Earlier this year, Microsoft Research published the BitNet b1. 58 paper, demonstrating that 1-bit ternary models {-1, 0, +1} replace floating-point matrix multiplications with simple integer additions on CPU. Batch stride memory overwrites caused recurring segfaults on Apple Silicon (ARM64). PR #642: Fixes ARM64 2B batch stride memory overwrites, FFN activation alignment (SiLU vs ReLU²), and tokenizer inference bugs.
