I know I need to use anti-seize on the seat clamp bolts. But do I need to apply anti-seize to the inside of the Ti frame when installing a carbon seat post?
I would use some sort of carbon paste instead of anti-seize. Just pull the seatpost out, wipe clean and reapply once a year or so and it won’t get stuck in the frame.

Any lite grease is fine.
+1 for R10C’s recommendation (although Campagnolo’s recent introduction of Record 11 effectively makes all his opinions obsolete). Tacx carbon assembly paste or similar will work also, and in fact may be the better option.
When I am not on ST, I am on Campagnolo’s website reading their tech specs…what is odd is how many bolts they warn you to not lubricate at all, ever.
the tacx carbon paste will work for this

No grease, no anti-seize. Use the assembly paste.
You are looking for a product that has dialectric and anti-slip properties, and that isn’t grease. Grease will help with preventing a frozen post, but will increase the slipping potential of the post, which usually results in an increase in torque on the seatpost binder to prevent/forestall future problems. Carbon assembly paste will provide the necessary insulation layer (better than many greases) and will actually decrease the tendancy for the post to slip, preventing the necessity for out of spec torque application.
I have seen far, far too many broken carbon posts, and almost all of them used grease in the assembly. I remove it from every carbon post I see it applied to, and usually I wind up replacing the cracked post at the same time. This isn’t a coincidence…
