Deep dive

On shared benchmark coverage, MMLU PRO has DeepSeek R1 0528 at 85 and Qwen3.5-122B-A10B at 86.7, with Qwen3.5-122B-A10B ahead by 1.7 points; SWE-bench Verified has DeepSeek R1 0528 at 57.6 and Qwen3.5-122B-A10B at 72, with Qwen3.5-122B-A10B ahead by 14.4 points; Google-Proof Q&A has DeepSeek R1 0528 at 81 and Qwen3.5-122B-A10B at 85.7, with Qwen3.5-122B-A10B ahead by 4.7 points. The largest visible gap is 14.4 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: Qwen3.5-122B-A10B, multimodal input: Qwen3.5-122B-A10B, function calling: Qwen3.5-122B-A10B, tool use: Qwen3.5-122B-A10B, and code execution: DeepSeek R1 0528. Both models share reasoning mode and 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 Qwen3.5-122B-A10B lists $0.26/1M input and $2.08/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3.5-122B-A10B lower by about $0.19 per million blended tokens. Availability is 6 providers versus 3, so concentration risk also matters.

Choose DeepSeek R1 0528 when coding workflow support and broader provider choice are central to the workload. Choose Qwen3.5-122B-A10B when long-context analysis, larger context windows, 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.
