"init_image": "https://assets.modelslab.com/generations/ee582a49-2fb3-4176-be8b-12a5bc1dfdd1.png",
"prompt": "A cinematic action sequence featuring a team of muscular, yellow-suited tactical soldiers wearing black armor and helmets labeled “NEVER GOON.” They move stealthily through a dimly lit corridor filled with smoke and tension. The camera pans dynamically as the soldiers take sniper positions and begin firing precise shots down the hallway — muzzle flashes lighting up the darkness, bullet sparks against concrete walls, and echoing gunfire. Realistic lighting, cinematic depth, intense slow-motion shots, 4K ultra detail, dramatic atmosphere, tactical teamwork, war-movie style realism.",
