# Model and Rate Limit

This page lists all the models currently supported by the Xiaomi MiMo API Open Platform, including model capabilities, length limits, and rate-limiting quotas, to help you select the appropriate model based on your usage scenario. 

### Rate Limiting Instructions

The platform sets a model concurrency limit for each account. When the server load is high, response delays or ` 429 ` error may occur. We recommend that you reasonably plan your request frequency and implement request retry and backoff strategies in high-concurrency scenarios to avoid triggering rate limits.

- **RPM (Requests Per Minute)**: The maximum number of requests initiated per minute. The calculation scope is the sum of the total number of requests from all API Keys under a single account when calling the same model.
- **TPM (Tokens Per Minute)**: The maximum number of Tokens that can be interacted with per minute. The calculation scope is the sum of the total number of requested Tokens for all API Keys under a single account when calling the same model.
