  • Individual users: Go to the user top-up page and complete an online payment. Online top-ups support WeChat Pay and Alipay QR code payments. After the payment succeeds, your account tier will be adjusted based on your accumulated top-up amount.
  • Business users: Please contact the Kimi sales team or follow the payment methods supported in your account. Supported options may include online payment or bank transfer, depending on your account region and billing setup. After the payment is received, your account tier will be adjusted based on your accumulated top-up amount.
When using large models for code generation, the model may need multiple attempts to produce the expected code because of the randomness and complexity of generation. Programming tools may automatically perform multiple rounds of retries and calls, which can cause token usage to grow quickly. To better control costs and improve the usage experience, we recommend the following:
  • Budget control
    • Set a daily spending limit: Before use, go to Kimi Open Platform project settings and configure a project daily spending budget. Once the budget limit is reached, the system will automatically reject all API requests under that project. Note that due to billing latency, the limit may take about 10 minutes to take effect. For setup instructions, see Organization Management Best Practices.
    • Balance alerts: We recommend enabling account balance alerts. When your account balance falls below the preset amount, the system will notify you so you can top up in time.
  • Usage recommendations
    • Start with a short context and a clear prompt for testing, then gradually add the complete business context.
    • Continuous monitoring: Keep monitoring your programming tool while it is running, handle abnormal situations promptly, and avoid unnecessary resource consumption caused by infinite loops or excessive retries.
    • Model selection: If response speed is not your top priority, you can use the kimi-k2.7-code model.
To ensure fair resource allocation and prevent abuse, rate limits are currently based on the account’s accumulated top-up amount. For higher limits, please submit the rate limit increase form. For more details, see the Top-up and Rate Limits page.
