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.

翻译：OpenAI近期发布了GPT-4（即ChatGPT plus），这被证明是生成式AI（GAI）的一小步，却是通用人工智能（AGI）的一大步。自2022年11月正式发布以来，ChatGPT迅速吸引了大量用户并引发广泛媒体报道。这种前所未有的关注度也促使众多研究者从各个方面对ChatGPT展开研究。根据谷歌学术数据，已有超过500篇论文在标题或摘要中提及ChatGPT。鉴于此，亟需一篇综述性文章，而我们的工作正填补了这一空白。总体而言，本文首次对ChatGPT进行系统调研，全面回顾了其底层技术、应用及挑战。此外，我们展望了ChatGPT如何演进以实现通用型AIGC（即AI生成内容），这将成为AGI发展的重要里程碑。
