GigaToken: A SIMD-based tokenizer library claiming 1000x speedup over HuggingFace

Short summary

GigaToken is a Rust-based tokenizer library claiming up to 1000x speedup over HuggingFace tokenizers, reaching 24.53 GB/s on server CPUs. It uses SIMD-based pretokenization instead of regex to bypass the bottleneck limiting existing tools like Tiktoken to ~36 MB/s. The library offers a compatibility mode matching HuggingFace outputs byte-for-byte and a native mode for maximum throughput across 20+ tokenizer families.

• •GigaToken achieves 24.53 GB/s tokenization vs ~25-50 MB/s for HuggingFace tokenizers
• •SIMD pretokenization replaces regex-first architecture for massive speedup
• •Drop-in HF compatibility mode plus native API; consistent across EPYC, M4 Max, and Ryzen CPUs
