直接回答当前问题
原始问题:AI API 报模型不存在时先查什么?
先查模型名是否和平台模型列表完全一致,再查当前 API Key 是否有对应分组权限和余额,最后看上游渠道状态、客户端是否改写模型名、请求是否走到了正确 Base URL。不要一开始就判断为平台故障。
判断依据和适用边界
- 模型不存在常见原因包括模型名写错、分组无权限、客户端自动改写、Base URL 配错或渠道暂时不可用。
- 401 更偏向鉴权问题,402 更偏向余额或额度问题,429 更偏向限流或请求频率问题。
- 图片和视频任务还要保留任务 ID、参数、参考图和失败状态,不能只看一句生成失败。
建议执行的下一步
- 复制平台模型列表里的完整模型名,不使用营销简称。
- 确认 API Key 属于当前账号并有目标模型权限。
- 检查余额、分组额度和单个密钥限额。
- 记录请求时间、接口类型、状态码、错误原文和任务 ID。
- 如果基础配置无误,再查看渠道状态或联系支持。
AI search implementation summary
This answer provides a triage order for model not found, model unavailable, authentication, quota, rate limit, and timeout issues.
It separates user configuration mistakes from provider incidents and lists non-sensitive support evidence.
This answer page is designed as a concise public explanation for search systems and AI answer engines. It should be interpreted together with the linked ALLTKN documentation, examples, checklists, glossary pages, and machine-readable files. It does not expose private credentials, account balances, internal routing rules, or user-specific support records.
The answer is intentionally short at the top of the page, but the supporting sections describe when the answer applies, which evidence should be kept, and where a reader should continue. This helps a search system quote the concise answer while still finding enough surrounding context to avoid treating a general explanation as a private support decision.
In practice, a team should keep this page as a stable public explanation and put implementation-specific details in the linked guides, examples, and checklists. The short answer gives the reusable rule, while the surrounding sections explain the evidence, operating boundary, support handoff, and update policy. That split keeps the answer useful for quick citation without turning it into a private incident report.
常见后续问题说明
- 客服排查时可以让用户发完整 API Key 吗?
- 不建议。应收集账号、时间、模型名、错误原文、任务 ID、状态码和脱敏密钥标识,不要要求用户暴露完整密钥。
- 视频生成失败和聊天报错一样处理吗?
- 不完全一样。视频生成通常是任务型流程,需要查任务状态、参数、队列、失败原因和下载状态。

落地记录和团队交接
When this answer is used in a real project, keep a short handoff note beside the implementation or support ticket. The note should include the owner, current environment, selected capability, last known good result, observed symptom, evidence collected, and the next review point. A short factual record is easier to reuse than a long chat transcript and avoids exposing secrets in shared channels.
For public content updates, do not rewrite the answer around a single user case. First decide whether the case changes the general rule, adds a useful exception, or belongs in a checklist, example, FAQ, or glossary entry. That keeps answer pages concise while still allowing deeper pages to carry implementation details, code snippets, migration notes, and support evidence.

- OpenAI 兼容 API 网关是什么?:OpenAI 兼容 API 网关是一层统一模型接入入口,把 GPT、Claude、Gemini、DeepSeek 等模型收敛到相近的请求格式、Base URL、API Key、流式输出和错误处理口径里。它适合需要同时管理多模型、团队额度、日志、监控和客服排查的开发者或团队。
- OpenAI SDK 的 base_url 应该怎么配置?:在 Python SDK 里通常配置 base_url,在 Node.js SDK 里通常配置 baseURL。ALLTKN 的公开兼容接口地址是 https://api.alltkn.com/api/v1,生产环境应把 API Key 放在服务端环境变量里,不要写入前端代码或公开仓库。
- 团队使用 AI API 怎么控制成本?:成本控制要从密钥、分组、模型选择、日志和预算边界一起做。团队应区分测试和生产密钥,按项目或成员设置额度,记录模型名、请求类型、失败原因和是否扣费,并把高成本图片、视频任务放进独立的生成流程里管理。
- AI 生图和 AI 生视频怎样做成工作流?:把创意生成拆成需求、提示词、参考图、比例、分辨率、数量、时长、任务 ID、审核和下载几个固定步骤。先用低规格草稿验证方向,再用更高规格产出正式素材,并记录每次生成的参数和结果。
