Google's Gemini model family, currently in its fourth generation, presents a confusing array of tiers and naming conventions for developers. The latest offerings include Gemini 3.1 Pro for complex reasoning, Gemini 3 Flash for cost-effective and low-latency tasks, and Gemini 3 Nano for on-device applications. While Gemini Pro offers higher accuracy, Gemini Flash is sufficient for a majority of production workloads like summarization and classification, with the recommendation to use Flash by default and escalate to Pro only when necessary.
