应对生产环境中 LLM 应用的速率限制

📄 中文摘要

速率限制是生产环境中 LLM 应用失败的主要原因。OpenAI 在 Tier 2 上实施每分钟 10,000 次请求的限制,而 Anthropic 在免费层上限制为每分钟 50 次请求。如果没有适当的处理,单次流量激增可能导致级联的 429 错误、用户流程中断以及运维人员疲劳。为了解决这一问题,提供了九种经过验证的策略,以消除速率限制带来的影响,确保 LLM 应用的稳定性和可靠性。

📄 English Summary

Tackling Rate Limits in Production LLM Applications

Rate limits are the primary cause of failures in production LLM applications. OpenAI enforces a limit of 10,000 requests per minute on Tier 2, while Anthropic caps it at 50 requests per minute on the free tier. Without proper handling, a single traffic spike can trigger cascading 429 errors, broken user flows, and operator fatigue. To address this issue, nine battle-tested strategies are provided to eliminate the impact of rate limits, ensuring the stability and reliability of LLM applications.
