PrismML released Bonsai 27B, a compressed version of Alibaba's Qwen model shrunk from 54GB to 3.9GB using 1-bit and ternary quantization. The 1-bit build is designed to fit within iPhone 17 Pro's memory budget, running a 27B-parameter model on-device. The compression achieves 10-15x memory reduction, 6-8x speed improvement, and 3-6x energy savings, at a cost of roughly 5-10% performance degradation. Apple's interest is driven by its Siri overhaul in iOS 27, privacy goals, reduced cloud costs, and hardware memory constraints. Analysts note that real-world performance across millions of devices remains unproven, and that edge AI shifts compute from data centers to phones rather than eliminating it. ## Full article daily.dev links to this article rather than hosting it.
