The Opus 5.5 nerf debate just got receipts.
on launch day, a dev had Opus 5.5 one-shot a remake of Lander, the classic Acorn Archimedes 3D game by Elite creator David Braben. he saved the exact prompt and reference images, then ran them again 9 days later.
what he says got worse:
* rendering → props now snag and glitch as the camera moves
* physics → the ship no longer breaks apart on crash
* the menu → the intro controls screen is gone
* bullets → spawn at the back of the craft and clip through things
* camera → no more camera toggles
his setup:
→ same prompt, same reference images, a fresh workspace
→ Opus on Extra High effort both times
→ he says the gap is too big to blame on randomness

🚨 Anthropic may have NERFED Opus 5.5 BIG TIME.
I'm seeing a wave of reports that Opus 5.5 suddenly feels VERY different:
→ Dropping tasks
→ Skipping commits
→ Claiming work is done when it isn’t
→ Losing task focus
→ Reasoning feeling noticeably weaker
And there’s already a GitHub report documenting serious task-focus regression.
Nerf? Routing issue? Something else?
Way too early to say.
But this is getting harder to ignore.
Opus 5.5 was supposed to be one of Anthropic’s biggest weapons.
If this keeps spreading, Anthropic has a VERY different problem on its hands. 👀

I honestly wouldn’t be surprised if they’re nerfing Opus 5.5 to set up the Fable 5.5 launch for next week.
That’s very Anthropic, and I’ve already seen them nerf models in public before and then say it happened by accident.

Claude Opus 5.5 just took a big drop on NerfBench.
Yesterday it was scoring above launch. Today it's at 94.2%.
GPT 6 Astra: 98.0%
Sonnet 5.5: 100.9%
GPT 6.1 Sol: 106.7%
94.2% is still inside normal variance, so we can't call it a nerf yet.
But we're watching Opus 5.5 very closely.

A lot of people are saying Anthropic has already nerfed Claude Opus 5.5.
We're launching NerfBench on BridgeBench tomorrow.
We have the day 1 results.
Tomorrow morning we show you the retest.
Is Claude Opus 5.5 nerfed or not?

OpenAI just gave us a reset AND addressed every GPT 6 Astra nerfing complaint in one post.
Found the bugs, named them, fixed them, explained what happened, thanked the community.
Anthropic would have gone silent for three weeks and then gaslit you about cost efficiency.
This is why people root for OpenAI right now.
Hi Astra users. A reset and a quick update on quality issues that have been posted around.
Working with some of you, we have found and fixed the following issues:
- Some skills written for previous models were triggering too often or preventing the model from checking its work.
- An opt-in context management experiment that could cause early stops or replies to older messages. We've disabled it. Our rough estimate is that 4-5k users were affected by this experiment.
- We've also removed some badly configured engines that resulted in a measured quality degradation for a long tail of traffic flowing through them.
We’ve also made some more minor improvements and things should feel significantly better across the board. More consistent follow-through, better tracking of your latest message, and better checks on the work as it’s going through the motions.
The examples posted and all the users who worked directly with us were incredibly useful in helping fix things quickly. Always grateful for this incredible community.
And of course, a reset is also landing by midnight today.

It is over for Anthropic.
GPT 6 Astra beats Fable 5.1 in speed, cost, intelligence, backend, one shot, and debugging.
Fable 5.1 still wins design. That is it.
Fable 5.1 is the best design model in the world.
GPT 6 Astra is the best overall model in the world.
