<h3>How to use LORAs:</h3>
|
|
<p>Include LORAs in your prompt using this syntax: <code>[lora-name:weight]</code></p>
|
|
<p>Example: <code>a beautiful landscape by [my-artist-lora:0.8]</code></p>
|
|
<p>Weight values typically range from 0.1 to 1.0</p>
|
|
<p><strong>Note:</strong> Angle brackets (< >) are not allowed in prompts. Use square brackets instead.</p>
