Long-context models

long context LLM API, 1M token context, large document analysis

Long context lets you skip a retrieval pipeline, but it does not make long context free: input tokens are billed whether they are cached or not, and a 200K-token prompt costs the same as the output of hundreds of normal requests. Repeated prefixes are the case where the platform's cache-aware routing pays off — keep the stable part of the prompt (system instructions, documents) at the front and the volatile part at the end, and repeated calls against the same prefix cost materially less.
