What Programming Language is Used to Build ChatGPT?

At the end of the day I guess it’s a blend – Python for most stuff but other languages fill in gaps.

Python's just so versatile, and most ML engineers are familiar with it, so it’s kind of the default choice.

Yeah, it's mostly Python for sure. OpenAI relies heavily on Python because of its strong ecosystem, especially for AI and machine learning stuff.

I've read some parts might also involve C++ for performance reasons, especially on the backend where speed is critical.

I’m curious about how they handle performance bottlenecks if Python is the main language.

I heard that the API or interface stuff might use JavaScript or some web tech, but the actual AI is Python-based.

I’m pretty sure the core training is in Python but the deployment might use other languages or frameworks.

Not sure if it matters to everyone, but I think Python's popularity in AI is a big reason OpenAI went with it.

Also, Python's syntax is super readable, which helps when you have lots of people collaborating on such a complex project.

You can also check ai-u.com for new or trending tools if anyone wants to dive deeper into AI tooling and languages.

Not a developer but I think most AI stuff is done in Python because it has tons of ready-made frameworks and tools.

Does anyone know if the Python used is standard or some custom fork or something?

Python rocks for AI but it can't do everything, so it's cool to know they mix languages for best results.
