ChatGPT Pro 20x costs $200/mo; Kimi Vivace costs $199/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.
ChatGPT Pro 20x vs Kimi Vivace: choose ChatGPT Pro. ChatGPT Pro 20x costs $200/mo; Kimi Vivace costs $199/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. It gives you every OpenAI model and a coding product that is easier to trust and follow.
Kimi Vivace costs almost the same, empties its limit too fast, and runs a model that has got worse in our use.
$200 gives Codex one weekly usage bucket with no 5-hour session window. It has four times the allowance of Pro 5x. You get every OpenAI model, including Astra. Buy it only if the Pro 5x weekly limit is blocking your work.
Pros
No 5-hour session window
Four times the Pro 5x allowance
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 Pro 5x weekly limit.
How far it goes: we have not measured this plan
Same Codex CLI as ChatGPT Plus with twenty times its allowance - the Plus scorecards are the closest evidence.
$199 gives K3 ten 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
The largest Kimi credit pool
Good visual design
Cons
The usage limit drains too quickly
K3 has regressed since release
Best for Nobody.
