Deep dive
On shared benchmark coverage, MMLU PRO has Qwen2-72B at 64.4 and Qwen3.6 Max Preview at 88.5, with Qwen3.6 Max Preview ahead by 24.1 points. The largest visible gap is 24.1 points on MMLU PRO, 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, reasoning mode: Qwen3.6 Max Preview, function calling: Qwen3.6 Max Preview, and tool use: Qwen3.6 Max Preview. 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, Qwen2-72B lists $0.45/1M input and $0.65/1M 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 Qwen2-72B lower by about $2.09 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 4 providers versus 3, so concentration risk also matters.
Choose Qwen2-72B when provider fit, lower input-token cost, and broader provider choice are central to the workload. Choose Qwen3.6 Max Preview when reasoning depth 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, Qwen2-72B or Qwen3.6 Max Preview?
Qwen3.6 Max Preview supports 256k tokens, while Qwen2-72B supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, Qwen2-72B or Qwen3.6 Max Preview?
Qwen2-72B lists $0.45/1M input and $0.65/1M output tokens on the cheapest tracked provider.
