You can use the OpenAI GPT-3 API for a variety of tasks that require understanding or generating natural language or code. It provides an easy-to-use “text in, text out” interface so you can start using it on any English language task right away. Some applications include: semantic search, sentiment analysis, content generation, translation, summarization and classification. The API is powered by several models with varying capabilities and costs; these include Davinci, Curie, Babbage and Ada (the base GPT-3 models) as well as Codex series which has been trained on both natural language and code processing.
