ChatGPT Plus vs Claude Pro
ChatGPT Plus is our pick of the standard band. Both cost the same $20/mo.
Our verdict
The OpenAI ladder. Every paid ChatGPT rung runs the same Codex CLI and the same GPT 5.6 models; upgrading changes the weekly allowance and nothing else. Plus is already the lightest quota burn we measure, about 3% of its window per real-world run, so the upper rungs sell headroom most people never touch.
The Anthropic ladder. Every Claude plan is Claude Code on the same 5-hour rolling window, and a bigger rung buys a bigger allowance. The exception is Fable, which ships only on the Max tiers, so $20 buys Opus 5 and Sonnet 5 rather than the flagship. Our paired runs put the real 5x-to-20x gap nearer 5.7x than the advertised 4x.
ChatGPT Plus is our pick of the standard band.
ChatGPT Plus is for steady everyday use where headroom matters more than raw capability; Claude Pro is for writing and daily focused blocks, when coding is not the main job.
Both cost the same $20/mo.
We have not measured Claude Pro on its own plan; its card below points at the closest graded evidence.
None of the GPT 5.6 models is the one we would pick on capability alone. What Plus has is the meter: one real-world run costs about 3% of the weekly window, the lightest burn we measure anywhere, so the limit is never what stops you. This is the plan where you stop thinking about quota.
Pros
- One run costs ~3% of the weekly window, the lightest burn we measure
- Three GPT 5.6 models to switch between
- The quickest medians in the field
Cons
- The models sit mid-field, not at the front
- Headroom is the whole pitch
Best for Steady everyday use where headroom matters more than raw capability.
How far it goes: about 30 to 40 times a week
Our whole Real-world issues suite runs about 30 to 40 times a week on this plan, depending on which model you run.
That works out at about 11c to 16c of the subscription per run, at the list price.
Measured on this plan, at 2.4% to 3.5%/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.
The plan people buy for Fable does not include Fable - it ships on the Max tiers only, so $20 buys Opus 5 and Sonnet 5. That changes the answer: on our hardest work Opus sits behind Codex's Sol, which costs the same $20 and burns a fraction of the window. What Claude Pro still wins on is rhythm - the 5-hour rolling window is back by lunch, not next Tuesday - and everything that is not coding.
Pros
- The 5-hour window refills the same day, not weekly
- The best writing and thinking assistant at $20
- Same window mechanics as the Max tiers
Cons
- No Fable: the model the ladder is famous for starts at $100
- Opus 5 trails Sol on our hardest real-world tasks
- You will meet the allowance, and the promotion propping up its value will end
Best for Writing and daily focused blocks, when coding is not the main job.
How far it goes: we have not measured this plan
The Max 20x scorecards are the closest evidence, minus Fable: that model is Max-only, so the best agent this plan can run is Opus 5.
