OpenBMB releases BitCPM-CANN at 1.58 bits on Huawei Ascend hardware

OpenBMB has released BitCPM-CANN, a 1.58-bit quantized model, with early testing underway on Huawei's Ascend 910B accelerators. The ultra-low bitwidth approach challenges conventional model compression trade-offs.

OpenBMB released BitCPM-CANN, a model quantized to 1.58 bits, and the team is conducting early testing on Huawei's Ascend 910B accelerators. The ultra-low bitwidth represents an aggressive push toward extreme model compression—well below the 4-bit and 8-bit quantization schemes that have dominated p...
