Deep dive
On shared benchmark coverage, MMLU PRO has Gemini 3.1 Pro Preview at 91.0 and Qwen3.6 Max Preview at 88.5, with Gemini 3.1 Pro Preview ahead by 2.5 points; SWE-bench Verified has Gemini 3.1 Pro Preview at 80.6 and Qwen3.6 Max Preview at 78.8, with Gemini 3.1 Pro Preview ahead by 1.8 points; Google-Proof Q&A has Gemini 3.1 Pro Preview at 94.3 and Qwen3.6 Max Preview at 86, with Gemini 3.1 Pro Preview ahead by 8.3 points. The largest visible gap is 8.3 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 reasoning mode: Qwen3.6 Max Preview and code execution: Gemini 3.1 Pro Preview. Both models share vision, multimodal input, 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, Gemini 3.1 Pro Preview lists tiered pricing: 0-200,001t is $2/1M input and $12/1M output; 200,001t+ is $4/1M input and $18/1M output, while Qwen3.6 Max Preview lists tiered pricing: 0-128,000t is $1.30/1M input and $7.80/1M output; 128,000t+ is $2/1M input and $12/1M output. A 70/30 input-output blend puts Qwen3.6 Max Preview lower by about $2.40 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 5 providers versus 3, so concentration risk also matters.
Choose Gemini 3.1 Pro Preview when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Qwen3.6 Max Preview when reasoning depth and lower cheapest-tier input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
