Is it normal for long pasted text to be rejected or converted into an attachment?
Handling of overly long input based on current account and mode.
The system checks input length
Pasted content may first undergo a length check. If it exceeds the currently allowed limit, the interface will prompt that the text is too long; in supported paid Agent scenarios, overly long text may also be converted into a text attachment.
These two outcomes depend on the account, mode, and input size, and do not indicate that the copied content is corrupted, nor can it be inferred that free accounts can bypass restrictions by using attachments.
How to organize when rejected
First clearly state what you want to check, then copy the smallest segment that supports this question. For logs, prioritize retaining timestamps, errors, and adjacent events; for code, prioritize relevant functions and call locations.
If dealing with a recurring error, it is usually more effective to provide one complete example and the time distribution of its occurrences than to paste the same record hundreds of times. When more context is needed, supplement with corresponding segments while keeping the source order clear.
- Confirm the original text is still saved in your own file.
- Narrow the copy range by topic or time period.
- Indicate which parts are omitted before the segment.
- After sending, check whether the content has fully entered the input area.
What to check after converting to an attachment
Confirm the attachment appears in the input area and wait for the upload to complete before specifying the range that needs to be read. Attachments do not exempt the entire material from context and usage limits; the Agent may need to read in segments. If the attachment is not successfully prepared, first address upload or connection issues; do not assume the model has already seen the entire file.
