The 77% figure is company-measured on one workload, so broader deployment evidence will determine how far it travels.\n\n[Dharma-AI](https://dharma-ai.com.br/en/dharma-ai-2/?ref=runtimewire) says its VocabX method cut measured inference cost by 77% on a production Portuguese essay grader. The result suggests tokenizer design can be part of cost reduction for specialized AI.
