报错分析报告

1.错误翻译


原文：Your input exceeds the context window of this model. Please adjust your input and try again.
译文：你的输入超出了该模型的上下文窗口限制，请调整输入后重试。

2.原因分析

根本原因：调用AI模型API时，输入内容（含prompt+上下文）的长度超过了模型支持的上下文窗口上限。

发生位置：错误源于OpenAIResponsesLanguageModel$2.doStream阶段（向模型发送请求时），具体是Cherry Studio中调用DMXAPI的输入过长。

3.解决方案

javascript
// 修复思路：调整输入长度（二选一）
const MAX_CONTEXT = 4096; // 替换为模型实际支持的上下文长度（如gpt-3.5-turbo为4096）
// 方案1：截断超长输入（优先保留核心内容）
let input = "你的原始长输入";
if (input.length > MAX_CONTEXT) {
  input = input.slice(0, MAX_CONTEXT); 
}// 方案2：拆分输入为多段请求（需业务层合并结果）
const inputChunks = [];
for (let i = 0; i < input.length; i += MAX_CONTEXT) {
  inputChunks.push(input.slice(i, i + MAX_CONTEXT));
}
// 逐段调用API（示例用伪代码）
inputChunks.forEach(chunk => callApiModel(chunk));

4.️ 预防措施

长度预检查：调用API前计算输入总字符数（含历史对话），确保≤模型context_window参数（查模型文档）。

工具辅助：用VS Code「Character Count」插件或代码内input.length校验，提前拦截超长输入。

---
注：需根据所用模型的实际上下文限制（如GPT-4为8k/32k）调整MAX_CONTEXT值。
