Qwen: Qwen3.5 397B A17B
This AI model, Qwen3.5 397B A17B, is offered by vendor qwen and supports multiple input modalities: text, image, and video. It can process lengthy context, up to 262144 bytes, but has a limit of 235929 tokens for each completion. The model also allows use with tools and supports complex reasoning. Given its price point, Qwen may be worth shortlisting for users who need to integrate multiple input types or have specific requirements for contextual understanding. The model's blended benchmark score is 55.4 across two independent tests, which indicates a decent standing in the field but should not overshadow potential drawbacks. At $0.55 per million input tokens and $3.5 per million output tokens, users weighing cost against capabilities may find Qwen a suitable option to consider further evaluation.
