OpenAI has recently released GPT-4 (a.k.a. ChatGPT plus), which is demonstrated to be one small step for generative AI (GAI), but one giant leap for artificial general intelligence (AGI). Since its official release in November 2022, ChatGPT has quickly attracted numerous users with extensive media coverage. Such unprecedented attention has also motivated numerous researchers to investigate ChatGPT from various aspects. According to Google scholar, there are more than 500 articles with ChatGPT in their titles or mentioning it in their abstracts. Considering this, a review is urgently needed, and our work fills this gap. Overall, this work is the first to survey ChatGPT with a comprehensive review of its underlying technology, applications, and challenges. Moreover, we present an outlook on how ChatGPT might evolve to realize general-purpose AIGC (a.k.a. AI-generated content), which will be a significant milestone for the development of AGI.

OpenAI最近发布了GPT-4（也称为ChatGPT plus），它被证明是生成AI（GAI）的一小步，但对于人工智能（AGI）来说是一大步。该研究对ChatGPT进行了全面的技术、应用和挑战的综述，并展望了ChatGPT未来如何实现通用AIGC（即AI生成的内容），这将是AGI发展的重要里程碑。
