⚙️ 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.
