This article delves into the complex infrastructure required to run large language models (LLMs) like ChatGPT. It explains that LLMs are essentially large sets of numerical parameters that must fit into GPU memory. The process involves tokenizing user input, with requests handled in two phases: 'prefill' for prompt processing and 'decode' for token generation. To manage large models and high traffic, techniques like sharding, replication, and LLM-aware routing are employed, often orchestrated by systems like Kubernetes for large GPU fleets. AI
