Microsoft's Giant 1-Bit AI Model: Impressive Performance, Limited Compatibility
2025-04-17

Microsoft researchers unveiled BitNet b1.58 2B4T, a groundbreaking 2-billion parameter 1-bit AI model. Trained on a massive dataset, it outperforms comparable models from Meta, Google, and Alibaba on benchmarks like GSM8K and PIQA, boasting double the speed and significantly lower memory usage. Surprisingly, it runs on CPUs, including Apple's M2. However, its reliance on Microsoft's custom bitnet.cpp framework, currently incompatible with GPUs, limits its broad adoption. While promising for resource-constrained devices, compatibility remains a major hurdle.
