错误翻译

原文：Your requests to dall-e-3 for dall-e-3 in East US have exceeded the call rate limit for your current OpenAI S0 pricing tier.
译文：您在（美国东部区域）向 dall-e-3 发出的请求已超出当前 OpenAI S0 定价层的调用速率限制。

原因分析
此错误是调用速率限制，根本原因是短时间内向 Azure OpenAI 的 DALL-E 3 API 发送了过多的请求。服务端对每个定价层级（如 S0）都有每分钟/每秒钟的请求上限，本次请求 ImageGenerations_Edit 时触发了这个限制。

解决方案
主要解决方法是实现请求间隔和重试逻辑，避免触发速率限制。
