Probably would have costed brain dead astra $900 to create something on the same level that Opus 5.5 did. To my eye Opus is SIGNIFICANTLY cheaper for the level of quality that it produced. Astra literally sniffing glue in the corner

Opus 5 has that taste, that sadly gpt models still don't.

Only 23% more for 53% longer. Opus was cheaper per minute.

it is cheaper i agreee

This is a useful outcome split: Opus 5.5 bought more detail with 2h10m and $75, while Astra finished in 1h25m at $61. The next experiment should report acceptance rate, retries, and human edits so “better” includes quality and iteration cost.

Opus added more details

MT1 day ago

way more?? its not that uch more

Inkmitsu1 day ago

same prompt, same harness, max settings — the honest comparison format

K2S1 day ago

I feel opus did better if we see the quality

Hustle Lab1 day ago

the detail thing tracks — opus is the friend who proofreads the group chat, astra's the one who replies 'sure' in two seconds. both have their uses honestly

This looks like a video of the Golden Gate Bridge, but it's actually entirely generated using code by Claude Opus 5.5. From my testing, I think Opus is just as good at building 3D scenes as Astra. 📌 Watch my latest video to see how Opus and Astra compare on this scene and more:

I asked Astra (GPT-6) and Fable 5.1 both to build GTA VI like game researching about it, and the results are below. Same prompt. Fable took ~2 hours; Astra took ~90 minutes. Watch the full gameplay side by side below, with audio switching every 10 seconds

Asked opus 5.5 to make a video of openai solving Navier-Stokes. Very nice model, I still prefer Astra and 5.6 as my main drivers as I do a lot of research heavy work but 5.5 Opus is the first time since 4.7 that I want to heavily run Claude. It has great taste.

Opus 4.8 vs GLM 5.2 everyone is praising Glm on my timeline, so i had to test it myself > both models were given the same prompt > GLM was super fast and used like 2% of my weekly limit > Opus took over 20 mins and used like 3% of weekly limits which one do you think won?

Same prompt. GPT-5.6 Sol vs Opus 5. All in Three.js. Opus produced the better raw visuals. The ocean, waves and atmosphere look noticeably richer. But it also: → cost ~10x more → took much longer → needed an extra prompt just to fix the camera controls Sol got surprisingly close on the first attempt, much faster and far cheaper. Opus wins visual fidelity. Sol wins the actual engineering test.

I recreated Townscaper with GPT-6 Astra using Three.js on Happycapy The result is surprisingly close to the original, and it took way less time than I expected 🤯 Astra is seriously good at this kind of 3D coding task.

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

Day 3 of getting back to building my gamified workout tracker. (have some AI features) I just tested both Opus 4.8 and GPT-5.5 for the multilingual feature, and Opus 4.8 is still slightly better. It only needed one prompt to solve it. My apps always supports multiple languages because I target multiple markets and don’t want to depend on just one market. Powered by Opus 4.8, Rork, Cursor

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 5 before, and it never got this level of realism in one shot. If this is actually Opus 5.2, it could be a game-changing model for Anthropic. I’m starting to think Opus 5.2 could mog Astra in frontend and 3D.

The upcoming new Opus model is exceptional at 3D tasks, particularly in environments like Roblox Studio. It outperforms both Fable 5.1 and 6 Astra at a lower cost, and is faster. Here's an example that blew me away. The game is fully explorable, and Opus added this tour. It didn't even finish as I had to cut it off (it had been switched back to old Opus and I didn't want any work ruined).

deepseek v4.1 flash vs secret model tested both with the same prompt at the highest reasoning available > v4.1 flash took 2 hours to finish both tests and cost $2.60 > secret model finished both in 30 minutes, can’t reveal cost yet v4.1 flash spent a lot of time overthinking and running random tests, which slowed it down thanks AIHubmix for providing api access so i could test v4.1 flash hoping that team will cut down the overthinking before the full release, but for now here are the results which model did better here?

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?
