v4.2.8rc2 brings Prompt Templates to Invoke, plus a number of minor fixes and enhancements.

This second RC fixes an issue where the default prompt templates were not packaged correctly, causing an error on startup.

Prompt Templates

We've added the ability to create, import and export prompt templates. These are saved prompts that you may add to your existing prompt.

How it Works

Add a positive and/or negative prompt to your template. Use the {prompt} placeholder in the template to indicate where your prompt should be inserted into the template:

• Template: highly detailed photo of {prompt}, award-winning, nikon dslr
• Prompt: a super cute fennec fox cub
• Result: highly detailed photo of a super cute fennec fox cub, award-winning, nikon dslr

If you omit the placeholder, the template will be appended to the end of your prompt:

• Template: turtles
• Prompt: i like
• Result: i like turtles

Creating a Prompt Template

You can create a prompt templates from within Invoke in two ways:

• Directly, by providing the name, positive prompt and negative prompt. You can upload an image to be the preview image for the template.
• Via metadata from an image generated with Invoke. We'll use the positive and negative prompts from the image's metadata, and that image will be the preview image for that template.

Default Prompt Templates

We're shipping a number of templates with the app. We'll update these as we continue developing Invoke with improvements and new templates.

Import and Export

You can import templates from other SD apps. We support CSV and JSON files with these columns/keys:

• name
• prompt or positive_prompt
• negative_prompt

Export your prompt templates to share with others. When you export prompt templates, only your own templates are exported.

Preview and Flatten

Use the Preview button to see the prompt that will be used for generation. Flatten the prompt template to bake it into your prompts.

Thanks to @maryhipp for implementing Prompt Templates!
