ChatGPT, the AI chatbot developed by OpenAI and Microsoft, relies on a powerful hardware infrastructure to deliver its impressive capabilities. At the core of this infrastructure are NVIDIA V100 and A100 GPU clusters, specifically designed for AI and analytical applications.
The NVIDIA A100 GPU, the primary hardware component of ChatGPT, is not your average gaming GPU. It is purpose-built for AI applications, lacking a display output. It comes in two versions: a PCI Express version and an SXM4 version. The SXM4 version, preferred in data centers, can handle higher electrical power loads, allowing for superior performance by utilizing up to 500 watts.
The NVIDIA V100 Tensor Core is another critical GPU used in ChatGPT. It is designed for high-performance computing, data science, and graphics rendering. With its cutting-edge Volta architecture, the V100 delivers remarkable performance, equivalent to as many as 32 CPUs consolidated into a single GPU. Its 640 Tensor Cores enable it to surpass the 100 teraFLOPS barrier, setting a new standard for deep learning performance.
The GPUs powering ChatGPT are interconnected using a high-speed NVLink, enabling them to function as a single, large GPU. While the exact number of GPUs used remains undisclosed, estimates suggest that around 30,000 A100s are currently in operation. Training the AI model likely required around 4,000 to 5,000 GPUs, but the massive user base of 100 million users necessitates approximately six times more GPUs.
In addition to GPUs, ChatGPT also utilizes CPUs for specific tasks that are less suited for GPUs, such as loading data and running the chat interface. Storage plays a crucial role, with SSDs or cloud storage used to store the extensive datasets and models. A high-speed network provided by a dedicated data center allows ChatGPT to communicate seamlessly with users and other systems.
Microsoft’s investment in the ChatGPT system is estimated to be in the hundreds of millions of dollars, with significant daily operational costs. The company is also integrating newer NVIDIA H100 GPUs into its Azure Cloud AI service, further enhancing performance and enabling the training of more complex language models.
The hardware used to power ChatGPT continues to evolve as new technologies emerge, ensuring that the chatbot becomes even more powerful and efficient over time. It serves as a testament to the potential of artificial intelligence and the advancements in modern hardware.
