The 4 Properties of AI
This tutorial explains the four core properties of AI: next token prediction, knowledge, working memory, and steerability. Each property has its capabilities and limitations, with Claude-specific features to mitigate them.

Working Memory
What is AI paying attention to?
Steerability
How much am I in control?
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.
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.
Watch the lesson · 6 min
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
