Frequently asked questions
Which is cheaper?
In practice they tie: both ship inside subscriptions from about $17-20 a month (Claude Pro and ChatGPT Plus). The real cost appears under intensive use, where each plan's limits and the jump to higher tiers set the bill.
Which works better on its own?
On long, ambiguous tasks over real repositories, Claude Code holds the more consistent reputation. On bounded, parallel tasks, Codex's cloud agents are especially convenient.
Can I use both?
It is a common combination: same repository, each agent for what it does best. Both have CLIs and fit the workflow without getting in each other's way.
