Openai 异步客户端接入国产大模型 Kimi

介绍

Kimi Chat 是由月之暗面科技有限公司（Moonshot AI）开发的一款人工智能助手，支持长达20万字的上下文处理能力，并且能够记住之前的对话内容，提供更加准确和有条理的回答。Kimi Chat 的特点在于其强大的长文本处理能力，这使得它能够在多轮对话中保持对上下文的理解和记忆，减少了信息丢失和误解，提高了对话的连贯性和准确性。

Moonshot AI 是一家专注于通用人工智能领域的公司，其愿景是寻求将能源转化为智能的最优解，通过产品与用户共创智能，实现普惠AI。Moonshot AI 的核心团队曾参与开发Transformer XL、RoPE等关键算法，并且在大模型领域有着深厚的技术积累。公司的名字来源于英国摇滚乐队Pink Floyd的专辑《Dark
Side of the Moon》，象征着对未知的探索和创新。

kimi是他们家智能助手的名字，真正的大模型是叫Moonshot。这一点我们从
API 的 model 参数中也能发现。因此后面谈到大模型时，就统一称呼为Moonshot。

Moonshot 这个名字可能取自 “登月计划”，可见他们的雄心壮志。公司取名 “月之暗面”，更是增添了几分神秘色彩。

API 设计

Moonshot 还有一点让魔法哥很有好感——它的 API 语法完全兼容 OpenAI。这意味着海量基于 GPT 的开源项目和商业项目都有极大可能在 Moonshot 上跑起来。

对于开发者来说，这也是一项巨大的优势。现有基于 GPT 的老项目都可以无缝接入 Moonshot，基于 Moonshot 的新项目也可以随时更换引擎。不管是迁移来还是迁移走都毫无压力！

开放平台

开放地址：https://platform.moonshot.cn/docs/docs

平台还为每个新用户赠送了15.00 元元的 API 调用额度。对于开发测试来说，足够用一阵子了。

创建 API Key

创建的Key记得保存，后面要用！！！

简介

传统php-fpm架构调用openai等大模型接口时只能做到阻塞调用，由于大模型接口返回速度很慢，一个php-fpm进程一分钟只能调用几次，几个人一刷系统就会明显的卡顿甚至不可用状态，所以php-fpm不适合做大模型调用，而webman这类的常驻内存类型的框架非常适合大模型应用的开发。

webman/openai 是一个异步非阻塞的openai客户端，配合webman可以做到同一时刻支持上万并发调用，使用简单，返回如丝般的顺滑，无卡顿。

安装

composer require webman/openai

安装该插件之前记得先安装webman框架。
