Context
Context window
Qwen3.8 Max Prime accepts up to 1,000,000 tokens per request, roughly 750,000 English words or 1,500 pages. That budget is shared between your prompt and the reply, and a single reply is capped at 131,072 tokens.
Filling the whole window with one prompt costs about $4.00 at list price, so for repeated long-document work, retrieval (sending only the relevant parts) or prompt caching is usually much cheaper.
