Unity 6 + Opus 4.8 built a Minecraft-style game with just 2 prompts 😱 The first prompt took around 15 minutes. The second prompt took around 40 minutes. I wrote down everything I wanted for the first version, GPT expanded it with more details, and I sent it to... show more

Cool stuff: This weekend I vibe-coded an entire multiplayer game built entirely around "prompting", think Minecraft but with prompts! 🤯 It's the first game I've made where my friends and I spent 5 hours straight playing, it was so fun and unique. This map was 100% empty!

Claude Opus 5 just one-shotted this FPS. Less than 1 hour from prompt to playable demo. Every weapon, enemy, mechanic and environment was generated from scratch. Prompt below 👇 There is no prompt below, because the first section is exactly the kind of post I’m tired of seeing every time a new model drops. A flashy demo, “one-shot” in the caption, “built in under an hour”… anything to farm impressions while conveniently hiding the actual process. If it was really made from a single prompt, show the prompt. That’s what I do on this account. When I claim something is a one-prompt prototype built with GPT-5.6 Sol Ultra and Codex, I share the prompt publicly so anyone can verify it. AI is already making game prototyping incredible. We don’t need fake “one-shot” stories to prove it. Original footage:

Opus 4.5 is absolutely goated. I built AN ENTIRE VIDEO EDITING APPLICATION FOR WINDOWS IN ABOUT AN HOUR. No tricks. No special prompts, no prompt driven dev. Just me, Visual Studio Code, and Opus 4.5 having a convo via the mic. I feel like this is what we were promised, and it's here.

GPT 5.5 just buried opus 4.7 I had it build a pokemon style battle app. 1 prompt. the opus game crashes 90% of the time and Ui is absolute garbage. GPT 5.5 one shotted a masterpiece. Time to cancel anthropic sub?

SOMEONE VIBE CODED A FULL PC GAME 100% prompts with no code the stack: - built entirely in Cursor - 90% Grok 4.5, rest Opus 4.8 and GPT 5.5 - switched to Grok 4.5 for speed and cost - built on Godot - art generated with ChatGPT Images through his own custom tool Act 1 is already playable this is what vibe coding actually looks like now

💡What if I could fully turn an existing full-scale VR/MR game into a mini tabletop game? Honestly, this just took 6-7 prompts + a few android permission changes to enable hand tracking. The results 🤯 and this used to take me a while because I had to manually resize and adjust everything before I could even make it work. This is exactly why Unity AI and their exposed MCP tools are such a big deal for developers.

Last year I built a full Unity VR/MR demo for our talk and the Meta booth, and it took me around 3–4 weeks to complete. This year, with only a week left before GDC, I was definitely feeling the pressure. Surprisingly, I ended up building a full VR game with AI in just one day. The tech stack 👇

I applied Matt's prompt, ran it for a little over ten hours. About 1.3 million tokens on Opus 5. It created the game. I also made a video of it using Opus 5. Here's the video (and in my reply to this is a link to the actual game so you can play).

this week at Replit ⠕ i built this cute valentine’s day app! Inspired by pauline digibouquet 🌺 this was the first time i actually sat down, took the time to mock up a design and then start building. i think it came out so much better this way 💓

I used Cursor to vibe code a simple fishing game prototype on the Unity Engine. Here's my learnings: - I did not use any Unity MCP for this. The game was built entirely by Cursor models (Sonnet 4.6 for execution and Opus 4.6 for planning) - The model was able to set up the game, getting the basic game mechanics working fairly quickly - I had to use the Unity Game Editor UI to attach components to the in-game objects manually, but it was quite easy to follow the instructions given by the Cursor model - Unity Editor is huge and slow! Compared to Godot, I find the UI really clunky I feel tired looking at it - Unity Assets Marketplace is amazing, there are so many amazing art assets there (like the ones I am using for this game). This is probably the biggest strength of Unity. - I had some issues with restoring checkpoints, probably because of how Unity Game Editor UI being really clunky and I had to manually adjust things in the Editor, which the model doesnt have knowledge of Overall, the results turn out pretty decent, but it was a rather frustrating experience, especially when I had to debug issues or rollback changes. I'll explore more vibe coding on Unity but for now, I think I prefer Godot as a game engine. I just wish there is a Godot Asset Marketplace!

Got introduced to , an AI code assistant specialised for Unity by Julian Park and after dabbling with it for a day, I am really impressed with how good it is for vibe coding on the Unity Game Engine. Bezi early impressions: - Bezi works direcly on Unity with a Plugin, this means that I don't need a Unity MCP - Because Bezi is built for Unity, the success rate of feature implementations is visibly higher than general coding models - It was able to integrate Unity store assets like a Weather system to this game pretty seamlessly - I was able to add a fishing database, lighting and weather systems into this game fairly quickly I'm very impressed with the results with Bezi so far. I feel that vibe coding a full indie game on Unity and releasing it on Steam, Mobile and Web is within reach. This also validates one thing that I have been suspecting: A specialised model designed for a specific use case can perform better than a general model at the particular domain. Very exciting!

this is f**king dangerous someone just figured out how to get fable 5 reasoning in opus 4.8 with one prompt you have less than 24 hours to set this up as this takes away 20% of your usage limit here is how: 1) Paste the prompt and ask it to "make an operating manual" 2) Create a New Claude Project and "Add this .md in Project instructions 3) Use Opus 4.8 High/Max and now you have Fable 5 reasoning at 1/5th the price save and bookmark it no matter what

Opus 5 is a BEAST. I tried Matt Shumer's viral prompt and it actually one shot a real FPS zombies style game. I tried something similar with Fable and Kimi K3 and it never got anywhere close to this. This cost me almost $400 in tokens and took about 3 hours.

I'm playing around with generative AI tools and stitching them together into visual stories. Here I took the first few sentences of Pride and Prejudice and made it into a video. The gen stack used for this one: - Anthropic Claude took the first chapter, generated the scenes and the individual prompts to to the image generator. - Ideogram took the prompts and generate the images - Luma took the images and animated them - for narration - VEED | AI Video Creation to stitch it together (Many of these choices are just what I happened to use for this one while exploring a bunch of things). Anyway honestly it was pretty messy and there is a ton of copy pasting between all of the tools, and even this little video with 3 scenes took me about an hour. There is a huge storytelling opportunity here for whoever can make this convenient. Who is building the first 100% AI-native movie maker?

Wow. I just put a formula together for the video generator agent and it just output this, really interesting: Running a few more tests before I implement properly. Remember, it's creating the entire logline, prompts, clips - everything by itself AND editing the clips together. Currently in the Replit app, I tweaked the app so that you could see each individual scene in addition to the final video and have the prompt for the scene. However, that makes waiting like 15-20 minutes as opposed to like, 6-8 minutes. Thoughts? Do you all want to wait longer for your prompts at first to try this thing out? I'm getting ready to push soon, there's just a few bugs.

Fable 5 just turned me into an iOS developer. I spent 2 days building a full game with zero code written by hand. The last 10 builds succeeded on the first try. I needed a fun project to test it on, so I decided to make an iOS game. After a few experiments with other ideas, I settled on a runner starring Dario as the main character, called "Credit Runner". Hilarious, I know! In terms of credits spent, my Claude Max plan stands at 36% right now, and this isn't the only project I ran through Fable 5. A few quick notes: - This is just an early prototype, a long way from release, but it's really fun to play! - It's extremely fun to work with Fable 5! - Fable 5 wants to get things done, and it pushes you towards completion much faster than any other model. - Once we established the ground rules, how I wanted the game built, and the overall structure, the last 10 builds were flawless, succeeding on the first try. This is impressive! - All the assets were generated with AI (Magnific and Trippo for the visuals, ElevenLabs for the voices). The only thing that's not AI is the music. I just really liked this track. - There are many rules in the game designed to make it really fun to play, especially the randomness. - There are a lot of visual cues inspired by San Francisco, and I hope you catch them all. - At some point on the first day, I honestly thought I wasn't going to get where I wanted, but Fable pushed me towards the goal, and by the second day it started to deeply understand the project. - The prompts were really long, especially in the beginning, to make sure everything was covered. - Once the app was solid, I tried to pack as many changes as I could into a single prompt to maximize my Fable usage. This was just a fun project, but if anyone wants to play it, I might put the final, much more polished version on the App Store. What do you think? Should I?

Mixtape is the first game; I didn't have to play to play it. It's colorful, it looks great, but I really ain't playing the game at all... This is probably gonna be the WORST game imma play this year FREE YOU LITERALLY DO NOTHING, and even the button prompts they do give you have no errors or fails. I don't get where the 10/10 is coming from, where most of the interaction is hitting the start button for the first time
