A developer set up a Xiaomi 12 Pro (Snapdragon 8 Gen 1) as a headless, always-on local AI inference server running Ollama with Gemma 4, hitting 216 upvotes and 66 comments on r/LocalLLaMA. The build demonstrates that flagship-tier mobile hardware from 2022 can serve as a dedicated local inference node, running 24/7 with acceptable performance. This follows the broader trend of creative edge-device inference — last week featured a bare-metal UEFI inference build — as practitioners seek zero-cost, always-available local AI.
