LLM Inference Explained: The Engineering Challenge of Running AI Models

By PulseAugur Editorial · [1 sources] ·

LLM inference is the process by which a trained AI model generates responses to user prompts, distinct from the training phase where the model learns. This process involves several stages, including tokenization, prefill, and decoding, with decoding being a slower, iterative step. At scale, inference presents significant engineering challenges related to speed, memory usage for KV caches, and cost, leading to techniques like batching, optimized KV cache management, quantization, and distributed serving to balance user experience and resource efficiency.

    What Is LLM Inference?

    <p>Inference is what happens every time you send a prompt to an AI model: the model uses what it already learned to produce an answer, without learning anything new.</p> <p>You hear the word everywhere. "Inference costs", "inference providers", "fast inference". It sounds technic…
