A new weight representation called TKintegers K5 has been developed, which uses five balanced ternary digits to represent each weight code. This implementation achieved significantly higher throughput on an NVIDIA L4 GPU compared to a standard TorchAO FP8 baseline, despite the GPU lacking native K5 instructions. Specifically, K5 demonstrated 3.21x prefill and 3.10x decode throughput on the Qwen2.5-0.5B-Instruct model, highlighting the potential of novel weight representations to improve inference efficiency on existing hardware.
