Deep dive
The capability footprint differs most on code execution: Grok 4. Both models share vision, multimodal input, reasoning mode, and function calling, 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, Grok 4 lists $1.25/1M input and $2.50/1M 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 Grok 4 lower by about $0.97 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 Grok 4 when coding workflow support and broader provider choice are central to the workload. Choose Qwen3.6 Max Preview when vision-heavy evaluation and lower cheapest-tier input-token cost 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, Grok 4 or Qwen3.6 Max Preview?
Grok 4 supports 256k tokens, while Qwen3.6 Max Preview supports 256k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, Grok 4 or Qwen3.6 Max Preview?
Grok 4 lists $1.25/1M input and $2.50/1M 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. Compare the tier you will actually use; cheap async pricing can overstate savings for interactive workflows. Provider discounts or batch pricing can still change the final bill.
