Qwen: Qwen3.5 397B A17B

The Qwen3.5 series 397B-A17B native vision-language model is built on a hybrid architecture that integrates a linear attention mechanism with a sparse mixture-of-experts model, achieving higher inference efficiency. It delivers state-of-the-art performance comparable to leading-edge models across a wide range of tasks, including language understanding, logical reasoning, code generation, agent-based tasks, image understanding, video understanding, and graphical user interface (GUI) interactions. With its robust code-generation and agent capabilities, the model exhibits strong generalization across diverse agent.

Tool useVisionReasoning

Why it stands out

262K-token context window handles longer documents and multi-turn conversations without truncation.
Combines tool use with reasoning — a strong baseline for agentic and multi-step workflows.
Multimodal input (vision) extends it beyond text-only workflows.
$0.39/M input makes it practical for always-on agents, batch processing, or high-volume classification.
