右侧 Playground 可直接调试：在 x-goog-api-key 填 sk-your-api-key（API易令牌，无需 Google Key），默认示例已把思考调至 low，点击发送即可看到响应。

模型默认开启深度思考，成本敏感场景传 thinkingConfig: {"thinkingLevel": "minimal"} 或 {"thinkingBudget": 0}。搜索 grounding、代码执行、URL context、Maps 等工具仅本原生端点支持。模型能力、定价、思考档位实测详见 Gemini 3.6 Flash 概览。

• 流式请求把 URL 改为 :streamGenerateContent?alt=sse（Playground 演示非流式）
• 代码执行工具实测可用，但 executableCode / codeExecutionResult 字段暂不回显，结果在正文中呈现
• :countTokens 与显式缓存 cachedContents 平台暂未开通

参数说明速查

参数	类型	必填	说明
contents	array	✓	对话内容，parts 内可混排 text 与 inlineData（base64 图像/PDF/音频/视频）
systemInstruction	object		系统指令
generationConfig.thinkingConfig.thinkingLevel	string		minimal / low / medium / high，实测思考 0/403/487/837 tokens
generationConfig.thinkingConfig.includeThoughts	bool		回显思考过程（thought: true 的 part）
generationConfig.responseMimeType + responseSchema			结构化输出（JSON Schema）
tools	array		google_search / url_context / codeExecution / google_maps / functionDeclarations

​

响应要点

• 思考消耗看 usageMetadata.thoughtsTokenCount（计入输出计费）
• grounding 工具命中时 candidates[0].groundingMetadata 返回来源；URL context 看 urlContextMetadata
• 隐式缓存命中看 usageMetadata.cachedContentTokenCount（概率命中，勿依赖）
