By understanding how AI agent memory parameters work, you can, in turn, dramatically improve the quality of your prompts and, consequently, achieve better results. Whether you’re aiming for creative variation or technical accuracy, adjusting settings like Temperature, Top P, and Frequency Penalty makes all the difference. In this guide, we’ll break down each parameter, clearly explain its role, and then provide recommended values for different use cases—ranging from imaginative image prompts to highly consistent text generation.

What Are AI Agent Memory Parameters
AI agent memory parameters are adjustable settings that, in turn, influence how AI models—such as ChatGPT or MidJourney—not only interpret prompts but also generate outputs. As a result, these parameters help control the style, accuracy, and creativity of the responses.
In other words, they determine how creative, consistent, or focused your prompts will be.
By adjusting these values strategically, you can fine-tune results for your specific needs — whether you’re aiming for artistic variety or technical precision.
Temperature Settings in AI Agent Memory Parameters 🌡️
What it does
Controls the randomness and creativity of the AI’s output. In other words, it determines how unpredictable or structured the response will be.
Creative Setting
Temperature 0.8 – 1.2
As a result, outputs are imaginative, diverse, and less predictable.
This is particularly ideal for artistic prompts and creative writing, especially when variation and originality are key.
Example
For instance, you’ll get a unique Pixar-style description each time.
Accurate Setting
Temperature 0.1 – 0.4
Conversely, this ensures consistent and logical responses.
It’s perfect for technical prompts or format-based tasks where precision is key.
Example
For example, the output stays consistent across multiple runs.
Pro Tip
If the output feels too chaotic, lower the temperature slightly.
Top P (Nucleus Sampling) in AI Agent Memory Parameters 🎯
What it does
Limits the AI’s word choices to the top-most-probable options. In other words, it narrows the vocabulary the model can select from.
Creative Setting
Top P 0.9 – 1.0
This allows more variety and a richer vocabulary. As a result, it’s best for imaginative, metaphorical responses.
Example
Uses rare adjectives or poetic phrasing.
Accurate Setting
Top P 0.1 – 0.5
This keeps outputs focused by sticking to clear, common language. Therefore, it’s great for technical instructions and structured prompts.
Example
Consistently uses standard MidJourney syntax.
Pro Tip
For more nuanced control, pair Top P with Temperature.
Frequency Penalty in AI Agent Memory Parameters 🔄
What it does
It reduces the repetition of words in the same output. As a result, it helps vary language and avoid redundancy.
Creative Setting
Frequency Penalty 0.5 – 1.0
As a result, it encourages the use of fresh, unique language.
This makes it ideal for storytelling and image-rich prompts, where variety enhances visual impact.
Example
Each prompt, therefore, uses new descriptive words.
Accurate Setting
Frequency Penalty 0.0 – 0.3
In contrast, this allows repetition of key terms when consistency is important.
It works best for prompts that must include specific formatting or technical flags.
Example
Includes –ar, –v 7 reliably, ensuring prompt structure remains intact.
Pro Tip
Use lower values when repeating technical keywords is necessary.
Presence Penalty in AI Agent Memory Parameters 📝
What it does
Discourages repeating themes or topics already mentioned. As a result, it helps vary content and shift focus.
Creative Setting
Presence Penalty 0.5 – 1.0
Consequently, the AI introduces new ideas and directions
Great for rich, multi-layered outputs
Example
Unexpected artistic elements are added to each prompt
Accurate Setting
Presence Penalty 0.0 – 0.3
Therefore, the AI stays focused on the main topic
Ideal for factual or technical content
Example
Output sticks strictly to your original prompt, without drifting
Max Tokens 📏
What it does
Sets the maximum response length in tokens (words + punctuation). In other words, it controls how long the AI’s output can be.
Creative Setting
Max Tokens 1000 – 2000
As a result, it allows longer, more detailed prompts and stories
Ideal for descriptive content and long-form responses
Example
A full Pixar-style scene with multiple elements
Accurate Setting
Max Tokens 500 – 1000
This setting keeps outputs short and efficient
Perfect for concise commands or structured outputs
Example
Only includes necessary prompt components
Pro Tip
For best results, adjust token limits based on the complexity of your output needs.
Recommended Settings by Use Case

📊 Quick Reference Table
| Parameter | Creative | Balanced | Accurate |
|---|---|---|---|
| Temperature | 0.9 – 1.2 | 0.7 – 0.8 | 0.1 – 0.4 |
| Top P | 0.9 – 1.0 | 0.8 – 0.9 | 0.1 – 0.5 |
| Frequency Penalty | 0.7 – 1.0 | 0.4 – 0.6 | 0.0 – 0.3 |
| Presence Penalty | 0.6 – 1.0 | 0.3 – 0.5 | 0.0 – 0.3 |
| Max Tokens | 1500 – 2000 | 1000 – 1500 | 500 – 1000 |
💡 Expert Tips for AI Prompt Engineers
Firstly, start with balanced settings for MidJourney
Temperature 0.7 and Top P 0.85 provide reliable creative results with structure
If the results appear too random
Lower the Temperature or the Top P slightly to regain control.
If outputs feel repetitive or too similar
Try increasing the Temperature or Frequency Penalty for more variation.
Also, ensure key flags like --ar and --v 7 are always included.
To support this, use a lower Frequency Penalty (e.g. 0.1–0.3), which allows repetition of essential terms without limiting output quality
Moreover, test the same prompt multiple times
This helps you compare creativity versus consistency across different settings
Finally, adjust incrementally
Small tweaks often lead to big improvements in output behavior
✅ Conclusion
In conclusion, tuning your AI agent’s memory parameters helps you shape outputs with precision.
Whether you’re designing creative image prompts or crafting repeatable technical formats, settings like Temperature, Top P, Frequency Penalty, and Max Tokens give you full control over AI behavior.
For your 3-prompt generator
To begin with, use balanced settings to ensure each prompt is creative, unique, and follows formatting rules consistently.
Recommended Configuration
Temperature 0.7
Top P 0.85
Frequency Penalty 0.5
Presence Penalty 0.4
Max Tokens 1200
This setup strikes the right balance. On one hand, it encourages artistic variety; on the other, it still maintains structure and, importantly, ensures essential parameters are reliably included.
This ensures each of your prompts (Pixar-style, Artistic, Best Representation) is optimized for both creativity and consistency.
