  - `Interrogate: maximum descripton length` - maximum length for BLIP model's text
  - `Interrogate: maximum number of lines in text file` - interrogator will only consider this many first lines in a file. Set to 0, default is 1500, which is about as much as a 4GB videocard can handle.

+Prompt editing allows you to start sampling one picture, but in the middle swap to something else. The base syntax for this is:
+
+```
+[from:to:when]
+```
+
+Where `from` and `to` are arbitrary texts, and `when` is a number the defines how late in the sampling cycle should the switch be made. The later it is, the less power the model has to draw the `to` text in place of `from` text. If `when` is a number between 0 and 1, it's a fraction of the number of steps after which to make the switch. If it's integer greater than zero, it's just the step after which to make the switch.
+
+Additionally:
+- `[to:when]` - adds `to` toprompt after a fixed number of steps (`when`)
+- `[from::when]` - removes `from` from prompt after a fixed number of steps (`when`)
+
+For example, here's how a prompt `fantasy landscape with a [mountain:lake:0.25] and [an oak:a christmas tree:0.75][ in foreground::0.6][ in background:0.25] [shoddy:masterful:0.5]` will look to sampler with 100 steps:
+
+at start, `fantasy landscape with a mountain and an oak in foreground shoddy`
+after step 25, `fantasy landscape with a lake and an oak in foreground in background shoddy`
+after step 50, `fantasy landscape with a lake and an oak in foreground in background masterful`
+after step 60, `fantasy landscape with a lake and an oak in background masterful`
+after step 75, `fantasy landscape with a lake and a christmas tree in background masterful`
+
+The picture at the op was made with prompt:
+
+`Official portrait of a smiling world war ii general, [male:female:0.99], cheerful, happy, detailed face, 20th century, highly detailed, cinematic lighting, digital art painting by greg rutkowski`
+
+And the number 0.99 was replaced with whatever you see in column labels on the image.
