Google’s Gemini 3.x family has expanded rapidly through 2026. Here is every current model, its pricing, strengths, and best use case.
Gemini 3 Pro and 3.1 Pro
Gemini 3 Pro ($2/$12) was the original frontier model. Gemini 3.1 Pro (same pricing) improved reasoning and added a 2M token context window. Both offer native multimodal (text, image, audio, video). Best for research, analysis, and Google Workspace integration.
Gemini 3.5 Flash and 3.6 Flash
Gemini 3.5 Flash ($0.15/$0.60) is Google’s speed leader at 75.5 BenchLM. Gemini 3.6 Flash (75.5) is the latest, offering the same score with improved latency. Both outperform models at much higher price points. Flash-Lite variants offer extreme cost savings for simple tasks.
When to Use Each
Choose Pro for maximum capability and multimodal. Choose Flash for speed, cost efficiency, and high throughput. The gap between Flash and Pro has narrowed dramatically — Flash now rivals Pro on many benchmarks while costing a fraction.
