Mace-cl-compiled-program.bin

The file serves one of three primary roles depending on the exact SoC generation:

scp mace-cl-compiled-program.bin user@raspberrypi:/home/user/model/
ssh user@raspberrypi
cd /home/user/model
./my_mace_app --program mace-cl-compiled-program.bin

Apps that have bundled such files include: mace-cl-compiled-program.bin

In those apps, you might find a path like:
/data/data/com.xiaomi.aicamera/files/mace_models/segmentation/mace-cl-compiled-program.bin The file serves one of three primary roles

mace-cl-compiled-program.bin is not malware. It is not spyware. It is evidence of smart engineering. Apps that have bundled such files include:

By caching compiled OpenCL binaries, Xiaomi’s MACE framework turns a computationally expensive JIT compilation step into a near-instant load operation. For the average user, this means their camera filters apply instantly, their photo editor runs smoothly, and their AI keyboard predicts the next word without stuttering.

For the developer, it represents a trade-off between storage space and latency. For the forensic analyst, it is a breadcrumb revealing which neural networks were run on a device.

Bottom line: Do not delete it unless you have to. And if you do—do not worry. The app will simply rebuild it, and you will suffer exactly one slow launch before the magic of the binary cache restores your performance.
