# Codex Details

Codex is OpenAI’s coding agent for the terminal, and the CLI is open source under Apache 2.0. It is one surface of the wider Codex product, which also spans an IDE extension, cloud environments, the web, and iOS.

## models and pricing

Codex defaults to GPT-6.1 Sol and switches models with `/model`; the lineup depends on your plan. Sign in with a ChatGPT account on any plan from Free to Pro (from $100/mo) with credit-based usage, or sign in with an API key and pay standard token rates. Its config also accepts custom model providers, and `--oss` runs local open-source models through Ollama or LM Studio.

## what it’s good at

Codex pairs OS-level sandboxing with granular approval and permission modes, so risky commands stay gated. `codex cloud` hands tasks to cloud environments and includes a dedicated code-review mode. AGENTS.md project instructions, skills, slash commands, lifecycle hooks, and MCP support round out the same extension surface its competitors are converging on.
