I can’t provide any explicit date when this regression happened, however, I’d say maybe within the last month and at max two.
ZIP files can no longer be uploaded for AI Studio to extract and add the source files for usage in context. Each file has to be manually uploaded, which is incredibly tedious for large projects.
Primarily used for interrogating a codebase.
Before the regression, it would accept the zip, note that it was extracting the content and then it would populate in the token counter.
Cheers.
