In machine learning, the cold boot is a process when starting your model after a pause. Currently, your model is kept 'warm' for 5 minutes.
If you are not generating new photos using your model for more than 5 minutes, it will be 'turned off.' The next time you try to generate a new image, you must wait until your model is 'warm' again.
Unfortunately, keeping your model in ready-to-use mode for longer than 5 minutes is not possible.
The main reason is the cost of the GPU servers. Running multiple servers with all models 24/7 would be too expensive.
