Deep dive

On shared benchmark coverage, MMLU PRO has DeepSeek R1 0528 at 85 and Qwen3.6 Max Preview at 88.5, with Qwen3.6 Max Preview ahead by 3.5 points; SWE-bench Verified has DeepSeek R1 0528 at 57.6 and Qwen3.6 Max Preview at 78.8, with Qwen3.6 Max Preview ahead by 21.2 points; Google-Proof Q&A has DeepSeek R1 0528 at 81 and Qwen3.6 Max Preview at 86, with Qwen3.6 Max Preview ahead by 5 points. The largest visible gap is 21.2 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 Max Preview, multimodal input: Qwen3.6 Max Preview, function calling: Qwen3.6 Max Preview, tool use: Qwen3.6 Max Preview, 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 Qwen3.6 Max Preview lists tiered pricing: 0-128,000t is $1.30/1M input and $7.80/1M output; 128,000t+ is $2/1M input and $12/1M output. A 70/30 input-output blend puts DeepSeek R1 0528 lower by about $1.60 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 7 providers versus 3, so concentration risk also matters.

Choose DeepSeek R1 0528 when coding workflow support, lower input-token cost, and broader provider choice are central to the workload. Choose Qwen3.6 Max Preview when long-context analysis and larger context windows are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, DeepSeek R1 0528 or Qwen3.6 Max Preview?

Qwen3.6 Max Preview supports 256k tokens, while DeepSeek R1 0528 supports 130k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, DeepSeek R1 0528 or Qwen3.6 Max Preview?

DeepSeek R1 0528 lists $0.50/1M input and $2.15/1M output tokens on the cheapest tracked provider. Qwen3.6 Max Preview lists tiered pricing: 0-128,000t is $1.30/1M input and $7.80/1M output; 128,000t+ is $2/1M input and $12/1M output.
