### What are (parentheses) and \[brackets] in Stable Diffusion?

* () is more emphasis
* \[] is less emphasis, {} is NAI’s “implementation” of (),
* <> is for embeddings, decimals specify the number of ()’s so you don’t need to type in a bunch.

**(Blue hair) would have more weight than \[Blue hair] in the final result, (blue hair:1.4) would increase the blue hair by \~40% more than what it would’ve normally been, (blue hair:0.6) will decrease it by \~40%.**

**If using multiple (parenthesis) instead of decimals, is changed by a multiplier of 1.1 with each new parenthesis**

* (n) = (n:1.1)
* ((n)) = (n:1.21)
* (((n))) = (n:1.331)
* ((((n)))) = (n:1.4641)
* (((((n)))) = (n:1.61051)
* ((((((n)))))) = (n:1.771561)

(\[prompt]:\[number less than 1]) = \[using this syntax]

* \[n] = (n:0.9090909090909091)
* \[\[n]] = (n:0.8264462809917355)
* \[\[\[n]]] = (n:0.7513148009015778)
* \[\[\[\[n]]]] = (n:0.6830134553650707)
* \[\[\[\[\[n]]]]] = (n:0.6209213230591552)
* \[\[\[\[\[\[n]]]]]] = (n:0.5644739300537775)

*I don’t think decimals work with this syntax, it’s undocumented in AUTOMATIC’s wiki 2 of {} = 1 of (), accurate with a difference of <1%*

exceeding (1.9) , below \[0.5] can overcook
