GPT 6 Astra one shotted a bug in BridgeMind that no model could solve in 6 months. Fable 5 failed. Fable 5.1 failed. Opus 5, Sol, Grok 4.6, all failed. Astra fixed it on the first prompt. Then it rebuilt my office in Blender from photos. Built a racing... show more

one-shotted a bug six models failed at while using a third of the tokens is either the most important benchmark result of the year or a cherry-picked task. You know , i am really super curious which it is across 100 tasks ?

It remains to be seen whether posts like these reveal something important about Astra’s capabilities. It may just be that Astra happened to better at that one particular problem.

I think this is the part where AI enters a phase of actual useability in the real world more widely than just apps. I 100% agree that this will be remembered at the beginning if AGI 10 years from now.

DO IT WELL NOW22 days ago

Here's the important part though. This is one person's opinion after using the tool himself, not something proven by outside testing. People online often say big exciting things like this to get attention and views, especially when a new AI model just came out, since that is when everyone is curious about it.

Serdar Doğrubakar22 days ago

These models are great for one-shot miracles and very specific problems. For continuous use and actually building a project? They’re all fucking terrible. They drink tokens like water. Astra included. I don’t care how smart a model is if a few hours of real work burns through a weekly quota. That’s not productivity. That’s a demo.

Gregor22 days ago

Genuinely curious about the '6 months, first prompt' combination. Was the prompt you gave Astra identical to what you gave the others, or had six months of failures changed how you described the problem?

Chestuits22 days ago

The bug fix and Blender rebuild test very different kinds of work Together, they make the review less dependent on a single benchmark

Jatin Garg22 days ago

Six months of failing means you've basically given Astra a perfect bug report. Still impressive, I'd just want to see it one-shot a bug you found five minutes ago.

Someone gave GPT-6 and Fable 5.1 access to Canva. One smoked the other (it's not even close). Claude Fable 5.1 is on the left. GPT-6 Astra is on the right. The gap is not small. It comes down to one test (ARC-AGI 3). It drops a model into a game with no instructions and makes it work them out. Astra solved levels in fewer moves than you or I would, 96% of the time. Claude Opus 5 managed less than half of that. That's why everyone is shouting about AGI again. You can turn this on yourself in about two minutes: 1. Open the ChatGPT desktop app, switch to Work. 2. Go to Plugins, then Computer Use. Install it. 3. Switch on the server and skill toggles. 4. Allow Screen Recording and Accessibility. 5. Point it at one app and ask it do something. I wrote up the full Claude → Codex migration. Access it here → Repost ♻️ to help someone in your network.

One shot prompt with no loops: GPT-Sol Ultra: 35,192,545 tokens used Opus 5.0 Ultracode: 1,171,676,041 tokens used Fable 5.1 Ultracode: 127,366,207 tokensused Same prompt… different results: Fable 5.1 runs at 5fps so I had to speed it up to demonstrate the rendering. Would need further optimisation. Opus 5.0 runs very nicely on first prompt. Doesn't need much in terms of performance optimisation. Just a few odd visual things here and there. My verdict: Fable looks impressive but struggles to run smoothly. Opus is a solid model when prompted properly. Sol is garbage.

New Fable 5.1 absolutely crushed Fable 5 at making a racing game👾🔥 Claude just dropped Fable 5.1, so we gave both models the same prompt to build a playable racing game from scratch in Godot with BlenderMCP Tasks: - Make car and environment models using BlenderMCP - A big map for long driving sessions - Realistic car handling - Simple HUD for speed and controls Outputs: Fable 5.1: 1.2M tokens, 123.98$, 59.8 minutes Fable 5: 897K tokens, 95.87, 57.3 minutes Fable 5.1's models are far more detailed and the game runs smooth, the world feels alive while you drive. Fable 5 finished all three tasks and its HUD and controls work, but its models are plain and the game feels stiff

Claude Fable 5 makes new things possible. I one shot a full horror game with it. One prompt. I have never seen AI output a game like this. This is the leap I've been waiting for. 80.3 on SWE-Bench Pro vs Opus 4.8 at 69.2, the biggest jump I have ever seen on that benchmark. It passed GPT 5.5 in both coding and intelligence on Artificial Analysis. I already canceled my $200 ChatGPT Pro plan. It fixed a Bridge Voice bug in one shot that GPT 5.5, Opus 4.7, and Opus 4.8 all failed to crack for 2 months. 10/10. Best model I have ever used. Full review below.

Fable 5.1 is an absolute beast for game dev. I took my Opus 5 space game and told Fable to "just make it look better". It overhauled everything with a TON of detail, AND made it 2x faster 🤯 Code: Demo: Every pixel you see is made by AI. Fable modeled everything in Blender, generated textures with code, and in a few cases ran image models via CLI. In mere months we'll be vibe-coding AAA graphics at this rate. Just insane. Of course, Fable recorded and edited this comparison video too (with a little help from Opus at the end, because of the Fable outage)

Something feels seriously off with Claude Fable 5.1 🙄 I recreated the exact same 3D stadium I had built with Fable 5 just to see how much better 5.1 would be. Instead, Fable 5.1 took more than > 1 hour and hit the max limit 2 or 3 times on a single prompt. Fable 5 basically had the whole website ready in one shot and its output was actually much better. Fable 5.1 felt good with metal but added these weird black things that look like basket wings... genuinely have no idea what those are. Not good. And this observation isn’t just for one website. I saw similar behavior with a much simpler hero page where Fable 5.1 maxed out on a single prompt, something I never really experienced with Fable 5 for similar other websites Also, 3D models and animations of that other website also looked noticeably worse compared to what Fable 5 used to produce. In fact, they were even worse than what I’ve seen Opus 5 do. I’ll keep testing it, but so far Fable 5.1 feels less like an upgrade and more like a regression to me, tbh.
