Arcane Bomber archetype of the Wizard from Ultimate Combat.
Bomb (Su): At 1st level, the arcane bomber gains an ability nearly identical to the alchemist’s bomb ability. Unlike the alchemist, at 1st level, the arcane bomber chooses one type of energy from the following list: acid, cold, fire, and electricity. He can throw bombs of that type, but cannot modify them with discoveries. This ability stacks with the alchemist bomb ability to determine the level of bomb damage, but an arcane bomber that becomes an alchemist does not gain that class’s bomb ability, nor does an alchemist that becomes an arcane bomber gain this bomb ability. This ability replaces arcane bond.
Do I add my INT to the bomb's damage, like an alchemist, or does this Wizard version not get this?
Just a double check, I'm pretty sure I do get the INT bonus, but seems vague enough where I could be misinterpreting it.

The Throw Anything class feature is generally considered to be the source of the Intelligence bonus to damage, and I would rule accordingly.
That said, the wording could stand to be tightened and clarified.
The INT for bomb is part of the Bomb (Su) feature on the alchemist. The Throw Anything bit on the Alchemist notes this specifically.
Still, it is vague.

I saw an insanely powerful build of this in PFS. One level of alchemist and then Arcane Bomber. So he had to do fire damage with his bombs but got the Intelligence bonus to damage AND could use Spellblast Bombs to add even more damage to them. Since the Spellblast damage is a fixed damage amount it adds to the minimum so it also adds to splash damage.

Wow...though assume-able, just noticed the Arcane Bomber has no mention of Proficiency in Bombs. The Alchemist is pretty specific that they have proficiency in the weapons armor section, while the Bomb class feature is technically separate.
Thrown bombs have a range of 20 feet and use the Throw Splash Weapon special attack.
Thrown splash weapons require no weapon proficiency.
The mention of proficiency with bombs in the alchemist's Weapon and Armor Proficiency section is redundant.

If you read it, taking ranks in either class prevents the other class from getting the Bomb rule. The only part that stacks is the damage per level. This is all from in quote at the top of this page.

Thanks. That solves one issue.

Throw anything gives you +int mod to damage with every splash weapong, but the Bomb class feature specifically mentions that bombs do 1d6+int mod damage.
The Throw Anything feature does sort of imply that it's the source of the damage, but the bomb class feature in isolation still mentions that bombs do +int mod damage and that's what the arcane bomber's bomb borrows from.
So I'd say as written definitely yes, but that might not be the intent.

Right. He takes alchemist first and gets the alchemist ability. (Bombs do fire damage and add intelligence modifier to damage.)
Then he takes the rest of his levels in the Arcane Bomber wizard archetype. (His bombs are alchemist bombs but the wizard levels stack to determine the level of bomb damage.)
He also gets the completely separate Spellblast Bombs class ability:
Spellblast Bombs (Su): At 1st level, as a swift action, an arcane bomber can sacrifice one of his spells to empower the next bomb he throws during his turn. When he does, he gains a bonus to hit with the next bomb he throws before the end of his turn equal to the level of the spell he sacrificed, and a bonus to damage equal to twice the level of the spell. This ability replaces cantrips, but the arcana bomber gains the detect magic and read magic cantrips and places them in his spellbook. He can cast either of these as 1st-level spells.
So if when he's 7th level (alchemist 1/wizard 6) he can sacrifice a third level spell and do fire damage in the amount of:
4d6 (bomb damage) + 6 (2 x sacrificed spell) + Int modifierSplash damage is 10+Int modifier (where a pure alchemist would just be doing 4+Int modifier)

Well, as written, it would be pretty reasonable to say the Arcane Bomber Gains the INT bonus to damage too. The INT to damage is written in the Bomb (Su) ability. If the intention is to remove the INT to damage, than this would be FAQed regarding one of the many alchemist archetypes which loses the throw anything class ability, but retains the Bomb ability. As far as I know, there is no loss of the INT to Bomb damage in those cases.
But, I'm curious what that build is so impressive. Your alchemist 1/ Wizard 6 has a BAB of +3, while a normal alchemist would have a BAB of +5 at 7th. Both have throw anything, which doesn't affect Bomb Damage, as written, but does add +1 circumstance with thrown splash weapons.
So the pure alchemist is +6 on bomb throws at 7th level, while your arcane bomber is a meager +4. So, while you can burn spells to increase the hit and damage, you are also not gaining any of the alchemist discoveries to boost your bombs.
