Deep dive
On shared benchmark coverage, Google-Proof Q&A has GPT-5.5 at 93.6 and Qwen3.6 Max Preview at 86, with GPT-5.5 ahead by 7.6 points. The largest visible gap is 7.6 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 code execution: GPT-5.5. Both models share vision, multimodal input, reasoning mode, and function calling, 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, GPT-5.5 lists $5/1M input and $30/1M 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 Qwen3.6 Max Preview lower by about $9.9 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose GPT-5.5 when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Qwen3.6 Max Preview 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.
