The author spent $266 on four AI models to gain full control of their Amazon Fire HD tablet, which was shutting down due to Amazon's software. The AI models, including Kimi K3 and GLM-5.3, worked together to find and exploit a vulnerability in the tablet's kernel, eventually allowing the author to uninstall Amazon's packages and gain root access. The process took several days and required the author to prompt and guide the AI models. The author notes that the experience was educational and fun, despite the cost.
