Claude Max 5x vs ChatGPT Pro 5x
Claude Max 5x is our pick of the heavy band. Both cost the same $100/mo.
Our verdict
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.
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.
Claude Max 5x is our pick of the heavy band.
Claude Max 5x is for serious daily agent use without the top-tier price; ChatGPT Pro 5x is for heavy Codex users committed to the OpenAI stack.
Both cost the same $100/mo.
We have not measured Claude Max 5x on its own plan; its card below points at the closest graded evidence.
We have not measured ChatGPT Pro 5x on its own plan; its card below points at the closest graded evidence.
Half the price of Max 20x for the same models, harness and 5-hour rolling window, and for one person running one agent hard this rung clears most days. Worth knowing: our paired runs put the real gap between 5x and 20x nearer 5.7x than the advertised 4x, so the top rung buys more than its label says.
Pros
- The same models and window as the $200 tier
- Clears most days of serious agent work
- Half the price of the top rung
Cons
- Not enough headroom for several agents at once
- Same promotion caveat as the rest of the Claude ladder
Best for Serious daily agent use without the top-tier price.

This tier answers a question almost nobody on Plus is asking. Codex burns about 3% of the weekly window per real-world run, so the extra allowance solves a limit most users never hit, and the agent underneath is the same either way.
Pros
- Five times the Plus allowance
- Codex stays the quickest agent we measure
Cons
- Solves a limit most Plus users never hit
- The agent does not improve with the price
Best for Heavy Codex users committed to the OpenAI stack.
How far it goes: we have not measured this plan
