Hugo van KemenadeWe got a human-submitted, AI-generated PR for @pillow that claimed to speedup an internal function by 54%.
It presented no benchmark script, so I benchmarked and found no noticeable improvement.
The PR claimed the "new optimized code was tested for correctness" and offered some "Generated Regression Tests" that it declared passed.
I ran them. After fixing an import error, the tests failed for both the PR and main.
No thank you, Codeflash AI.
