GPT-6 Astra & File Cleanup Turned Into Tinder

What people are building with GPT-6 Astra, how it stacks up against Fable 5.1, whether AGI is really here, and swipe-clean: a free skill that turns messy workspace cleanup into swipeable cards.

the short answer

GPT-6 Astra beat Claude Fable 5.1 in side-by-side builds like one-prompt Minecraft, Unreal Engine scenes, and fully AI-generated video, but it is not AGI: benchmark wins are not the same as beating humans at most economically valuable work. The post also shares swipe-clean, a free skill that turns workspace cleanup into swipeable review cards.

key takeaways

  • In community comparisons, GPT-6 Astra produced more detailed games, 3D scenes, and video than Fable 5.1.
  • AI-generated video now looks human on mute, but default voices still sound monotone and robotic.
  • Astra scored 99.9% on ARC-AGI-3, but benchmarks and tool-dependent abilities do not meet OpenAI's own AGI definition.
  • swipe-clean scans folders, files, memory, and instructions and lets you swipe to delete, keep, archive, or fix without touching anything first.

It seems like every day a new "revolutionary" model comes out that beats the competition on some obscure metric. So let's cut the fluff: here's the coolest stuff people have already built with OpenAI's GPT-6 Astra, whether Claude Fable 5.1 can keep up, whether AGI is actually here, and a cleanup skill I built that's one of the most useful things I've ever made.

1. One-prompt Minecraft

Someone claims they built a working Minecraft clone with Astra in one prompt. Even if it took a few, this is mental. Someone tried the same thing with Fable when it came out, and Astra's version is noticeably more detailed, with better gameplay mechanics and more NPCs.

Astra takes the cake easily here.

2. All of Manhattan, street by street, in Unreal Engine

I saw someone build the whole of Manhattan in Unreal Engine with Astra in less than a week. I couldn't find anyone who recreated Manhattan with Fable, but in a side-by-side comparison of a villa generated by both, it wasn't close.

Need I say more? Astra: 2, Fable: 0.

3. A full YouTube video generated by Astra

Watch the full AI-generated video

This one really impressed me. AI video has always looked good but had noticeable patterns. Here, Nate's avatar looks exactly like him, and the editing looks like a professional did it. If you watched it on mute, there's genuinely no way you could tell it was AI.

The audio has the same flaw as other AI-generated videos, though: a monotone, robotic-sounding voice. Plugging in the ElevenLabs or Fish Audio API would have made it sound a lot more natural, but it's still a flaw.

I've tried editing my reels with Fable, even using skills like Remotion, and it doesn't come close to what I saw in this video. Astra for the win again.

Is AGI really here?

That's what Nvidia CEO Jensen Huang claimed after Astra's release, but I beg to differ.

Even OpenAI's own president, Greg Brockman, didn't go that far. He said it's "not unreasonable to feel" we're in the AGI era, which is a very different sentence from "AGI has arrived."

OpenAI's own definition of AGI is "a system that beats humans at most economically valuable work." Astra hasn't shown that. What it has shown is 99.9% on a benchmark called ARC-AGI-3 and a perfect score on a cybersecurity exploit test.

Impressive, but benchmarks aren't the same as "does your job better than you." And a lot of Astra's flashiest abilities (computer use, tool use) depend on the tools and permissions you give it, not the raw model.

So no, I don't think AGI is here. Astra is a genuinely huge leap in capability, and "AGI era" is a great marketing line to say two days after a launch when Nvidia has a direct financial interest in everyone buying more GPUs.


This week's build: workspace cleanup turned into Tinder

This one's for all my vibecoders. Working with multiple agents, folders, and projects, you accumulate a lot of junk very easily.

Every time I ask Claude to update the MD file, it just writes over everything and doesn't check for contradictions, duplicates, or pretty much anything. Give it a month of vibecoding and your setup looks like a crime scene.

So I built a skill called /swipe-clean.

It scans your folders, files, memory, and instructions, and turns every problem it finds into something you can review without touching or deleting a single thing first. Full diagnosis, zero risk.

Then it turns them into cards you swipe:

  • Left to delete
  • Right to keep
  • Up to archive
  • Down to move or fix

It turned boring maintenance into a queue of quick decisions I can actually finish.

frequently asked

Is GPT-6 Astra AGI?[+]

No. OpenAI defines AGI as a system that beats humans at most economically valuable work. Astra's strong benchmark scores and tool-use demos do not show that, and even OpenAI's president only said it is 'not unreasonable to feel' we are in the AGI era.

Is GPT-6 Astra better than Claude Fable 5.1?[+]

In the comparisons covered here (a one-prompt Minecraft clone, an Unreal Engine villa, and an AI-generated YouTube video), Astra produced noticeably better results than Fable 5.1.

What does the swipe-clean skill do?[+]

It scans your project folders, files, memory, and instruction files for problems, then shows each one as a card you swipe left to delete, right to keep, up to archive, or down to move or fix. Nothing is changed until you decide.
