Large open Qwen multimodal MoE for visual agents and long technical tasks
Qwen3.5 397B-A17B by alibaba is offered by 35 providers on this page. Public prices are shown for 32 of them. Its official list price is $0.60 per 1M input tokens and $3.60 per 1M output tokens. The lowest paid channel is AIHubMix at $0.164 / $0.986 per 1M, about 4.9× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it. 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.
Artificial Analysis rates it 21.4 on the Intelligence Index. Against its lowest blended price of $0.37 per 1M, that is roughly 58 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 82 tokens per second, with 2.13s to the first token.
The context window is 262,144 tokens at the reference host, but hosts report different limits, from 131,072 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, Video, and Audio. 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.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
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.
