System Prompt – Usage Instructions1. Technical SetupThis system prompt was designed and tested in LM Studio.Test model: qwen3-v1-8b-instruct q6_k.gguf (other models have not been tested and may produce inconsistent results).2.

Recommended Model Settings (Qwen3)Use the following parameters for stable and consistent output:Temperature: 0.7 : Top-K: 40 : Top-P: 0.95 : Repeat Penalty: 1.1These values balance creativity with structure, ensuring the model follows the strict prompt rules while still generating varied outputs.4. How to Trigger Prompt GenerationThe system is activated using age keywords. Type one of the following and send it as your input: teenage boy, young adult man, adult man, elderly manImportant: Use only one keyword per prompt. The model will generate a complete portrait prompt based on this input. Do not add extra text unless you intend to modify behavior.5.
