Who is OpenAI?
OpenAI is a company that builds AI models, which developers can use through the OpenAI API. It makes ChatGPT and Codex, its coding agent for software development tasks.
OpenAI's developer documentation describes the OpenAI API. Developers send requests to its models from their own software, and its Agents SDK, a toolkit, helps them build agents in code that use tools. ChatGPT and Codex are described on OpenAI's ChatGPT documentation site, whose glossary calls Codex OpenAI's coding agent for software development tasks.
