Tokenization

Tokenization is the process of breaking text into smaller units (tokens) that an AI model can process. Modern large language models use subword tokenizers like Byte-Pair Encoding (BPE), WordPiece, and SentencePiece — these split text into pieces that may be whole words, parts of words, or even single characters depending on frequency. For example, "governance" might be one token, but "AI-driven" might split into three. Tokenization choices affect model behavior, cost (since pricing is per-token), accuracy across languages (some tokenizers handle non-English text inefficiently), and context window utilization. OpenAI's tiktoken library, Hugging Face's tokenizers library, and Google's SentencePiece are common implementations. The same string can produce very different token counts under different tokenizers — sometimes 30% more or less. AI governance frameworks require documenting tokenization to support AI compliance, AI risk management, and equitable performance under responsible AI principles, especially for multilingual deployments.

Centralpoint Meters Every Token, Across Every Model: Oxcyon's Centralpoint AI Governance Platform tracks tokenization-driven costs no matter which model you run — ChatGPT, Gemini, Llama, or embedded. The platform is model-agnostic, keeps prompts and skills strictly on-premise, and embeds multiple chatbots into any digital experience with one JavaScript line.
