Recommended free AI assistants for writing Babylon.js?

Questions
1

While Claude.ai is a good ai assistant for writing code in Babylon.js, any other similar alternatives? Gemini and ChatGPT produces tonnes of mistakes when writing code, so those are off

Personally I’ve found Codex - GPT-5.6 Sol to be pretty good. The major models keep leap-frogging each other and open-weight models like Kimi K3 are often times competitive also.

Artificial Analysis currently reports Claude and Codex on par in terms of performance, but Claude is a lot more expensive and slower per task.

Thanks, that said, are there any free ones that you don’t have to download that can solve coding problems, esp. for babylon.js?

When it comes to a highly specialized technology like 3D, free AI tools are ultimately not very useful.

I am using VSCode and there is a plugin I use called Kilo Code. The interface looks like this:

I find I can get a few requests using the ‘Auto Free’ mode each day before I have to switch to a paid account.

The local (free) models I’ve tried are super slow, while pinning resources, and give mediocre results.
The Cursor in-house models (their budget/free options) are quite good, not sure how much usage you get for free, maybe mix it in with GoOcto’s suggestion when you get throttled.

Thanks, this looks promising, must try it out
