Advanced Concepts
Chain of thought
CoT
Intermediate reasoning steps used by a model while working toward an answer.
Example
A model works through intermediate reasoning before presenting its final answer.
Why it matters
Working through intermediate steps can help a model handle problems with connected parts.
You'll hear it
“The steps look sensible, but does the final number check out?”
Can you control it?
Not directly
No, not directly. Chain of thought describes a learned property, observed result, or broader concept rather than a normal user setting. You may influence it indirectly by changing the tool, data, prompt, or workflow.
Common questions
- Can I always see the model's internal reasoning?
- No. Some services show only an answer or a summary rather than the full internal process.
- Is a written explanation a faithful record of how it answered?
- Not necessarily. The explanation may be generated separately and should not be treated as a complete internal record.
- Does asking for more steps always help?
- No. It can add unnecessary text or elaborate on a mistake, especially on simple tasks.
