JSON wastes tokens on syntax. TOON removes that noise and gives you lower cost, better outputs, and more usable context. JSON stays for APIs — TOON lives inside AI systems. TOON (Token-Oriented Object Notation) is a lightweight, instruction-style data format designed specifically for token-based AI systems. Instead of heavy syntax ({}, :, ,, " "), TOON focuses on: Less noise. Same meaning. Better for AI. Because LLMs don’t care about punctuation — they care about tokens. Format: JSON Average Tokens: 45–55 Format: TOON Average Tokens: 28–32 That’s a 35–45% reduction in tokens for the same data. JSON: ~36 million tokens per month TOON: ~22 million tokens per month ~14 million tokens saved every month ~40% reduction in AI API cost Cleaner samples mean better embeddings and cheaper fine-tuning. Fewer tokens, less noise, better learning signals. LLMs follow instruction-style formats more reliably than strict JSON. JSON often breaks due to missing commas or braces. TOON degrades gracefully and remains usable even when partial. score 82 feedback Clean architecture and reusable components TOON is not a replacement for JSON everywhere. Best practice architecture: User → TOON → LLM → TOON → Parser → JSON (for APIs / storage) This gives you cost efficiency without losing compatibility. At scale, token efficiency directly translates into profitability and growth. Read line Split by space First token → key Remaining tokens → value Indentation → hierarchy No heavy parsers. No strict failures. Easy recovery. Use TOON if you are building: JSON was built for humans. TOON is built for AI. If AI thinks in tokens, our internal data formats should too. Would you try TOON in your AI system? Should AI-native data formats exist officially? Want an open-source TOON parser?
