Next Token Prediction

Where do AI answers come from?

Generative AI writes answers word by word based on what tends to follow what. It is a vastly sophisticated autocomplete — not a search engine.

What this enables

  • Fluent, natural-sounding text in any style
  • Rapid synthesis across large amounts of material
  • Strong performance on tasks resembling its training data

Where it characteristically fails

  • Hallucination — plausible isn't the same as true
  • Confabulation concentrates in specifics: names, dates, citations, stats, URLs
  • Misplaced confidence — smooth prose wraps a guess

Claude features that push the edge out

Citations & source grounding Constrained generation Generator–verifier loops

Knowledge

What does AI actually know?

What the model knows comes entirely from its training data, frozen at a knowledge cutoff — what it read, and when it stopped reading.

What this enables

  • Extraordinarily broad general knowledge
  • Deep competence in well-represented domains
  • Unexpected connections across fields

Where it characteristically fails

  • Knowledge cutoff & staleness — true-then isn't true-now
  • Uneven coverage of niche, local, or recent topics
  • Source amnesia — "I read this somewhere" isn't a citation

Claude features that push the edge out

Web search Retrieval (RAG / connectors) Tool use for real-time data

Working memory

What is the AI paying attention to right now?

Everything the model is attending to lives inside a fixed-size context window. Context is leverage — until you hit the cliff.

What this enables

  • Rapid in-session adaptation to your docs, data, and constraints
  • Coherent work across long threads while space remains
  • Precise grounding in supplied material

Where it characteristically fails

  • Hard length limits — a cliff, not a gradient
  • "Lost in the middle" — buried details get less attention
  • No persistent memory by default; corrections don't carry over

Steerability

How much am I in control?

The model follows instructions by continuing a pattern, not by understanding intent. Remarkably steerable — but a gap always exists between what you meant and what landed.

What this enables

  • Precise control over format, style, length, and tone
  • Role-setting and persona
  • Multi-step execution and iterative refinement

Where it characteristically fails

  • Reasoning drift — small errors compound over long chains
  • Letter-over-spirit — instruction honored, intent missed
  • Prompt injection — other text in context can steer it too

System prompts / custom instructions Extended (visible) thinking Code execution
