Opus 5 (before) vs Opus 5 (now) I tested this rocket scene again after people started saying Opus 5 might be getting routed to Opus 5.2. And yeah, the difference is pretty clear. I know these models aren't deterministic, but I ran the same scene multiple times with Opus... show more

i believe that too openai models are weak in frontend design

but not on 3d part 🤪

Anthropic just raised the bar the frontend + 3D jump looks serious

Upgrade?

I don’t know if it’s Opus 5.2, but there’s definitely a noticeable improvement in performance.

I've noticed the same thing with other scenes. Performance seems way improved.

Idk, both are really good, i couldn’t pick a side here

Huge difference

And if they're correct, what makes you think they won't switch back again nothing like having to wonder on a day-to-day basis whether you're being deceived.

how opus 5 get so much better now?

Yeah, openAI models are weak jn frontend designs

Haleemah1 day ago

You think it’s routing for you ?

Axi1 day ago

Practically no difference

John Kler1 day ago

Opus 5.2 will likely be better than Astra at frontend. I'm not so sure about 3D though. It will definitely be way cheaper.

Opus 5.2 is COOK-ING

Malou | MMM1 day ago

did you rerun the old prompt twice before comparing? i get different output on identical input often enough that one run per side wouldn't convince me.

Kevin Reutter1 day ago

Can confirm this is true. For games and for apps.

J A Z I I1 day ago

a big difference indeed for sure routing

ForeverPatriotic1 day ago

If we’re being honest. I think these models might be mixture of expert, and have different thinking/juice or even quantization. So we get closer to the full at launch and then they back it off. If this Op. 5.2 is a fable derived then yes

Tony1 day ago

The panel details on the rocket look sharp. I’d be happy getting that in one shot.

anthropic cooked hard with opus 5.2 after testing it for a whole day, i can say this model is so good > huge step up from opus 5 > on par with astra > faster than opus 5 > way better at frontend and 3d here’s one frontend test i ran and it’s the best output any model has given me even better than astra you can check fable 5.1 output with same prompt in QT and tbh opus 5.2 just mogs everyone here really hoping that anthropic will release this model officially this week

opus 5 is getting routed to opus 5.2 tested opus 5 on xhigh with the same prompt in devin and claude code but results came out really different > claude code one is clean and more detailed > while devin one is almost there but not the same opus 5 in cc used to be lazy and hard to communicate with, but something changed in the last 2 days now it works for longer and is way easier to communicate with anthropic did same with fable release too where some users were being routed to fable 5.1 so it’s very likely opus 5 is getting routed to 5.2 in claude code can you guys tests and lemme know if it's getting routed for you or not?

Gemini 3.8 Flash vs Opus 5 same prompt to each model and i wasn't expecting gemini 3.8 flash to be this fast! build time: > Opus 5: 24 minutes > 3.8 Flash: 37 seconds 💀 if gemini is given same time as opus 5 it will mog the hell out of opus in terms of quality too which one would you choose here?

i tried Opus 5.0 vs Fable 5 Max. Claude Opus 5.0 is quite the AGI beast in 3D, the texture and details are absolutely insane. Fable one shotted this though, could be improved. credit to Chetaslua for the Opus 5 code.

Grok 4.5 operates at Opus-level intelligence and Sonnet-level pricing! We tested it against Claude Opus 4.8, Sonnet 5, and GLM 5.2 on a SpaceX mission: liftoff, stage sep, orbit insertion, satellite deploy. Grok 4.5 animates it more accurately and vividly than Sonnet 5 and GLM 5.2. Opus is the fastest and most expensive. Grok burns more tokens but still lands ~40% cheaper than Opus, and a bit under Sonnet 5. Time / tokens / cost: Grok 4.5 — / 35k / $0.69 Opus 4.8 — / 13.7k / $1.10 Sonnet 5 — / 22.1k / $0.78 GLM 5.2 — / 92.7k / $0.13 yet GLM did the whole mission for $0.13 😮

OPUS 4.6 WAS NERFED DUE TO DEMAND BUT OPUS 4.5 DOES NOT SEEM TO BE HIT this guy ran the same test on both models. Opus 4.6 fails consistently but Opus 4.5 passes every time he switched back to Opus 4.5 on Claude Code and said "what a difference, feels like i got Opus back finally" he is now using this test as a "quantization canary" that runs it at the start of every session before doing real work. if it fails, the model is degraded. five Opus 4.6 windows in a row failed the untransparent nerfing is pushing people to cancel their Max plans if you've been feeling like Opus got dumber lately, you're not imagining it i'd suggest switching to Opus 4.5 to see the difference for yourself

Claude Opus 5 just made the best Remotion video I have ever seen. Perfect transitions. Music timing locked to the frame. Branding nailed without me asking. Fable 5 held this crown for months. Opus 5 took it in one prompt. Opus 5 significantly outperforms Fable 5 at marketing videos, and it is not close. Watch this and remember Opus 5 made it.

I was skeptical about giving GLM-5.2 the task to build a super mario snes style game in a single HTML file so i ran the test on Opus and also on GLM-5.2 Opus didnt even try to make a game or made something but it wasn't a game GLM-5.2 one shotted a pretty functional game.. WILD

i gave the exact same prompt to Opus 5 and Fable 5 and here's what came out Opus 5 dropped yesterday and my feed was instantly full of comparison posts but i wanted to check it myself so i gave it one task build 3d Flappy Bird first thing everyone was saying Opus is 2x cheaper than Fable BUT.. building the game on Max effort cost me 250k tokens and 1 hour on Opus and 130k on Fable but Fable did it in half the time Opus gave me volume control plus 3 separate graphics presets to choose from, Fable gave none of that in Opus the environment shifts dynamically as you play in Fable it's basically the same frame the whole run maybe a day/night change here and there graphics, animations, glow, all of it goes to Opus and now that limits jumped 50% for the near future while Fable went paid for me the call is obvious right now Opus same prompt start to finish zero changes to code or commands want it? i can send it over

I applied Matt's prompt, ran it for a little over ten hours. About 1.3 million tokens on Opus 5. It created the game. I also made a video of it using Opus 5. Here's the video (and in my reply to this is a link to the actual game so you can play).

Opus 5 High might be the most ridiculous model I’ve ever tested. It produced this result in around ONE HOUR. Fable 5 needed almost 3 hours. GPT-5.6 Sol worked for over an hour and still created almost nothing compared to this. Opus 5 didn’t just win. It completely OUTCLASSED them.

Anthropic finally published the prompting playbook for every Claude model. > Prompting Claude Sonnet 5. > Prompting Claude Opus 4.8. > Prompting Claude Opus 5. > Prompting Claude Fable 5. After reading it, one thing is clear. Almost nobody is getting the most out of Claude. It shows exactly how each model should be prompted instead of relying on guesswork. If Claude is in your workflow, bookmark this.

I used Opus 5 with the Unity CLI and Gauntlet Loop to see how well it could build games within Unity. While reviews are mixed on Opus 5 for coding and tasks in general - I think it's a huge unlock for gamedevs. It's understanding of 3D space + ability to self critique is actually one of the most important breakthroughs. 00:00 Intro 02:55 Unity CLI 04:38 Spriterrific 06:40 Unity + Opus 5 08:20 Gauntlet Loop 09:38 Demo 12:21 Wrap Up

Are AI agents shape rotators? In this new benchmark, we let the models play campaign puzzles in Opus Magnum, a puzzle game by Zachtronics. Ironically, Claude Opus 4.8 performed poorly, being beaten by GPT-5.5, Gemini 3.5 Flash, and GLM 5.2. Claude Fable 5 crushed them all.

They did it. Claude Opus 5 is BETTER than Fable 5 and half the price It's the smartest model ever made Plus you can actually use it without draining your bank account In this video I cover the best use cases for Opus, when I still use Fable, and where GPT 5.6 still wins:
