Citi Research introduces edge AI architectures, ushering in the era of personal AI servers. These on-device AI systems promise ultra-low latency, enhanced privacy, bandwidth savings, and offline capabilities. Model compression and innovative packaging make edge deployments feasible and performant, revolutionizing AI operations across smartphones, PCs, and consumer devices.

Three pillars of edge AI architectures include PCIe-connected AI modules for modular upgrades, near-processor LPDDR6 integration for bandwidth doubling and power efficiency, and integrated LPW/LLW DRAM next to AI cores for peak performance and minimal latency. These advancements aim to minimize bottlenecks and enable real-time processing of vision, speech, and natural language tasks on handheld devices.

DeepSeek’s model compression techniques like knowledge distillation, reinforcement learning, and Mixture-of-Experts enable efficient models for edge AI. These innovations shrink model size while maintaining accuracy, allowing modern transformer architectures to operate on the edge for functions like on-device summarization, personalized recommendations, and zero-shot translation.

The roadmap for edge AI adoption spans from proof-of-concept in flagship devices with LPDDR6-adjacent NPUs and selective SoIC rollouts to mainstream adoption with LPDDR6+NPU combos in mid-range devices and widespread SoIC packaging in tablets and laptops. By 2028, the ecosystem is expected to expand with developers transitioning to hybrid toolchains for new on-device use cases, bringing the personal AI server closer to reality.
