Context
Context window
Qwen3.8 Flash 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 $0.15 at list price, so for repeated long-document work, retrieval (sending only the relevant parts) or prompt caching is usually much cheaper.
