Deep dive
On shared benchmark coverage, MMLU PRO has DeepSeek V4 Pro at 87.5 and Qwen3.6-35B-A3B at 85.2, with DeepSeek V4 Pro ahead by 2.3 points; SWE-bench Verified has DeepSeek V4 Pro at 80.6 and Qwen3.6-35B-A3B at 73.4, with DeepSeek V4 Pro ahead by 7.2 points; SWE-bench Pro has DeepSeek V4 Pro at 55.4 and Qwen3.6-35B-A3B at 49.5, with DeepSeek V4 Pro ahead by 5.9 points. The largest visible gap is 7.2 points on SWE-bench Verified, 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: Qwen3.6-35B-A3B, multimodal input: Qwen3.6-35B-A3B, reasoning mode: DeepSeek V4 Pro, and structured outputs: DeepSeek V4 Pro. Both models share 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, DeepSeek V4 Pro lists $0.43/1M input and $0.87/1M output tokens on the cheapest tracked provider, while Qwen3.6-35B-A3B lists $0.15/1M input and $1/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3.6-35B-A3B lower by about $0.16 per million blended tokens. Availability is 5 providers versus 2, so concentration risk also matters.
Choose DeepSeek V4 Pro when reasoning depth, larger context windows, and broader provider choice are central to the workload. Choose Qwen3.6-35B-A3B when coding workflow support 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.
