[尝鲜] AIGC and Chatgpt

March 24, 2023 Architect, system No comments

属于Chatgpt的“iPhone”时刻来了,伴随着越来越多的模型能力放出,AIGC的场景越发丰富以及明朗,越来越多的业界大神也亲自下场操盘,投资界即将迎来一场技术的历史变革,各方都期待能瓜分到这巨大蛋糕的一角。今天我们就来浅尝一些功能性的应用。。。

OpenAI刚刚宣布推出插件功能,赋予ChatGPT使用工具、联网、运行计算的能力  Chatgpt-plugin

1、昨天该机构开放了第一批 ChatGPT 插件名单。这批插件由 Expedia、FiscalNote、Instacart、KAYAK、Klarna、Milo、OpenTable、Shopify、Slack、Speak、Wolfram 和 Zapier 创建

 

例如,将Wolfram通过插件形式,加载至会话过程中 ,具体见chatgpt-gets-its-wolfram

同时 openai还公布了查询自有知识库和文档库的接口 ChatGPT Retrieval Plugin

 

2、提示工程(Prompt Engineering)这个概念最近被提出,并诞生了多家初创公司,Prompt的原意就是提示、驱使的意思,只不过提示、驱使的对象有点特殊,不是人类,而是类似ChatGPT这样的AI。PromptBase、Krea、PromptHero 、 Promptist 等一些提示词买卖平台已经出现,以下以dall-e-2为例,演示AI作图

 

1) a cat running on the grassland

 

 

2) a very very cute cat running on the grassland

 

 

3) a  beautiful painting of a mountain next to a waterfall

 

 

4) a very very very very very very very very very very beautiful painting of a mountain next to a waterfall

 

 

可以看到,不同的描述,出现的画质还是有区别的,这就是PromptBase的意义,建立一个专业/非专业通道(promptbase建立一个公平交易平台,促成提示词买卖的达成),也算是一种新的商业模式了,可以看到PromptBase网站确实提供了非常多专业的绘画。

 

AIGC的领域远远不止绘画,包括与chatpgt师出同门的 Jasper AI ,可以编写多种博文、脚本、社交媒体帖子等各种类型的文案,Stable Diffusion 、Imagen 、Dall-E、Midjourney 都是能通过文本,直接生成图像的AI应用。

 

当然也包括微软最近推出的Office重磅功能Coplit 以及Github的 Coplit X
