Where Qwen3.5-9B sits on price
At $0.15 per million output tokens, Qwen3.5-9B is a budget tier model — 13.9× cheaper than the median output price of $2.08, which puts it in the cheapest 10% of everything we track. It sits 2th cheapest of the 53 Alibaba (Qwen) models we track. Output is only 1.5× the input price, an unusually flat spread: long prompts hurt about as much as long answers, so prompt size is where the savings are.

› What does it cost to fill Qwen3.5-9B's 262K context window?
Sending 262K of input in a single request costs $0.0262 at $0.1 per million tokens — before any output. There is no cached-input tier on this model, so every repeat of that context is billed at full price. This is why large context windows are cheap to advertise and expensive to actually use.
› Is Qwen3.5-9B worth the price?
Qwen3.5-9B is in the cheapest end of the market — cheaper than 97% of the models we track. At this price the question is not cost but capability: it is a good fit for classification, extraction, routing and bulk summarisation, and a poor fit for multi-step reasoning where a wrong answer costs more than the tokens saved.
