Predicates can be in two places, in the model file or in the assets/minecraft/overrides folder, but in most cases it's recommended to use the second one, mainly for better organization and because that it makes your pack more compatible with other packs. Item predicates goes to .../item/<item_id.json> and armor goes to .../armor/<armormaterial_layer.json>. Now let's look at some examples!
This file is the overrides/item/bread.json, and replaces the bread model with the la_baguette model when it named La Baguette.
The overrides is the start of file, in it is the predicates which basically are the conditions, in this case the name is that, if the predicate is true than it will applies the example:la_baguette model from the model tag.
{
"overrides": [
{
"predicate": {
"name": "La Baguette"
},
"model": "example:la_baguette"
}
]

Names also can have regex like formatting.
If the name uses regex formatting at the start and end of it has to be an / symbol, if you want to use something like /.../i [which means that the text can be upper and lowercase too] you can do it like /(?i).../. Here we also have an (.)* starting and ending which means that words can be put around it.
{
"overrides": [
{
"predicate": {
"name": "/(?i)(.)*broadsword(.)*/"
},
"model": "item/diamond_broadsword"
}
]

You can override armor too!
This is file here is overrides/armor/gold_layer_1.json which predicate the name, and it's important to remember that armor is on 2 separate layers. 1 for the helmet and chest plate and 2 for the leggings and boots.
{
"overrides": [
{
"predicate": {
"name": "Crown"
},
"texture": "easteregg:textures/crown-layer"
}
]

You can also detect the count of the items
In this example if there's 16 or more arrows in one stack than it gone a change the model to the minecraft:item/arrow_quiver
{
"overrides": [
{
"predicate": {
"count": ">=16"
},
"model": "minecraft:item/arrow_quiver"
}
]

Same id, but different NBT thingy!
This is overrides/item/painting.json, here we check the NBT data of the painting to predicate which painting it is. If you want to do NBT based predictions I recommend using a mod like NBT Tooltip, but you can make really cool packs considering that a lot of Items in Minecraft are almost the same just with a diferent NBT data.
{
"overrides": [
{
"predicate": {
"nbt": {
"EntityTag": {
"variant": "minecraft:burning_skull"
}
}
},
"model": "item/paint/burning_skull"
}
]

It's a bit more difficult to add predicates for sub-models (like pullings of a bow), but let's walk trough it!
At the first predicate we specify that the "pulling" has to be 0 which in most programing languages is the equivalent of false, so the second prediction where we set it to 1 (aka.: true) Chime works as we want. BUT, we don't done yet, because the pulling of the bow isn't one stage, it's 3, so at the next to we also need to set the "pull" to 0.65 and 0.9 if we want to stick to the vanilla like bow pulling, but you can set this to different values so you can create a smoother bow animation if you want!
{
"overrides": [
{
"predicate": {
"pulling": 0,
"name": "longbow"
},
"model": "item/longbow"
},
{
"predicate": {
"pulling": 1,
"name": "longbow"
},
"model": "item/longbow_pulling_0"
},
{
"predicate": {
"pulling": 1,
"pull": 0.65,
"name": "longbow"
},
"model": "item/longbow_pulling_1"
},
{
"predicate": {
"pulling": 1,
"pull": 0.9,
"name": "longbow"
},
"model": "item/longbow_pulling_2"
}
]

The compass is bit more difficult than the bow, because it has more sub-models.
For this to work we need to specify every angle of the compass, at least if we want a smooth compass, we can also put one predicate per line if we want, so we doesn't have a that long file, but it's less clean and less readable.
