Deep dive
On shared benchmark coverage, SWE-bench Verified has Gemini 3.1 Pro Preview at 80.6 and Qwen3-Max at 78.8, with Gemini 3.1 Pro Preview ahead by 1.8 points; MultiChallenge has Gemini 3.1 Pro Preview at 71.4 and Qwen3-Max at 41.2, with Gemini 3.1 Pro Preview ahead by 30.2 points; τ-bench has Gemini 3.1 Pro Preview at 76.5 and Qwen3-Max at 76.8, with Qwen3-Max ahead by 0.3 points. The largest visible gap is 30.2 points on MultiChallenge, 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 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 $2/1M input and $12/1M output tokens, while Qwen3-Max lists $0.78/1M input and $3.9/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3-Max lower by about $3.28 per million blended tokens. Availability is 4 providers versus 1, 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-Max when vision-heavy evaluation and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
