Unverified50% confidenceSolutionExact time
Mixed-precision quantization applies aggressive low precision such as INT4 to backbone networks that have large parameter counts but are not precision-sensitive, while retaining INT8 or FP16 for precision-sensitive components such as text encoders and QKV projections.
