I feel unstoppable with Opus 5.5.
I'm shipping 2x what I was before.
It's hard to imagine AI getting better than this.
But Fable 5.5 is going to be a massive jump over Opus 5.5, and I don't think any of us are ready.

Gemini 4 Argon is a solid improvement for Google.
But it comes nowhere near Claude Opus 5.5.
Disappointed that Google is still this far behind.
Gemini 4 Argon JUST DROPPED in the Antigravity CLI.
Is Google back???
Muse Wonder is benchmaxxed.
Meta says it beats the competition on the key benchmarks. On the BridgeBench lava lamp test it built a red cylinder.
No glass. No lava.
I've never seen a model this benchmaxxed in my life.

Latest NerfBench results are in. No nerfs detected.
Claude Opus 5.5: 95.7%
GPT 6 Astra: 102.0%
Claude Sonnet 5.5: 103.1%
GPT 6.1 Sol: 105.5%
All four are within normal variance.
But Opus 5.5 is the one to watch. It's the only model below its launch score.
We'll keep testing.

I still have not used Fable 5.1 a single time since Opus 5.5 dropped.
Fable 5.5 is about to change that.
Claude Haiku 5.5 just dropped and it completely fails the BridgeBench lava lamp test.
No glass. No lava. Just a yellow cylinder.
GPT 6 Luna built an actual lava lamp in 42.8 seconds for under a penny.
Haiku took 4m 34s and cost $0.03.
GPT 6 Luna is over 6x faster and 3x cheaper.

I just cancelled 1 of my 4 Claude Max subscriptions.
Not because I don't like Opus 5.5. It's the best model I've ever used.
I cancelled because the usage is so good that I don't need 4 anymore.
OpenAI has to keep resetting limits to stop people from leaving. With Anthropic, great usage just comes with the subscription.

Mistral Large 4 just lost to DeepSeek V4.1 Flash.
Same sunset ocean prompt. Mistral rendered a blank screen. DeepSeek nailed it for 3 cents.
Claude Opus 5.5 and GPT 6 Astra built the best scenes of the four. Astra did it 3 minutes faster and for 30 cents less.
Europe's flagship model can't beat a Chinese flash model.

Mistral Large 4 just dropped and it completely fails the BridgeBench lava lamp test.
No lamp. No lava. Just a blown out light.
It is cheap though. $0.02 for the whole run.
GPT 6.1 Sol built a working lava lamp for $0.09.

I'm more curious than excited about Gemini 4 Argon.
I tried Gemini this morning and it was honestly shocking. I could barely have an intelligent conversation with it. After using Opus 5.5 and GPT 6 Astra every day, it's by far the dumbest AI I've ever used.
Google says Argon leads 12 of 18 benchmarks. I'm paying for Google AI Ultra and still can't use it.
I really hope it's good. Google needs it.

OpenAI has to keep resetting usage and shipping improvements over the next 28 days for one reason.
To stop everyone from unsubscribing.
The models aren't good enough and the usage is horrible, so they're buying time with resets and patches.
Why not just focus on shipping a good model with good usage?

China has fallen behind in the AI race.
In July, Kimi K3 was supposed to be China's answer to American AI.
Today it couldn't even render a lava lamp.
Claude Sonnet 5.5 and GPT 6.1 Sol nailed it. Those are America's mid tier models.
Right now, China can't keep up with America's second best.

Anthropic gives their users way more compute than OpenAI.
GPT 6 Astra is practically unusable on a Codex subscription. I burn through my entire weekly limit on the $500 plan in a day.
GPT 6.1 Sol gives you a lot more usage. But Opus 5.5 is leagues ahead of it, and Anthropic's subscription still gives you way more.
Anthropic gives you a smarter model with more usage.
It is not even close right now.

No one has done more damage to OpenAI than OpenAI.
A month ago GPT 6 Astra had them way out in front.
Then they:
1. Cut Astra usage in half on DevDay
2. Pulled the usage numbers off the Pro plans
3. Rushed out 6.1 Sol one week after 6 Sol
4. Promised a global reset that didn't show up when they said it would.
Meanwhile Anthropic shipped Opus 5.5 and raised limits. It's at 58 on Artificial Analysis. Astra is at 53.
OpenAI had the lead and fumbled it.
Fable 5.5 is going to be the nail in the coffin.

Anthropic has done serious damage to OpenAI.
Opus 5.5 is insanely intelligent and affordable. GPT 6 Astra is less intelligent and costs 2.5x more.
And Fable 5.5 is dropping soon.
Even if GPT 6.1 Astra drops tomorrow, it's going to be hard to win me back.
A better model doesn't matter when your weekly limit runs out in a day.

Is Claude Opus 5.5 Nerfed?
I Built NerfBench to Find Out.
@theo, it's very clear you're jealous of BridgeMind.
Some of your questions were fair. I'll be sharing more on the NerfBench methodology soon.
But asking me to take NerfBench down and post an apology written by you isn't about better benchmarks.
It's about your ego, and not wanting anyone else to exist in this space.
More benches are good for everyone. Build yours.

The OpenAI situation keeps getting worse.
Yesterday Tibo announced a global reset for all paid ChatGPT accounts at 10am PST today. It's been over 2 hours. No reset.
Builders literally scheduled their whole day around this.
First they cut usage in half.
Now they promise a reset that doesn't show up.
You can't keep doing this to the people paying you.

Claude Opus 5.5 completely changes what is possible.
Work that used to take me 2 weeks now takes me 2 hours. I still can't wrap my head around that.
It's Fable 5.1 level intelligence at $4 in and $20 out, it's faster than Opus 5, and the limits finally let me use it all day. No model has ever given me all three at once.
The world is changing so fast and most people have no idea yet.
