和詹同学一起回顾了OpenAI首次Dev Day，简直是一次里程碑式的发布了！

OpenAI完整的呈现了它的野心和路径：chatbot -> AI Agent -> AGI，并且坚定的产品化的不断实践

在竞争对手还在做chatbot的show cases时，OpenAI已经完整展开了两个生态：一个是ChatGPT+GPTs，以chat为核心交互的全新体验；一个是以Assistants API为核心的能融入现有任何产品形态做AI+的模式

目前GPTs及GPT Builder都已对订阅用户开放，来体验下我做的小东西吧：https://chat.openai.com/g/g-O8VXL4opJ-emoji-sparkles
