Deep dive
The capability footprint differs most on code execution: Gemini 3.1 Flash-Lite. Both models share vision, multimodal input, function calling, and tool use, 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 2.5 Pro Computer Use Preview lists $1.25/1M input and $10/1M output tokens, while Gemini 3.1 Flash-Lite lists $0.25/1M input and $1.5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemini 3.1 Flash-Lite lower by about $3.25 per million blended tokens. Availability is 2 providers versus 2, so concentration risk also matters.
Choose Gemini 2.5 Pro Computer Use Preview when vision-heavy evaluation are central to the workload. Choose Gemini 3.1 Flash-Lite when coding workflow support 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. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
