Deep dive
On shared benchmark coverage, Google-Proof Q&A has DeepSeek V4 Pro at 90.1 and Qwen2.5-72B-Instruct at 38.4, with DeepSeek V4 Pro ahead by 51.7 points; HumanEval has DeepSeek V4 Pro at 76.8 and Qwen2.5-72B-Instruct at 86.6, with Qwen2.5-72B-Instruct ahead by 9.8 points; Chatbot Arena has DeepSeek V4 Pro at 1460 and Qwen2.5-72B-Instruct at 1270, with DeepSeek V4 Pro ahead by 190 points. The largest visible gap is 190 points on Chatbot Arena, 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: DeepSeek V4 Pro, function calling: DeepSeek V4 Pro, and tool use: DeepSeek V4 Pro. Both models share structured outputs, 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 Qwen2.5-72B-Instruct lists $0.18/1M input and $0.54/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen2.5-72B-Instruct lower by about $0.28 per million blended tokens. Availability is 5 providers versus 7, so concentration risk also matters.
Choose DeepSeek V4 Pro when reasoning depth and larger context windows are central to the workload. Choose Qwen2.5-72B-Instruct when provider fit, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
