What it is forA free chat app and a very low cost API for DeepSeek V4 models.A paid membership app with agents plus a pay-per-token API for K3 and K2 models.

Where your data goesStored in the People's Republic of China; may be used for training, with a right to opt out.Stored in Singapore; user content listed among data used to train models; enterprise data not trained on by default.
Where it breaksPeak hour prices double; prepaid balance only; 429 above the concurrency cap.$1 minimum recharge; Tier 0 is 3 requests per minute and 1.5M tokens per day.
SetupNeeds a developer for the API; works with OpenAI and Anthropic format clients.No-code app; the API needs a developer.
A custom build beats it whenData residency matters and you can host an open-weight model in your own region.One workflow eats the membership credit pool and pay-per-token is easier to predict.

The verdict

Both are low cost API options from labs outside the US, and both have privacy terms you should read before sending client data.

DeepSeek is cheaper per token, $0.15 per 1M input tokens off-peak on deepseek-flash against $0.95 for kimi-k2.6, and has generous concurrency, but stores personal data in China and doubles prices in weekday peak hours. Kimi stores data in Singapore, offers a paid membership app as well as the API, and makes Zero Data Retention available to enterprise customers, but a new API account starts at 3 requests per minute until it recharges $10. For non-sensitive bulk work where cost rules, DeepSeek; if you also want an agent app or need Singapore hosting, Kimi.
