Gemini 3 1 Pro模型特点

核心能力

能力一览与工程实践价值

Chat and reasoning

Supports multi-turn context and structured outputs.

Streaming output

SSE token streaming for real-time UX.

Tool calling

Compose retrieval/execution workflows with tools.

如何使用 Gemini 3 1 Pro API

  1. Set Authorization: Bearer <YOUR_API_KEY>.
  2. Call chat endpoint with model, messages, and max_tokens.
  3. Enable stream or tools when needed.
  4. Handle stop_reason for completion or tool continuation.
Gemini 3 1 Pro

适用场景

  • When building coding/Q&A assistants and task agents.
  • When streaming and tool-calling are required.

API 运行特性

  • API calls are stateless; pass full context via messages.
  • With stream=true, responses return as SSE events.
