Nextcloud AI Image generator bot

Uses SDXL-Turbo for fast image generation.

Using the RTX 3060 12GB, bot is capable of processing 2 requests per second.

Warning

Note: Model loaded in GPU memory uses ~9.4GB. Can be run on CPU but will require ~2x of memory.

Models remain in memory after a request, for faster processing of subsequent requests.

Memory is freed after an hour of inactivity.

How to use

1. Install ExApp from AppStore
2. Wait for models download and initialization(6.5 Gb for GPU, 13 Gb for CPU)
3. Enable talk bot in your room
4. Use @image mention to send prompts: @image cinematic portrait of fluffy cat with black eyes
5. Image will be posted to room and stored into image_generator_bot folder at the user's root.

State of support

The project is being developed in personal and free time, any ideas or pull requests are welcome.

Note: We understand that the model used here is quite old and cannot compare with the new SDXL-Lightning

We are currently working on a new much more advanced image generation project which you can find here: Visionatrix

If this is of interest to the Nextcloud community, we can try to adapt Visionatrix either as an Image Provider for Nextcloud 30 or simply as an AppAPI Nextcloud application.
