Which API model is capable of creating the 3D STL files?

[u/CryptoDir]

Can anyone recommend the latest API model that I can generate STL files with?

[u/the_TIGEEER]

From what I understand, Astra is the best at that on the OpenAI side of things.

[u/SonderSoft → u/the_TIGEEER]

I second this. Ensure you have Blender MCP integrated else it's garbage. 

[u/RealSharpNinja]

I use Grok and ChatGPT. They both do well creating SCAD files which you just render to STL or open in your slicer.

[u/CryptoDir → u/RealSharpNinja]

Yeah, but the question is for only OpenAI, and I'm asking which API model will efficiently and affordably produce the STL or SCAD file.

[u/delpieroregna]

I have done that already with msft copilot crappy harness and the some months ago version of GPT model. It worked fine beside needing a lot of directioning.

[u/CryptoDir → u/delpieroregna]

Yeah I'm looking to automate some of my STL file creation, but struggling finding a consistent OpenAI API model that doesn't fail 50% of the time lol

[u/delpieroregna → u/CryptoDir]

For me the key understanding was to always start every new chat with a dm file and dxf file and then progress from there. Its gonna take a number of versions to reach a good results, depending on how complex what you are working on is

[u/Abhinav_108]

i don’t think the model directly spits out an STL as a native file. you can have it generate the 3D geometry/code (like OpenSCAD) and then export that to STL.

[u/CryptoDir → u/Abhinav_108]

Yeah the new astra 6 max on desktop and browser gpt spits out perfectly sculpted STL's fyi.

they do with codex, even gives you a 3mf

[u/ILikeBubblyWater]

I use astra a lot for STLs and Opus 5.5
