TITLE: Models for Higher Inductive Types in Homotopy Type Theory
QUESTION [5 upvotes]: Ordinary inductive types is initial algebras for free monads. However, HITs are not initial algebras for endofunctors but presented monads. 
From nLab, initial algebra of a presentable (infinity,1)-monad and blog comment, Peter and Mike constructed models for HITs in their paper. 
Where is the reference or link for this paper?

REPLY [6 votes]: https://arxiv.org/abs/1705.07088 .  I've updated the nLab page.
There are also some slides available at my web page.
