Model Best Open-Sources BitCPM-CANN: 1.58-bit Training Achievable on Domestic Compute

Model Best open-sourced BitCPM-CANN, an end-to-end training pipeline for 1.58-bit models on domestic Chinese accelerators.

The release includes code, checkpoints, and benchmarks, and reportedly works on hardware such as Huawei Ascend via CANN.

If validated, the approach could reduce memory and compute pressure for AI training amid limited access to NVIDIA GPUs and rising HBM costs.
