Microsoft Shifts AI Strategy Toward Local Inference with Phi Silica

At Build 2024 on May 21, Microsoft announced Phi Silica, a small language model optimized for Copilot+ PCs, and Phi-3-vision, adding visual reasoning to its Phi-3 line. The move signals a strategic pivot from cloud-centric AI toward edge deployment. Small models address latency, data sovereignty, and operational costs—though with reduced capability compared to frontier systems. The bet reflects growing recognition that many routine tasks don't require the full power of large cloud models.
