§ 04 / TOKENIZER

Paste text. See tokens. See cost.

Estimate · deepseek-tokenizer-estimate · ≈4.2 chars/token Auto-counts as you type

This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.
