OpenAI Codex CLI#6

OpenAI's official open-source terminal agent featuring secure sandbox execution and GPT-5 reasoning models.

OpenAI Codex CLI brings OpenAI's frontier models straight to the local terminal. Operating inside a sandboxed execution layer with adjustable approval thresholds, it modifies source files, executes test suites, and offloads heavy background builds to OpenAI cloud VMs. It is included natively for ChatGPT Plus and Pro subscribers.
