Our verdict
Choose Claude Max 5x. Both plans cost $100. Claude gives you Opus 5.5 with room for several agents, plus Fable for the hardest problems. ChatGPT Pro 5x only adds allowance to the same Codex models.
If you are willing to spend $100 on a coding agent, Claude settles this comparison.
$100 gives Opus 5.5 five times the Pro allowance. Opus 5.5 is light enough on the limit to keep several agents running through the day. Fable is included for the hardest planning, but Opus 5.5 now covers most of it. Move here when the Pro limit stops you.
Pros
Five times the Pro allowance
Room for several Opus 5.5 agents
Sonnet 5.5 for smaller things and simple tasks
Fable for the hardest planning
Cons
Pro covers most single-agent days for $80 less
Best for People who keep hitting the Claude Pro limit. Start on Pro first.
How far it goes: at least 15 times a week, and more than 100 for the cheapest model
Our whole real-world issues and spec planning pass runs at least 15 times a week, and more than 100 for the cheapest model on this plan, depending on which model you run.
That works out at about under 23c to $1.84 of the subscription per run, at the list price.
Measured on this plan, at <1% to 8%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
$100 gives Codex one weekly usage bucket with no 5-hour session window. You get every OpenAI model, including Astra. Buy it only if Plus's 5-hour windows are blocking you from doing more work.
Pros
No 5-hour session window
Every OpenAI model, including Astra
Luna for high-volume small tasks
Cons
No Opus 5.5 or Fable
Best for Codex users blocked by the Plus 5-hour windows.
