Where Qwen3 VL 8B Thinking sits on price
At $2.10 per million output tokens, Qwen3 VL 8B Thinking is a mid tier model — right at the median output price of $2.00, which puts it cheaper than 49% and pricier than 51% of the models we track. It sits 39th cheapest of the 53 Alibaba (Qwen) models we track.
