The four properties of AI

This tutorial offers a full overview of the four properties of AI. It's a quick reference to help you understand the things that make AI capable in some situations and limited in others.

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.

Watch the lesson · 5 min

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

Claude features that push the edge out

Memory Projects Context compaction File & artifact attachments

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.

Watch the lesson · 5 min

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

Claude features that push the edge out

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