Codex Features & Product Lineup
About 5 minutes
Codex is OpenAI’s coding agent for writing, fixing, reviewing, and shipping code. It connects to a ChatGPT account and supports multiple entry points, from local development to cloud-based repository work.
This section organizes ChatGPT and Codex by four questions: which plan to use, which ChatGPT features to use, which Codex entry point to choose, and how to manage Codex in an organization. Pricing, usage limits, availability, and promotions can change, so check OpenAI’s official pages before making a purchase or rollout decision.
