I used Qwen 27b 8 bit MLX version on a decompiled android APK recently. It succesfully identified how it worked even the obfuscated classes and methods. It wrote a 1000 line documentation with examples but the time was dreadful. At some point it slowed down to 5 t/s so the whole thing took over an hour , the writing of documentation alone was over 40 minutes, fans blasting the entire time.
