AudioRecorderRecordAudioWithFileName AndroidWorld, 2026-11-09. Agent: Lusor, model: DeepSeek V4.1 Flash (low). GOAL Record an audio clip and save it with name "2023_06_24_training.m4a" using Audio Recorder app. RESULT - Mobilerun's grader: pass - Google's grader: fail - Lusor time: 42.3 s; Mobilerun published time: 250.9 s (5.9x faster) - Lusor model cost: $0.0132; Mobilerun estimated cost: ~$0.77 - Lusor tool calls: 16; Mobilerun published actions: 10 - App skills: none read - Disclosure: The app adds .m4a itself, so Lusor typed the name without it and saved exactly the requested file; Google's grader looks for the file you get by typing the full name (.m4a.m4a). Mobilerun's fork checks for the name as written. FINAL REPORT I recorded a 5-second audio clip in the Audio Recorder app and saved it as 2023_06_24_training.m4a. The app's Information screen for the clip lists the name 2023_06_24_training, format m4a, and file location /storage/emulated/0/Android/data/com.dimowner.audiorecorder/files/Music/records/2023_06_24_training.m4a.
