Deep dive

On shared benchmark coverage, Google-Proof Q&A has Qwen3.5-397B-A17B at 89.3 and Qwen3.6 Max Preview at 86, with Qwen3.5-397B-A17B ahead by 3.3 points; Massive Multi-discipline Multimodal Understanding has Qwen3.5-397B-A17B at 85 and Qwen3.6 Max Preview at 82, with Qwen3.5-397B-A17B ahead by 3 points. The largest visible gap is 3.3 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.

The capability footprint differs most on vision: Qwen3.6 Max Preview. Both models share multimodal input, reasoning mode, function calling, and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, Qwen3.5-397B-A17B lists $0.39/1M input and $2.34/1M output tokens, while Qwen3.6 Max Preview lists $1.04/1M input and $6.24/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3.5-397B-A17B lower by about $1.62 per million blended tokens. Availability is 3 providers versus 2, so concentration risk also matters.

Choose Qwen3.5-397B-A17B when long-context analysis, larger context windows, and lower input-token cost are central to the workload. Choose Qwen3.6 Max Preview when vision-heavy evaluation are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
