Our verdict
This matchup is no longer about price: Kimi's plan costs $19 and ChatGPT Plus $20. Kimi wins on two specific fronts, the uncapped free tier and the million-token context for document work. ChatGPT wins on everything else: voice, images, ecosystem and a more mature product. And if you handle client data, Kimi's policy never says which country stores it.
Frequently asked questions
Wasn't Kimi the cheap option?
It was: with K3 its plans landed within a dollar of ChatGPT's or Claude's. The real discount now lives in its free tier, which survives daily use with uncapped basic chat.
Which is better for long documents?
Kimi, on context window: a million tokens against ChatGPT's considerably lower limits. The catch is that the full context only unlocks on its higher plans.
What about data in Kimi?
Its policy admits using conversations for training and never states which country stores the data. For personal use that is a factor to weigh, for client or regulated data it is a dealbreaker.
