2月25日消息人工智能初创公司Anthropic今天宣布推出Claude 3.7 Sonnet称这是其迄今为止最智能的模型也是市场上首款混合推理模型。该公司介绍Claude 3.7 Sonnet仅用一个模型实现了两种思考方式既能提供接近即时的响应也能展示分步骤的详细思考过程。 该公司称Claude 3.7 Sonnet这种“混合型”模型同时具备“推理模式”停下来思考复杂答案与传统模式实时生成答案的能力并表示该模型是市面上唯一的此类“混合”模型。此外Claude 3.7 Sonnet在编程领域的表现尤为突出并且能精准控制思考时间。 介绍
大力吸引资金的初创企业与科技巨头们争夺AI领域领导权的战争已经白热化。Anthropic周一发布名为Claude 3.7 Sonnet的模型该公司表示这是其有史以来“最智能”的AI模型称这种“混合型”模型同时具备“推理模式”停下来思考复杂答案与传统模式实时生成答案的能力。 Anthropic联合创始人兼首席科学官Jared Kaplan在接受媒体采访时表示“这个模型融合了所有功能——我们的目标是拥有一个统一的AI能适用于各种场景。这样对我们的客户而言会更简单一些。” “市面上唯一的混合模型”
Anthropic称Claude 3.7 Sonnet是市面上唯一的此类“混合”模型并将立即投入使用。 Kaplan将其比作人类大脑的运行方式有的问题需要深度思考有的问题需要快速作答。 但Anthropic希望将这两种能力整合在同一个模型中而不是完全分开。 分析认为这一举措或许能为Anthropic在与对手OpenAI以及那些投入巨资开发AI模型的大型科技公司的竞争中赢得急需的优势。 Anthropic的聊天机器人Claude与OpenAI的ChatGPT以及谷歌Google的Gemini竞争激烈。 另据媒体报道Anthropic正与Lightspeed和谷歌洽谈一笔高达20亿美元的融资估值将达到600亿美元。另外亚马逊对该初创企业的投资约为80亿美元。 曾参与共同创立Instagram的Anthropic产品主管Mike Krieger对媒体表示这种混合方法能简化聊天机器人的使用流程让用户无需思考究竟哪种功能最适合。 他说让用户也可以选择模型或者让模型思考多久对普通用户有些复杂他希望用户在使用时不必过多操心。 Krieger说用户可以选择开启或关闭混合选项来保持简单性并根据自己的工作需求为模型设定一个“时间预算”。 Anthropic还计划于周一推出一款用于编程的代理工具。Anthropic近期在一些产品发布上赢得了先机。
卓越的编程能力、精准控制思考时间
Claude 3.7 Sonnet在编程领域的表现尤为突出。它在编码和前端网页开发方面展现了显著的改进能够处理复杂的代码库并在高级工具使用上表现出色。 在多个测试中Claude 3.7 Sonnet都展现出了卓越的编码能力。 例如Cursor指出Claude在现实编码任务中再次被评为最佳模型特别是在处理复杂代码库和高级工具使用等方面有显著改进。 Cognition发现它在规划代码变更和处理全栈更新方面远胜其他模型。 Vercel强调了Claude在复杂代理工作流中的卓越精度而Replit成功地部署了Claude来从零开始构建复杂的网络应用程序和仪表板而其他模型则会停滞不前。在Canva的评估中Claude始终能够生成具有卓越设计品味的生产就绪代码并显著减少了错误。 Claude 3.7 Sonnet不仅能够产生近乎即时的回应或进行可让用户看到的、逐步深入的思考并且 API 用户可以精细控制模型思考的时间长短。 此外用户还可以通过API控制思考的预算告诉Claude思考不超过N个标记N可以是任何值最高可达其128K标记的输出限制。 这种灵活性使得用户可以在速度和成本与回答质量之间进行权衡。
