Models
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.
