How Parameters Interact
No parameter operates in isolation. They form a system:
- Temperature + Top-P together control the creative diversity of output. Use one OR the other as the primary creative lever (many practitioners recommend setting Top-P = 1 when tuning Temperature, and Temperature = 1 when tuning Top-P).
- Top-K acts as a hard ceiling on diversity, regardless of Temperature or Top-P.
- Frequency + Presence Penalties operate independently on the generated output after the temperature/sampling step.
- Max Response is a hard limit that overrides everything — if the model hits the token cap, it stops, even mid-sentence.
The Complete Parameter Reference Dashboard
| Parameter | Range | Default | Low Value Behavior | High Value Behavior |
| Temperature | 0–2 | 0.7 | Deterministic, repetitive, precise | Random, diverse, creative |
| Top-K | 1–∞ | Varies | Very focused — 1 = always same word | Wide variety from large candidate pool |
| Top-P | 0–1 | 0.95 | Tight nucleus — only top tokens | Large nucleus — more vocabulary diversity |
| Freq. Penalty | 0–2 | 0 | Free repetition | Actively avoids repeating words |
| Pres. Penalty | 0–2 | 0 | Stays on topic | Explores new topics and vocabulary |
| Max Response | 1–∞ tokens | Varies | Short, sometimes cut off | Full responses, higher cost |

Platform-Specific Parameter Access
| Platform | How to Access Parameters | Notes |
| OpenAI (ChatGPT API) | Temperature: 0.0 – 2.0 API call: temperature, top_p, frequency_penalty, presence_penalty, max_tokens | Full parameter control via Playground UI or code |
| Microsoft Copilot | Temperature: Not configurable from consumer UI | Parameters set internally; use via API for control |
| Google Vertex AI Studio | UI sliders: Temperature 0–2, Top-K, Top-P | Most parameters accessible via UI |
| Meta LLaMA (API) | Usually Temperature: 0.0 – 2.0 (implementation dependent | Accessed via API or local model config file |
| ChatHCP / Enterprise | Temperature fixed at 0 in some deployments | Check your enterprise configuration |
| Anthropic Claude (API) | Temperature: 0.0 – 1.0 | No Frequency/Presence penalty; use model-level guidance |
