LLM — A large language model — the neural network behind tools like Claude and ChatGPT, trained on huge amounts of text to predict what comes next.
token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
Why it matters
Prefill-only scoring is a different serving workload from chat generation; this names which parts of an open-source LLMA large language model — the neural network behind tools like Claude and ChatGPT, trained on huge amounts of text to predict what comes next.Full definition → server — batching, prefix reuse, GPU execution, Python runtime behavior — have to change to meet strict latency SLAs.
