## Description:
|
||||
TL;DR: Lets the bot answer you with a picture!
|
||||
|
||||
Stable Diffusion API pictures for TextGen, v.1.1.0
|
||||
An extension to [oobabooga's textgen-webui](https://github.com/oobabooga/text-generation-webui) allowing you to receive pics generated by [Automatic1111's SD-WebUI API](https://github.com/AUTOMATIC1111/stable-diffusion-webui)

|
||||
|
||||
Load it in the `--chat` mode with `--extension sd_api_pictures` alongside `send_pictures` (it's not really required, but completes the picture, *pun intended*).
|
||||
|
||||
The image generation is triggered either:
|
||||
- manually through the 'Force the picture response' button while in `Manual` or `Immersive/Interactive` modes OR
|
||||
- automatically in `Immersive/Interactive` mode if the words `'send|main|message|me'` are followed by `'image|pic|picture|photo|snap|snapshot|selfie|meme'` in the user's prompt
|
||||
- always on in Picturebook/Adventure mode (if not currently suppressed by 'Suppress the picture response')
|
||||
|
||||
## Prerequisites
|
||||
|
||||
One needs an available instance of Automatic1111's webui running with an `--api` flag. Ain't tested with a notebook / cloud hosted one but should be possible.
|
||||
To run it locally in parallel on the same machine, specify custom `--listen-port` for either Auto1111's or ooba's webUIs.
|
||||
|
||||
## Features:
|
||||
- API detection (press enter in the API box)
|
||||
- VRAM management (model shuffling)
|
||||
- Three different operation modes (manual, interactive, always-on)
|
||||
- persistent settings via settings.json
|
||||
|
||||
The model input is modified only in the interactive mode; other two are unaffected. The output pic description is presented differently for Picture-book / Adventure mode.
|
||||
|
||||
Connection check (insert the Auto1111's address and press Enter):
|
||||
|
||||
|
||||
### Persistents settings
|
||||
|
||||
Create or modify the `settings.json` in the `text-generation-webui` root directory to override the defaults
|
||||
present in script.py, ex:
|
||||
|
||||
```json
|
||||
{
|
||||
"sd_api_pictures-manage_VRAM": 1,
|
||||
"sd_api_pictures-save_img": 1,
|
||||
"sd_api_pictures-prompt_prefix": "(Masterpiece:1.1), detailed, intricate, colorful, (solo:1.1)",
|
||||
"sd_api_pictures-sampler_name": "DPM++ 2M Karras"
|
||||
}
|
||||
```
|
||||
|
||||
will automatically set the `Manage VRAM` & `Keep original images` checkboxes and change the texts in `Prompt Prefix` and `Sampler name` on load.
|
||||
|
||||
---
|
||||
|
||||
## Demonstrations:
|
||||
|
||||
Those are examples of the version 1.0.0, but the core functionality is still the same
