The End of Cloud Inference (docs.google.com)

The article argues that the future of AI inference is moving offcloud and onto personal devices: phones, laptops, and desktops will increasingly run models locally rather than sending every request to distant data centers. This shift is driven by economics (per‑request cloud costs vs. essentially free local runs after hardware purchase), latency, privacy, reliability, and the growing capability of on‑device models and toolchains. Apple’s progress — a unified memory architecture that lets large models fit and run more efficiently, plus the MLX toolkit for deploying and optimizing models on Macs and iPhones — makes practical on‑device inference a present reality. Real examples like Stable Diffusion running offline on a Mac demonstrate that compelling AI workloads no longer require warehouse‑scale GPUs. For developers and the AI ecosystem this has big technical and commercial implications: lower marginal serving costs enable one‑time purchases, generous free tiers, and riskier innovation; apps can default to local inference and only escalate to cloud hosts for rare, heavyweight tasks (larger models or massive knowledge bases). Technically, unified memory and optimized runtimes plus advancing open‑source models expand the feasible model sizes and latency profiles for edge inference. The cloud won’t vanish — it remains essential for storage, coordination, and frontier compute — but the “default” locus of everyday AI will increasingly be the device where the data lives, upending per‑request business models and potentially stranding some data‑center capex assumptions.
