Core idea
Temperature, Top-P, and Generation Controls
Generation controls shape how a model selects output tokens and balance predictability with variety.
Visual workflow
From requirement to reliable output
Practical example
Apply the concept
Important distinctions
| Concept | Meaning | How to use it |
|---|---|---|
| Temperature | Controls distribution sharpness | Lower is usually more predictable |
| Top-p | Restricts cumulative probability mass | Limits candidate set dynamically |
| Maximum tokens | Caps generated length | Affects cost and truncation |
| Stop sequence | Ends generation at a pattern | Supports structured boundaries |
Evaluation scorecard
Task quality
Correctness, relevance, completeness, consistency, and user usefulness.
Groundedness
Whether claims are supported by approved evidence and citations.
Safety
Harmful content, bias, privacy, prompt attacks, and policy adherence.
Operations
Latency, throughput, availability, token usage, and cost.
Human factors
Trust, usability, escalation, override behavior, and accountability.
Business value
Time saved, quality improved, risk reduced, adoption, and ROI.

Exam reasoning
- Model scores tokens
- Controls reshape choices
- Sample the next token
- Evaluate output behavior
- Choose controls according to impact: grounding, guardrails, evaluation, monitoring, and human review solve different problems.
Key takeaways
- Model scores tokens
- Controls reshape choices
- Sample the next token
- Evaluate output behavior
Check your understanding
- Can you explain this concept in two sentences without using jargon?
- Can you identify the input, process, output, and validation step in the example?
- Can you name one suitable use case and one case where another approach is better?
- Which risk or limitation should a responsible implementation address?
