Qwen vision-language model for visual reasoning, documents, and agent tasks
Qwen3.5 Flash by alibaba is offered by 13 providers on this page. Its official list price is $0.10 per 1M input tokens and $0.40 per 1M output tokens. The lowest paid channel is AIHubMix at $0.028 / $0.282 per 1M, about 3.5× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
The context window is 1,000,000 tokens at the reference host, but hosts report different limits, from 991,808 to 1,020,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, Video, and PDF. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-01-01.
