LLM Token Cost Optimizer
Jacob Ralph
Phrase-based codebook system that cuts LLM token usage and cost.
Problem: token pricing adds up fast, and AI outputs repeat the same phrases, wasting cost, bandwidth and storage.
What we built: a codebook that replaces frequent multi-token phrases in JSON responses with short codes, while keeping full responses easy to reconstruct.
Stack: Node.js, OpenAI
