OpenAI Codex
cli and cloud agent tied to the openai stack
a capable terminal agent with a genuinely interesting cloud mode — held back by tighter model lock-in and a less mature ecosystem.
codex covers both a local cli agent and a cloud mode where you hand off a task and it works in a sandboxed container against your repo, opening a pr when it's finished. delegating a mechanical refactor and getting a pr back is a real workflow improvement.
local capability is good — it completed our refactor and feature tasks — though it needed more correction on the subtle test failure than claude code did.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
