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.
context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
Why it matters
It gives teams training long-context windowThe maximum amount of text a model can consider at once — its working memory for the current conversation or task.Full definition → models a specific, benchmarked technique stack (FSDP, DeepSpeed Ulysses, activation checkpointing, CPU offload, chunked training) for reaching multi-million-tokenThe chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.Full definition → context without exceeding GPU memory.
