SDXL model optimized for iPhone by managing iOS memory pressure

A developer has detailed the challenges of running the SDXL image generation model on an iPhone, primarily due to iOS memory pressure. The key issue was preventing the operating system from terminating the process mid-generation, which was resolved by serializing the initialization of model components to avoid memory spikes. This approach ensures the model stays within iOS limits, though older devices still have a very thin margin for error. AI

    Getting SDXL to run on an iPhone without iOS killing the process mid-generation

    <!-- SC_OFF --><div class="md"><p>I spent a while getting Stable Diffusion working through Core ML on the Neural Engine, and the actual model was never the hard part, memory pressure was.</p> <p>SDXL on a phone sits right at the edge of what iOS allows before the OS jetsams you. …
