The Codex agent loop is a component of OpenAI's Codex technology that enables users to interact with large language models. The loop involves a series of steps where the user provides input through the Codex CLI, which then orchestrates the model, tools, and prompts using the Responses API. This process allows for efficient management of model performance and output. According to the OpenAI website, this technical deep dive aims to explain how the Codex agent loop works in detail. --- Why it matters: Understanding the Codex agent loop is crucial for developers who want to integrate OpenAI's language models into their applications or tools, as it provides insight into how to effectively manage model performance and output.
