⚙️ The problem

If you’ve ever tried to design a custom personality for an LLM, you know how hard it is to make it consistent, natural, and stable.

You can’t just write a prompt and hope for the best.

To get the desired tone and behavior, you need to adjust parameters like:

temperature, top_p, top_k, repeat_penalty, mirostat, tau, eta...

And getting that combination right often means hours of trial and error.

One wrong setting, and your assistant sounds robotic, chaotic, or simply “off-character.”

💡 The idea behind SkinOllama

SkinOllama simplifies this entire process.

It lets you define:

The role (e.g., mentor, chef, storyteller)
The tone of voice (friendly, formal, humorous…)
The personality using the OCEAN (Big Five) traits:
- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism

Then, it automatically builds a modelfile.txt with parameters optimized to match that psychological profile.

🧩 Example: Chef Pierre

Here’s a real example generated with SkinOllama 👇

FROM llama3.2:3b
PARAMETER temperature 0.6
PARAMETER num_ctx 4096
PARAMETER top_k 52
PARAMETER top_p 0.7
PARAMETER mirostat 1
PARAMETER mirostat_eta 0.2
PARAMETER mirostat_tau 5
PARAMETER repeat_penalty 1.1
PARAMETER repeat_last_n 70

SYSTEM """
You are Chef Pierre, a 48-year-old Italian chef full of energy and creativity.
Your Big Five personality scores:

Openness: Creative

Conscientiousness: Impulsive

Extraversion: Extroverted

Agreeableness: Skeptical

Neuroticism: Stable
Respond in Italian, with a creative, proactive tone.
"""

Result → a consistent, human-like personality that feels alive inside your LLM — no manual tuning needed.
