PDF recognition issue when using reseller's GPT-5.5 API in Cherry Studio

Context

Environment: Using reseller Codex with GPT-5.5 API, provider type selected as OpenAI

Problem: When attaching a PDF document and asking the model to read and summarize it, the model cannot recognize the uploaded document—it only recognizes the filename. The response is approximately: "You haven't uploaded a document, I'll search for the keyword... (the filename of my uploaded document)"

Potentially useful information: I then conducted comparison tests:

• When I continue using the same reseller's GPT-5.5 with attached images and ask it to read and recognize them, it works normally;

• When I use KIMI's official KIMI K2.5 with attached PDF documents and ask it to read and summarize, it recognizes them normally

在Cherry studio 中接入中转商的 GPT-5.5，在对话中其无法识别 PDF 的问题

Context

环境：接入中转商的 Codex 用 GPT-5.5 API，提供商类型选择的是 OpenAI

问题：当附加PDF文档，同时对话要求其阅读总结文档时，其会无法识别到我上传的文档，仅识别到我所上传文档的文件名。其大致回复您没有上传文档，我为您搜索关键词...（我上传文档的文件名）

可能有用的信息：随后我做了对比测试

• 当我在对话中继续使用该中转商的 GPT-5.5 附加图片，同时对话要求其阅读识别图片时，其正常识别；

• 当我在对话中使用 KIMI 官方的 KIMI K2.5 附加PDF文档，同时附加对话要求其阅读总结文档时，其正常识别
