The design uses the EEPROM in an odd way. Each CPU address really addresses ... is for a true flag register. The I/O is a bit peculiar. Each phase 1 instruction selects an input to store in ...

To wit we present this lovely single-board computer sporting a 1-bit CPU ... it offers a great degree of design flexibility. [Simon] chose a 4-bit address space, but with a little wizardry ...

Memory requirements are the most obvious advantage of reducing the complexity of a model's internal weights. The BitNet b1.58 ...

The repository describes bitnet.cpp as offering “a suite of optimized kernels that support fast and lossless inference of 1.58-bit models on CPU (with NPU and GPU support coming next).

Microsoft’s model BitNet b1.58 2B4T is available on Hugging Face but doesn’t run on GPU and requires a proprietary framework.

Microsoft researchers claim they’ve developed the largest-scale 1-bit AI model ... lowers the number of bits — the smallest units a computer can process — needed to represent those weights ...
