Qwen reasoning model for deliberate problem solving, math, and coding
Qwen3 235B A22B Thinking 2507 by alibaba is offered by 15 providers on this page. Public prices are shown for 12 of them. Its reference price is $0.40 per 1M input tokens and $4.00 per 1M output tokens. The lowest paid channel is IO.NET at $0.11 / $0.60 per 1M, about 4.1× below the reference price. It also has 2 free ($0) channels; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
The context window is 131,072 tokens at the reference host, but hosts report different limits, from 128,000 to 262,144, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, PDF, and Video. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-04.
