A developer has created a C inference engine designed for BitNet models, focusing on zero dependencies and CPU performance. The engine achieves 36.25 tokens per second on a BitNet b1.58-2B-4T model running on an Intel Xeon CPU. Key optimizations include native ternary SIMD using AVX2/AVX-512 instructions and efficient thread synchronization. The developer noted that inference speed at batch size one is primarily limited by memory bandwidth, suggesting that batching multiple sequences is necessary for faster compute kernels to improve end-to-end latency.
