Rate Limiting
云服务和API领域的标准技术手段，用于防止系统过载和滥用，在AI订阅产品中以每分钟请求数、每天任务数或每月token消耗上限等形式呈现

A common implementation of rate limiting and sliding window throttling involves recording a user's request volume or compute consumption within a fixed or sliding time window and triggering a cooldown when the threshold is exceeded.
The core logic of rate limiting is to restrict the number of requests from a single account or IP within a fixed time window
Rate limiting refers to providers setting upper limits on the number of requests or token consumption per unit of time to manage server load and computational costs.
当请求超出预设的RPM或TPM时，服务端会返回HTTP 429（Too Many Requests）状态码
当API请求超出预设的RPM或TPM限制时，服务端会返回HTTP 429（Too Many Requests）状态码
API异常中网关速率限制返回429错误，负载均衡器在后端不可用时返回502/503错误，GPU内存不足可能导致请求终止
When an API returns a 429 (quota exceeded) or 5xx (service error) status code, the routing layer can capture the signal and resubmit the request to the next provider in the chain.
