+| GGUF F32 / F16 and block quantization | Supported. CPU keeps the supported Q, IQ, and MXFP4 blocks compressed through the matrix multiply. CUDA also keeps the supported Q8_K-activation formats compressed; other formats fall back to expansion or CPU compute. Set `VT_GGUF_KEEP_QUANT=0` to disable the direct path. See [STATUS.md](STATUS.md) for the exact format and backend coverage |
