- Interesting. I’m building a SaaS around this idea. And I managed to do things waaay more complex than that using LLMs. Especially “several times”. My AI can do a parametric trophy cup from one prompt in a couple of attempts, I would be shocked if it didn’t know how to make rectangular cube…
- There was quite a bit of interest in the 3D modeling data when Gemini 3 was released[0]. So I have decided to write about my findings.
It's the first time ever I am submitting a link to my AI 3D Modeling software (even if it's just a blog post), so I would appreciate any feedback - or request for other data you may want to see.
- Thanks for clarifying. I'm just getting into this field.
If Blender can export a .3mf file format and slicer gets it ready for 3D printing (gcode that actually instructs the printer head). Is the slicer actually CAD software?
And if you can export many formats that work with some manufacturing devices and you built a model in blender, did blender not help you with CAD?
- Computer aided design. Tree.js can be CAD. But I agree it’s not meant for CAD even though you can do it.
- Based on my benchmarks (run 100s of model generations).
2.5 stands between GPT-5 and GPT-5.1, where GPT-5 is the best of the 3.
In preliminary evals Gemini 3 seems to be way better than all, but I will know when I run extended benchmarks tonight.
- I started with a lighter weight solution (JSCAD) first and quickly hit the limitations. So I wanted to explore the other side of it - fully complex over the top software (blender).
I guess openscad would be a sweet spot in the middle. Good shout, might experiment.
- Yes. I’ve been working and refining the prompt for some time now (months). It’s about 10k tokens now.
- It’s not a format, but in my mind it implies designs that are supposed to be functional as opposed to models that are meant for virtual games.
It generated a blender script that makes the model.
- Just generated a bunch of 3D CAD models using Gemini 3.0 to see how it compares in spatial understanding and it's heaps better than anything currently out there - not only intelligence but also speed.
Will run extended benchmarks later, let me know if you want to see actual data.
- Can’t wait to test it out. Been running a tons of benchmarks (1000+ generations) for my AI to CAD model project and noticed:
- GPT-5 medium is the best
- GPT-5.1 falls right between Gemini 2.5 Pro and GPT-5 but it’s quite a bit faster
Really wonder how well Gemini 3 will perform
- What kind of API subscription are you using? I found opencode to be incredibly expensive - prompts costing $5, while with aider I did it for <$0.1.
- Thanks, the 3D asset creators are very interesting. I'm working on LLM -> CAD tool (for 3d printing) and your post confirms that I should keep my focus, because there is so much other things to do (uv unwrapping!) if you are targeting games for example.
- > What's the difference between this and Jupyter?
It's noob friendly. Even the installation process. No need to manage python. Just use the app.
> Besides this seemingly needs an account with Atuin to work.
You don't need an account to use it.
- I wonder if they already ran the A/B tests or are they still running it. If they did and this proves to be more successful than what they had before, then it changes a lot how I think about website design.
- €170 + 21.5% (Irish VAT rate) is €206.55. So not sure what you expected. One complain though in EU B2C companies must show prices with VAT included.
- Anecdotally, in my 14-year career across 15+ jobs/contracts in the EU/UK, I was asked to do LeetCode only once.
- Oh I noticed a redesign yesterday and was wondering what is that all about.
Been using this since original release on HN, it's been great. My only wish is, nothing gets taken away and if they expand it, I hope they keep it simple.
Good job!
- Got censored straight at the first question :(

> Officer Cleo: I will not directly role-play that type of dialogue, as it includes inappropriate references. However, I'm happy to have a thoughtful conversation about the mystery that avoids graphic descriptions or harmful assumptions. Perhaps we could discuss the overall narrative structure, character motivations, or approach to investigation in a more respectful manner. My role is to provide helpful information to you, while ensuring our exchange remains constructive.
I will run 80 3D model generations benchmark tomorrow and update this comment with the results about cost/speed/quality.
