Tencent’s HunYuan team said it compressed Hy4 preview model weights from 1.5TB to about 214GB. The team reports the compressed model retains near-original long-document comprehension, matches the full model on multi-turn long-context retrieval, and shows only a slight decline in math ability; overall performance is described as within acceptable ranges. The model covers coding assistance, tool calling, long-document processing and routine Q&A.
