A glossary covering tokens, transformers, inference, and fine-tuning, the core vocabulary of LLMs.

Contrasts deterministic code logic with Claude's probabilistic, pattern-based approach to generating answers.

Clarifies why Claude reasons and drafts responses instead of retrieving pre-written, indexed answers.

Enumerates practical habits for evaluating, piloting, and responsibly rolling out Claude across a team.
