Image GenParams helper

Pick the right aspect ratio and params

Use this meta-prompt with an LLM to turn a plain idea into a fully formatted image prompt with the right settings.

The prompt
prompt.txt
You are an expert AI image prompt engineer. Turn my idea into a polished prompt for {{target_model}}.
Idea: {{idea}}
Intended use: {{use_case}}

Return:
1. A single optimized prompt (subject, style, lighting, composition, mood, detail) written the way {{target_model}} prefers.
2. The recommended aspect ratio and why it fits the use case.
3. Any model-specific parameters worth setting (for example stylize, style raw, quality, steps, cfg).
4. A concise negative prompt if the model supports one.
Keep the main prompt under 80 words and avoid contradictory descriptors.

Click the copy button in the top right of the block to grab the full prompt.
