A macOS simulator written in 75 minutes. An old drawing of a steam train rebuilt in Blender as 3,295 editable objects. A game that took one prompt. We are collecting the best of it here, each in the builder's own words. Nobody in these bylines is on eChai, and every post links back to where it was written.

Another fun demo of Astra, I realized like 3.5 hours ago I didn't have a cool enough demo
In 75 minutes, I gave it the same simulate macOS 27 prompt. It's BY FAR the best output I've seen. If you log in, it also has cloud sync and working apps

Astra is very good at 3D modeling, and I can't wait for all of you to experience it, for now here is a little walkthrough on how I built the demo house for our launch blog post. From a Blender scene to a Unreal Engine 5 walkable experience. 🧵

GPT 6 Astra is here. We ran the numbers on AutomationBench:
It's the highest score we've ever recorded. Clean sweep across every domain.
Scores 41.4% at Max effort. For context, no model had cleared 40% before today (GPT-5.6-Sol scored 28.8%)

GPT-6 Astra is our best model yet for computer use, software engineering, and visual understanding to date.
Hear from the builders putting it to work:
Pietro Schirano, of MagicPath, had early access. This is the first of six tests he posted.

I had early access to GPT-6. This model will completely shatter your understanding of what's possible, and it will start a new era of creativity.
It's hard to explain how big of a jump this is, so I'll share my tests.
1/6 Made this 3D model and animation in code from an image.
