Text · Tokens

Purpose: count exact tokens (o200k/cl100k) and check a token budget. Exact token counts for prompts and documents in one deterministic call (no LLM, no network): OpenAI BPE encodings o200k_base (GPT-4o / GPT-4.1 / o-series) and cl100k_base (GPT-4 / GPT-3.5 / text-embedding-3), plus chars, words, bytes and approxTokens: a script-aware estimate (CJK / code / other text, separate ratios; method, per-segment breakdown and error range in approx). budget is always checked against the exact BPE count, never the estimate. Send {text} or up to 100 {texts} (per-item and total counts). Optional maxTokens
