According to DeepLearning.AI, Microsoft and its academic collaborators have released an updated version of BitNet b1.58, where all linear-layer weights are constrained to -1, 0, or +1, effectively reducing each weight's storage to approximately 1.58 bits. Despite this extreme quantization, BitNet b1.58 achieved an average accuracy of 54.2 percent across 16 benchmarks spanning language, mathematics, and coding tasks. This development highlights a significant trend toward ultra-efficient AI models, which can lower computational and energy costs while maintaining competitive performance, offering strong potential for deployment in edge computing and resource-constrained environments (Source: DeepLearning.AI, July 4, 2025).
