Which OpenAI model is the most code oriented?

API
1

Hi all,

On several youtube videos, I got the information that gpt-4.1 series are a bit code oriented, but I had no official truth reference about that.

But we also have other models available, such as gpt-4.5 series, and also o4 series…

So the question would be: are you aware of any reference stating which model is it better to chose if the main focus is code?

Thanks a lot.

  • gpt-4.5 is best suited for creative writing, it’s not bad for coding but it’s expensive.
  • gpt-4.1 has the largest input token context (1 million), which makes it interesting for complex coding but since it is only available on api you would have to either use the playground or some tool like Windsurf, Github Copilot or Codex CLI
  • In the API you can still try using o3-mini-high, which was as good as o3/o4-mini but returns a more complete code (o3 / o4-mini often tells you what changed but will cut your code in
    pieces and you will spend extra prompts telling it to give a full code).

I particularly am still using ChatGPT Plus (not the API) for most coding tasks where gpt-4o is alright, leaving o3 / o4-mini for more complex problems, but I don’t rely entirely on AI. I mostly use it as an assistant. So, in the end it depends on what your needs are and expectations.

o1 and o3-mini-high were the only models that could reliably work with code if it is longer than 150-250 lines, in a manner that rivals Grok-3. o3-mini-high was like a less intelligent version of Grok-3 but still capable to work with 1000 lines of code. 4o is still good on the micro-scale, like you can write mockup code “filter x for y with this regex …” and it will so to speak auto-complete or write smaller functions or tell you what is wrong or how to fix error fast. And yeah if things are not too complicated and it stays within the comfort zone of 150 lines possibly you can go beyond that somewhat but not 100% of the time. I mean it is very useful for very fast answers, but it is literally downgraded in capabilities more than one generation, where it can only assist you and not write all code entirely on its own. All the newer models at least on Plus tier they make too many errors and hallucinate too much, they are hardly usable in this state. Better just use Grok-3, it is free and will save you so much time. And o1 was never even better than Grok-3 it was just different. So even accessing it via API for a hefty price hardly makes sense .
