OpenAI Codex

What it is

Cloud-based software engineering agent platform from OpenAI for delegating coding tasks, reviewing changes, and operating across repository workflows.

In Choosely terms, this sits in the coding & app building lane and is commonly selected for cloud-based engineering agents and delegated coding tasks.

Pricing

Codex pricing varies by ChatGPT plan, workspace migration status, model, fast-mode usage, and token consumption. Most current plans use token-based Codex credits; a small subset of Enterprise customers may still use the legacy rate card.
