Tencent Hunyuan released an official 1-bit quantization for the Hy4 model. Results shared on X show minimal accuracy drop compared to BF16: MCP Atlas (83.7→83.2), SWE-Bench multi (82.9→81.3), MRCR (81.3→81.1), and IFBench (73.5→72.5). The poster notes they haven't tried it yet due to insufficient RAM but finds the results promising.
