Deep dive
On shared benchmark coverage, Google-Proof Q&A has Falcon 180B at 58.9 and Gemini 3.1 Pro Preview at 94.3, with Gemini 3.1 Pro Preview ahead by 35.4 points; Massive Multitask Language Understanding has Falcon 180B at 84.2 and Gemini 3.1 Pro Preview at 98, with Gemini 3.1 Pro Preview ahead by 13.8 points. The largest visible gap is 35.4 points on Google-Proof Q&A, 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: 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, structured outputs: Gemini 3.1 Pro Preview, and code execution: Gemini 3.1 Pro Preview. Both models share the core language-model surface, 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.
Pricing coverage is uneven: Falcon 180B has no token price sourced yet and Gemini 3.1 Pro Preview has $2/1M input tokens. Provider availability is 2 tracked routes versus 5. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Falcon 180B when provider fit are central to the workload. Choose Gemini 3.1 Pro Preview when coding workflow support and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Is Falcon 180B or Gemini 3.1 Pro Preview open source?
Falcon 180B is listed under Apache 2.0. Gemini 3.1 Pro Preview is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Falcon 180B or Gemini 3.1 Pro Preview?
