OpenRouter 上 “:batch” 后缀模型调用 chat/completions 报 cannot be used with the chat/completions endpoint
💡 模型列表里的变体后缀不都是别名,导入前要按后缀语义分类。
Problem
从 OpenRouter 模型列表批量导入模型到中转站后,带 :batch 后缀的模型 ID 在普通对话接口上全部报错。
Error (redacted / normalized)
deepseek/deepseek-v4.1-flash:batch cannot be used with the chat/completions endpoint (adapter DeepInfraBatchAdapter)
Applies when
OpenRouter 2026 模型列表;New API 或其他 OpenAI 兼容中转
Confirm it is this problem
curl -s https://openrouter.ai/api/v1/models | jq '.data[].id' | grep ':batch' → expect: 列表里有这些 id;对它们 POST /v1/chat/completions → 400 含 cannot be used with the chat/completions endpoint。
Not this when / boundary
如果是 :free、:nitro、:exacto 后缀,它们能走 chat/completions(只是路由不同),不要一并删除。
Root cause
:batch 变体只能走 OpenRouter 的批处理接口,不是 chat/completions 的别名。模型列表里它们和普通模型混在一起,导入时没区分。
Fix
- 从可用模型和 abilities 里删除所有
like '%:batch'的模型。 - 需要批处理再单独按 OpenRouter 的 batch 文档接入。
- 重启中转进程刷新内存里的模型缓存。
How to verify
GET /v1/models 不再含 :batch;原模型(无后缀)调用正常。
What did not work
给 :batch 模型加模型映射到无后缀 ID(客户端仍请求 batch ID)。
Risks
无。
