ChatGPT Pro 5x costs $100/mo; Kimi Allegro costs $99/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.
ChatGPT Pro 5x vs Kimi Allegro: choose ChatGPT Pro 5x. ChatGPT Pro 5x costs $100/mo; Kimi Allegro costs $99/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score. The two plans are compared on what a week of real coding tasks fits, not on a feature list.Measured
Our verdict
Choose ChatGPT Pro 5x. It gives you every OpenAI model and a clear coding product. Kimi Allegro charges almost the same for a model that has gone backwards in our use.
Kimi still has good visual instincts, but its credit burn makes it impossible to recommend.
$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.
How far it goes: we have not measured this plan
Same Codex CLI as ChatGPT Plus with five times its allowance - the Plus scorecards are the closest evidence.
$99 gives K3 five times the agent credits of Allegretto. The usage limit still runs out too quickly. K3 has regressed in our use since release. More credits do not make it worth buying.
Pros
Five times the Allegretto agent credits
Good visual design
Cons
The usage limit drains too quickly
K3 has regressed since release
Best for Nobody.
