Rough token estimates
- GPT-4o / GPT-5 class0~4 Latin chars / token, ~1.5 CJK
- Claude class0~3.8 Latin chars / token
- Gemini class0~4.2 Latin chars / token
- Word-ish floor0words×1.3 + CJK×0.9
These are drafting heuristics (chars ÷ family average), not tiktoken / official tokenizers. Use the API cost calculator for dollar estimates.
