A developer has created a new Triton backend for the Falcon3-10B-1.58bit model, significantly boosting inference speed on an NVIDIA RTX 5070 GPU. The new backend achieved 97.5 tokens per second for decoding, a nearly 10x improvement over the stock Transformers BitLinear implementation. This optimization utilizes techniques like K-contiguous packed ternary weights, a packed-word DP4A decode path, and CUDA Graph replay, with the developer seeking further reproductions and benchmarks on different GPU architectures.
