Deep dive
The capability footprint differs most on vision: Gemini 3.1 Pro Preview, multimodal input: Gemini 3.1 Pro Preview, function calling: Gemini 3.1 Pro Preview, tool use: Gemini 3.1 Pro Preview, and code execution: Gemini 3.1 Pro 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, Gemini 3.1 Pro Preview lists tiered pricing: 0-200,001t is $2/1M input and $12/1M output; 200,001t+ is $4/1M input and $18/1M output, while Qwen3-Next-80B-A3B lists $0.10/1M input and $0.78/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3-Next-80B-A3B lower by about $4.70 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 5 providers versus 4, so concentration risk also matters.
Choose Gemini 3.1 Pro Preview when coding workflow support and broader provider choice are central to the workload. Choose Qwen3-Next-80B-A3B 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.
FAQ
Which is cheaper, Gemini 3.1 Pro Preview or Qwen3-Next-80B-A3B?
Gemini 3.1 Pro Preview lists tiered pricing: 0-200,001t is $2/1M input and $12/1M output; 200,001t+ is $4/1M input and $18/1M output. Qwen3-Next-80B-A3B lists $0.10/1M input and $0.78/1M output tokens on the cheapest tracked provider.
