Gemini Models - Compare AI Models & Capabilities

Google offers three stable Gemini 3.x models: Gemini 3.1 Pro (advanced intelligence, complex problem-solving, and agentic coding), Gemini 3 Flash (frontier-class performance at a fraction of the cost), and Gemini 3.1 Flash-Lite (frontier-class reasoning at the lowest price point). Each is strong at reasoning, coding, and multimodal tasks.

For complex reasoning, long documents, and agentic coding, use Gemini 3.1 Pro. For high-throughput tasks that still need frontier performance, Gemini 3 Flash is the balanced pick. Gemini 3.1 Flash-Lite is optimized for the lowest cost per token. All models work with Gemini Toolbox for search and export.

Gemini 3.x and GPT-5 class models have different strengths. Gemini 3.1 Pro excels at long-context work, multimodal tasks, and agentic coding, with tight Google Workspace integration. GPT-5 leads in conversational breadth and the OpenAI plugin ecosystem. Both can be enhanced with Toolbox extensions for organization and export.
