ChatGPT is a language model that runs on servers provided by OpenAI, which are located in data centers across the world. The specific servers used to run the model can vary depending on the resources required to support the workload. The exact specs of the servers are not public and can change frequently as OpenAI is continuously working to improve its infrastructure.
However, in general, the servers that run large language models like GPT-3 are typically equipped with powerful GPUs (Graphics Processing Units), such as NVIDIA A100 and V100, which are designed to handle the complex mathematical operations required to train a neural network. These GPUs have high memory capacity and a large number of CUDA cores, which allows them to handle large amounts of data and perform complex calculations quickly.
The servers also typically have high-end CPUs (Central Processing Units), such as Intel Xeon or AMD EPYC, and large amounts of memory and storage capacity to support the workload. Additionally, the servers run on a Linux operating system, and use distributed computing frameworks like CUDA and TensorFlow to train the model.
It’s important to note that the hardware and infrastructure used by OpenAI are constantly evolving and being updated to stay current with the latest technology and to support the growing demands of the models.
