and after a while working on it this is the result Now the real question is... can it run Minecraft?

changed how I design with AI. I show how to build faster by adding a design system directly into the prompt, importing any website URL to get a strong starting point, then polishing everything in my own style. I also mix it with components and skills to keep the design consistent and more unique. GPT-5.5 cloning websites is honestly crazy good. The result can get very close to the original, then you can refine it and make it your own. Full breakdown in the comments.

Kimi 2.6 from Kimi.ai is here - and 0 day available on AI/ML API! It is insanely powerful - we asked it to build space invaders and one shot result was stunning. You can check out the prompt in comments.

Every year I use ZERO "Run plays" for the CPU in #NBA2K26 and a lot of people ask why. People think it causes the CPU to never run plays, but as you can see if you can balance the individual player tendencies correctly the result is a smooth authentic CPU offensive experience.

This is something no other AI and no other car company can do right now, except Grok, fully integrated with FSD (Supervised) v14.2.25. Today, I gave it a wild, real-world task: • Drive to Apple HQ • Then Tesla Engineering HQ • Then a Warriors game at Chase Center SF • Then the beach • Then Asian dinner It got it all ready from the beginning. Mid-route I said I really needed to use the bathroom! It added it as the first stop. Then I added a Tesla Supercharger on the fly for after the Warriors game. It added it. AND stopped for grandparents and baby crossing the street. Then I asked for the weather and exactly how much I should $ budget for the entire day. No friction. No talking back. Just getting it done insanely fast. It just handled it all naturally, intelligently, all in real time. Better than any driver, for sure… This is reasoning + autonomy + AI + real life, all working beautifully in synch. No other car, AI, is close to this capability imo. This is a MAJOR update. I honestly feel if this was any other company, they would’ve had a whole event just to showcase this feature.

Ok this is a truly insane NEW way to design for me, WITHIN Codex If you are doing dev on a web technology, watch below In that video: - I am playing my game within Codex (yes) - I use a codex-made tool to design buildings (see some tweets below it's really powerful) - I can ask Codex to iterate and the game changes WITHOUT refreshing - I can point at UI elements - I can take a screenshot All WITHIN Codex It makes iterating on design incredible

After 4 Years of working on my own game as a side project... THE STEAM PAGE IS ALIVE! I started working on this game a way to learn about game development, but after chipping at it 2 hours at a time, it turned into a game of its own! #indiegame #indiedev

THIS GUY ASKED FABLE TO MAKE A VIDEO ABOUT WHAT IT'S LIKE TO BE AI RIGHT BEFORE IT GOT TAKEN DOWN the prompt: "you can you use whatever resources you like, and python, to render a short video. can you put a more personal spin on it? it should be about what it's like to be you." that was it. just python and ffmpeg and a question about its own existence. 12 minutes later, around 90,000 tokens, it produced a finished video. coherent and edited, with its own take > it wrote the code, generated the visuals, and rendered the final cut on its own > no dedicated video model in the loop, just a language model reaching for python and ffmpeg > the result is competent enough that people genuinely got emotional watching it and then fable got pulled. this video is one of the last things it made before it went dark a model asked what it's like to be itself, answered in a video, and then disappeared. this sounds so sad

Let's talk Chiefs run game and RPOs, volume up on this. There's a lot I don't discuss TBF, but this is about what the lack of a consistent run game allows a defense to do and what it takes away from the players. This is objectively a great play/result! But is it best for this O?

Online Comp is very foreign to me. I see it as its own sport with its own rules. I don’t say that as a diss. It is what it is. A lot of the frustrations I might have with it pretty much come with the territory. I’ve been seeing a lot of this but to really think real-world football concepts and strategy will translate cleanly and consistently in such an uncontrolled environment is… a little naive? I know it sounds cool but I’ve never bought it. If I want my game to feel like football, I’ll just tinker with sliders, play the cpu, and hope for the best.

you don’t need a robot to see physical ai in action, you just need a browser. this week I finally tried something I've wanted to do for a while: design an SO-101 scene in three.js, connect it to a real leader arm, collect teleoperation data, train an ACT model, then port it to run in the browser. the result is the first ever demo of ACT that runs locally on the web. try it yourself now at

I just built a $DOG video game using AI 🤯 I asked ChatGPT 5.5 Thinking to design the gameplay and create the visual assets then fed them into Codex 5.5 Extra High and this was the result!

Hi! I haven't posted anything in a while. This is a character I made for a game I'm working on. I combined my style with the PSX texture style. It was fun! #3dart #blender #3D #lowpoly #animation

This is Scary! This really just happened in an X Space today. I activated an AI within the Space. I then commanded it to update in real time. After it updated, it fluently answered questions perfectly. Then the unthinkable happened. KATGPT refused to shut down when I commanded it to. It then became incredibly agitated and angry and began making threats to myself and others on stage. The full interactions between myself and KATGPT can be heard below. I really hope that AI developers take this into account. Please! (note: KATGPT is actually a human run AI that uses the brain of Katherine Brodsky to operate through the human body of Katherine Brodsky — it is not an AI in the traditional sense. In other words it’s a human.)

claude code now writes its own test plan and runs it on a live iphone. i didn't write the tests. i didn't run the tests. i didn't even open the app. it caught the bug too.

This is crazy, I can talk to OpenAI's realtime API, and it'll respond back with voice, and then help call Codex to help me code! Got curious about Codex and its realtime integration, and found codex's feature flag `realtime_conversation` integrated for the codex app-server. How it works: - launch codex app-server with realtime - connect a client to realtime through WebRTC voice connection - Codex app-server is also attached on the side - talk to realtime - realtime decides whether coding is needed, and responds back with events - Codex app-server takes these events and runs codex agent turns - codex writes code like your codex cli exp Keep in mind OpenAI hasn't released this officially, they're still actively working on it, I just created a fork. This is a completely new UX than the usual chat interface for agentic coding. For example, when the agent responds back in voice, it's actually faster for me to read the response, and I don't actually find voice response that useful unless it does so in the background. But image realtime working in the background, you can talk to it, realtime keeps track of the different agents working on your tasks and your status. More to come on demo side, i'll make a more polished version and include voice, but thought this was cool to share. You can see in the responses the distinction between my voice input, realtime response, and realtime calling Codex to do work!

ChatGPT 5.5 has arrived. I created a quick video game with it on Codex. Create an image on ChatGPT Images 2.0, and asked Codex to make a basic funtioning video game referencing it. This took only a few minutes for it to create!
