Qwen instruction model for multilingual chat, reasoning, and tool use
Qwen3 8B by alibaba is offered by 9 providers on this page. Its official list price is $0.18 per 1M input tokens and $0.70 per 1M output tokens. The lowest paid channel is SiliconFlow at $0.06 / $0.06 per 1M, about 13× below the list price.
Artificial Analysis rates it 7.3 on the Intelligence Index, with 9 for coding and 0.8 for agentic tasks. Against its lowest blended price of $0.06 per 1M, that is roughly 122 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 41 tokens per second, with 3.76s to the first token.
The context window is 131,072 tokens at the reference host, but hosts report different limits, from 40,960 to 131,072, so the usable window depends on the provider you pick. It supports reasoning and tool use. 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 2025-03-31.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
