Reasoning Models

Inside the 'Chain of Thought' of System 2 AI.

System 1 vs System 2 Thinking

Learn the difference between "Fast Chat" and "Deep Reasoning" (like o1).

Standard Model

  • ✅ Fast Latency
  • ✅ Lower Cost
  • ❌ Prone to Logic Errors
Selected

Reasoning Model (o1)

  • ✅ Deep Intelligence
  • ✅ Self-Correction
  • ❌ Higher Latency & Cost
The Logic Test
"If I have 3 oranges and you give me 2 apples, then I eat 1 orange and give you 1 apple, how many fruits do I have left?"

What is Inference-Time Compute?

Reasoning models like OpenAI o1 use "Chain of Thought" internally. They are trained to evaluate multiple paths and correct their own mistakes before producing a final answer. This is different from standard models that predict the very next token immediately.

The "System 2" Opportunity

Don't use Reasoning models for everything. They are 10-100x more expensive and have high latency. Use them for strategy, complex coding, and RAG verification—but stick to standard models for simple chat and summary.
