ChatGPT is an AI language model developed by OpenAI, built on the GPT (Generative Pre-trained Transformer) architecture. It is designed to generate human-like text based on input prompts. ChatGPT is primarily built using the following programming languages:

1. Python – The core language used for training, fine-tuning, and running the machine learning models, including deep learning frameworks like TensorFlow and PyTorch.

2. C++ – Used for performance optimization in low-level operations, particularly in the underlying GPU and CPU computation.

3. CUDA – Used for GPU acceleration, allowing ChatGPT to efficiently process and generate text using NVIDIA GPUs.

4. Rust – Sometimes used in performance-critical sections, such as memory safety and parallel processing.

5. JavaScript/TypeScript – Used for frontend development when integrating ChatGPT into web applications.

6. Go & Bash – Used in backend infrastructure, deployment automation, and server management.
