简介

在这里，我们将建立一个多模态人工智能代理，它可以执行各种任务，包括文本到语音、从文本生成图像、描述图像和网络搜索。我们将利用 CrewAI 框架来协调一组专门的代理，每个代理都有自己的工具和能力。为了实现快速推理，我们将使用 Replicate AI 的模型在 Groq 硬件加速器上运行代理。

系统架构

系统将由以下组件组成：

1. CrewAI：用于定义代理、其角色、目标、工具和协作工作流。
2. Replicate AI：提供预先训练好的多模态语言模型，这些模型将支持代理根据文本描述生成图像和基于图像的问题解答。
3. Groq：这是一款快速人工智能推理工具，由 LPU™ 人工智能推理技术提供支持，可实现快速、经济、节能的人工智能。
4. Tavily-Python： 用于网络搜索和信息检索的开源库。

这些代理将组成一个团队，每个代理都有特定的角色和工具。他们将相互协作，在需要时相互授权，以执行多步骤任务。

代理角色和能力

1. 文本到语音代理

• 角色： 将输入文本转换为自然语音
• 工具：复制人工智能文本到语音模型
• 能力：将文本作为输入并输出音频文件
• 模型： cjwbw/seamless_communication

2. 图像生成代理

• 作用：根据文本描述生成图像 根据文本描述生成图像
• 工具：复制人工智能图像生成模型 复制人工智能图像生成模型
• 能力：将文本提示作为输入，并输出生成的图像
• 模型：xlabs-ai/flux-dev-controlnet

3. 图像到文本描述代理

• 作用：用自然语言描述图像内容 用自然语言描述图像内容
• 工具：复制人工智能图像标题模型、
• 能力： 将图像作为输入并输出文本描述
• 模型：yorickvp/llava-13b

4. 网络搜索代理

• 作用：从网络上检索相关信息，回答查询： 从网络中检索相关信息以回答查询
• 工具：Tavily-Python 网络搜索库
• 功能：将查询作为输入，输出相关信息摘要

工作流程实施步骤

1. 用户向代理发出指令。
2. 根据用户指令，路由器代理决定进一步的行动方案。
3. 根据路由器代理的回复，检索器代理通过调用相应的工具执行最终任务。
4. 如果路由器代理的响应是 “text2image”，则检索器代理将调用图像生成工具
5. 如果路由器代理的响应是 “image2text”，那么 Retriever Agent 将调用工具来描述图像。
6. 如果路由器代理的响应是 “text2speech”，Retriever Agent 将调用工具将文本转换成音频。
7. 如果路由器代理的响应是 “web_search”，Retriever Agent 将调用网络搜索工具生成响应。
