+Python implementation of [GCF (Graph Compact Format)](https://gcformat.com/) — the most token-efficient wire format for LLMs. A drop-in alternative to JSON and TOON for any structured data.
 
-**84% fewer tokens than JSON. 32% fewer than TOON. 100% LLM comprehension accuracy at 500 symbols, where JSON fails.**
+**79% fewer input tokens than JSON. 75% fewer output tokens. 52% smaller than TOON. 100% LLM comprehension at 500 symbols, where JSON fails at 66.7%.**
