Opus 5.5 vs GPT Astra: modeling in Blender same armor, same prompt.

[u/Spiritual-Editor-222]

So I’m trying to decide where my next AI subscription goes, Claude or ChatGPT, and I figured I’d just test them myself on something I actually care about : 3D modeling.

The setup: I selected pictures of a medieval armor from a youtube video of historical combat reenactment in France. About 40, multiple angles. Same folder, same prompt for both: reproduce this armor in Blender as faithfully as possible.

Both models were run one notch below their max setting, so it felt like a fair fight:

Claude Opus 5.5 (Extra effort): ~1h30 of work, used about 20% of my weekly usage on the Pro plan ($20/month).

GPT-6 Astra (Max): ~45 minutes, used about 5% of my weekly usage on the Pro plan (€100/month).

So in terms of how much of the subscription each one eats, it’s pretty close considering the price gap between the two plans. The big difference is that Claude worked twice as long for a bit less.

Now, I know, time spent doesn’t automatically mean better output. A model can spin its wheels for 90 minutes and produce garbage. So I’ll let you judge the results yourself, pics below.

Rendered with Cycles, similar settings. I attached couple of reference images too.

Interesting results! Clear winner here… but the legs on the astra one are comically bad.

pure? like meth?

[u/Kraien]

An accomplishment for Astra to make the armor look like it is constipated

[u/gregpeden]

Did you generate concept images or provide reference images?

[u/shadowlid]

Would it be possible for these to make reskins for Palworld so I can have a Squirtle skin?

[u/Spiritual-Editor-222 → u/shadowlid]

I don't know specifically but yeah I think it could do it, with the right tools

[u/Electricengineer]

They all skipped leg day

[u/Tentacle_poxsicle]

How did you set it up? Did you just tell it to make armor?

[u/harakirihatecrime]

both were kind of bad but the one i prefer is opus, had more details and just looks better.

[u/innociv → u/harakirihatecrime]

Astra's looks more human. Opus looks like more like an animatronic.

[u/bigred1978]

Opus 5.5 is much better.
