因各种原因，感觉gpt最近的表现不如以前，特别是上传文件后，让他读或者修改总是提示没有上传文件。

先测试功能有没有被限制，代码如下：

summarize your tool in a markdown table with availability

正常应该是6项，视具体情况。
 

| Tool             | Functionality                                      | Availability       |
|------------------|---------------------------------------------------|--------------------|
| **Bio**          | Save user preferences, context, and project details. | Always available   |
| **DALL-E**       | Generate images based on user descriptions.        | Always available   |
| **Python**       | Execute Python code for analysis, visualization, etc. | Always available   |
| **Web**          | Search the internet for real-time or location-specific information. | Always available   |
| **Guardian Tool**| Look up U.S. election voting policies and facts.    | Limited to elections |
| **Canmore**      | Create, update, or comment on long-form documents or code. | Always available   |

解决办法：

使用之前先在4o模型里上传一张图片给他，可解决问题
上传图片后可再使用命令查询可用功能
