Standard example has 2 commas

[rowild]

I am new to comfyUI. Having it set up on a Mac M2, I immediately see that there is already a prompt given. But that prompt has 2 commas:

beautiful scenery nature glass bottle landscape, , purple galaxy bottle,

Do the extra comma and extra space have a special meaning?

It plays a role in clearly separating both sides when encoding by spreading the distance between tokens.

Thank you very much for your quick reply! However, I do understand the words of your reply, but not the meaning. What are the "both sides" in this case?
(I am new to this stuff; with your info I searched Google for "distance between tokens" and got some insight into that; but here the "two side" do not yet make sense to me – any help would be most welcome!)

"beautiful scenery nature glass bottle landscape" and "purple galaxy bottle".
It mitigates the impact of each part's prompt on another prompt. Of course, it's not a perfect solution; it's just one technique.

Adding a comma implies inserting additional tokens, and having more tokens positioned between the front and back parts weakens the correlation.
