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.

OpenAI

ChatGPT Pro 5x

$100/mo per chatgpt.com/pricing, 2026-08-12

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.

Moonshot AI

Kimi Allegro

$99/mo per kimi.com/pricing, 2026-08-12

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.
