Definition

Tokenization is the way an AI language model splits text into smaller units it can process.

01

Why Tokenization matters at work

Models process tokens rather than words directly. Tokenization affects context usage, cost, latency, and how text in different languages or formats is represented; token counts are model-specific.

02

A practical workplace example

Example

A team checks token counts for multilingual support documents before setting chunk sizes and budgets for its retrieval pipeline.

03

What teams should evaluate

  1. 01

    Compare quality, latency, context limits, reliability, and total operating cost on the same representative evaluation set.

  2. 02

    Record the model, tokenizer, configuration, and version used so a result can be reproduced and changes can be investigated.

  3. 03

    Review data rights, privacy requirements, security boundaries, and provider retention policies before sending workplace information.
