TokTier: Exact Stateful Tokenization for Agentic LLM Serving

En 30 secondes

Ce qui s'est passé

TokTier is a stateful tokenization service that reuses token boundaries across agent LLM calls, avoiding full re-tokenization of long transcripts with small appends.

Pourquoi ça compte

Matters for engineers building agentic systems where coding agents resubmit long context after each tool result, causing tokenization to consume up to 64% of time to first token.

Vigilance

System requires per-request stable-boundary checks and falls back to full tokenization on failure; exact correctness verified against reference tokenizers across 17 families.
