AI图像生成问题分类体系

使用API批量生成图片时，问题通常可以分为四大类别：技术性问题、质量性问题、效率性问题和成本性问题。每类问题都有其特定的排查方法和解决策略。

掌握问题分类是快速解决API调用问题的关键。正确的问题归类能够帮助我们快速缩小排查范围，避免无效的尝试，直接定位到最可能的解决方案。

批量API调用时，多个问题往往会同时出现，需要我们具备系统性的思维来逐一解决，并建立有效的预防机制。

图像生成问题诊断矩阵

以下是 AI图像生成问题 的系统化诊断框架：

🔥 问题排查通用流程

第一阶段：问题现象收集

在开始排查之前，系统收集问题信息至关重要：

• 错误信息记录：完整保存API返回的错误代码和描述
• 环境状态确认：检查网络连接、API密钥、账户余额
• 复现条件分析：记录问题出现的具体条件和触发因素
• 影响范围评估：确定问题是偶发性还是系统性

第二阶段：问题分类定位

根据症状表现，快速将问题归类到对应的类别：

• 技术性问题：通常有明确的错误代码，问题重现性强
• 质量性问题：生成能完成但结果不符合预期
• 效率性问题：功能正常但性能表现不佳
• 成本性问题：费用消耗超出预期或ROI不理想

分类问题解决方案

针对不同类别的问题，我们需要采用相应的解决策略：
