Deep dive
On shared benchmark coverage, MMLU PRO has DeepSeek R1 0528 at 85 and Qwen3-235B-A22B at 82.8, with DeepSeek R1 0528 ahead by 2.2 points; Google-Proof Q&A has DeepSeek R1 0528 at 81 and Qwen3-235B-A22B at 86.1, with Qwen3-235B-A22B ahead by 5.1 points; LiveCodeBench has DeepSeek R1 0528 at 73.3 and Qwen3-235B-A22B at 80.4, with Qwen3-235B-A22B ahead by 7.1 points. The largest visible gap is 7.1 points on LiveCodeBench, 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 R1 0528 and code execution: DeepSeek R1 0528. 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 R1 0528 lists $0.50/1M input and $2.15/1M output tokens on the cheapest tracked provider, while Qwen3-235B-A22B lists $0.09/1M input and $0.58/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3-235B-A22B lower by about $0.76 per million blended tokens. Availability is 6 providers versus 5, so concentration risk also matters.
Choose DeepSeek R1 0528 when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Qwen3-235B-A22B when provider fit 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.
