ChatGPT Pro 5x vs Kimi Allegro
ChatGPT Pro 5x is for heavy Codex users committed to the OpenAI stack; Kimi Allegro is for daily use of an open-weight model you already like. ChatGPT Pro 5x costs $100/mo, 1x Kimi Allegro's $99/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 Moonshot AI ladder. Every Kimi tier runs the same open-weight K3 on the same credit mechanics, and the rungs are credit multiples of the $19 tier (roughly 2x, 5x and 10x its allowance). Pick a rung by how much you will use; the model is identical everywhere.

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
Same Codex CLI as ChatGPT Plus with a much bigger allowance - the Plus scorecards are the closest evidence.

The right tier for a daily Kimi habit, arriving at the wrong moment. Five times the credits sounds like the fix, but the thing that changed is the model: K3 does less than it did, and $99 of a weaker model is still a weaker model.
Pros
- Five times the entry-tier credits
- Enough allowance for daily use
Cons
- Buying volume does not fix the model
- Heavy use still burns credits quickly
Best for Daily use of an open-weight model you already like.
