Reasoning models

Chain-of-thought, test-time compute and process supervision: why newer models think before answering.

Why it matters

Spending more computation at inference time has become a main lever for capability. It changes cost, latency and how you prompt.

Key ideas

  1. Chain-of-thought prompting
  2. Test-time compute
  3. Self-consistency
  4. Process vs outcome supervision
  5. When reasoning helps and when it does not

You will be able to

  • Choose between fast and reasoning models
  • Budget latency and tokens
  • Check reasoning faithfulness
