关于 Gemini 3.1 Flash-Lite
了解 Gemini 3.1 Flash-Lite 的功能、特性以及它如何帮助您获得更好的效果。
专为高速智能而优化
Gemini 3.1 Flash-Lite 是 Google 的高速主力 model,专为需要极低 latency 和高成本效益的大规模开发者工作负载而设计。它于 2026 年 3 月 3 日发布,作为 Gemini 3.1 系列中的优化成员,其 time-to-first-token 速度比前代快 2.5 倍,输出速度提升了 45%。它能够以每秒超过 360 tokens 的速度进行 streaming,是实时应用和大规模数据处理的理想选择。
原生 Multimodal 与 100 万 Context
该 model 原生支持 multimodal,可在巨大的 100 万 token context window 内处理文本、图像、音频、视频和 PDF 输入。这使得开发者能够处理海量数据集(如长达一小时的视频或庞大的法律档案),而无需复杂的 RAG 流程。其视觉能力尤为出色,在文档视觉问答和图表分析方面表现优异。
精细的开发者控制
一个显著的特点是引入了 'Thinking Levels'(Minimal、Low、Medium、High)。这一 parameters 允许开发者根据任务复杂度精细地调高或调低 model 的 reasoning 深度。这种灵活性确保了用户在处理分类等简单任务时不会支付多余费用,同时在进行 UI 生成和数据提取等任务时仍能获得增强的逻辑支持。

Gemini 3.1 Flash-Lite 的使用案例
发现使用 Gemini 3.1 Flash-Lite 获得出色效果的不同方式。
高吞吐量实时翻译
以极低的 latency 和极高的成本效益,无缝处理跨 100 多种语言的数千条聊天消息或支持工单。
Multimodal 内容审核
利用原生视频和图像处理能力,在高吞吐量的社交媒体流或视频平台中标记违规内容。
自动化结构化数据提取
利用 100 万 tokens 的 context window,从庞大的 PDF 档案或长篇法律文档中提取复杂的 JSON schema。
敏捷前端原型设计
以每秒超过 360 tokens 的速度快速生成功能完备的 React/Tailwind UI 组件和落地页,加速迭代设计。
Agentic 任务编排
为“全天候” AI agents 提供动力,执行多步规划、网络搜索和工具调用,且不会超出 token 预算。
低 Latency 客户服务机器人
部署对话助手,根据查询的简易程度调节 reasoning 深度,提供即时响应。

“Google 让现在很难有理由在处理高吞吐量任务时去选择其他供应商。”
Gemini 3.1 Flash-Lite专业提示
专家提示助您充分利用Gemini 3.1 Flash-Lite。
灵活运用 Thinking Levels
对于分类等简单任务,将 thinking_level 设置为 'minimal' 以最大化速度;对于结构化代码生成,请使用 'high'。
原生视频分析
直接将原始视频文件输入 API,即可同时获取视觉事件和音频线索的快速洞察,无需经过转录步骤。
Context 优于 RAG
对于小于 100 万 tokens 的数据集,直接将整个文档集放入 context window,以消除检索错误并节省 vector DB 成本。
利用 Batching 优化
对于非紧急任务使用 Batching API 可进一步降低成本,Flash-Lite 专门针对异步处理进行了优化。
