According To New Leak, Genshin Impact Increasing Max Party Slots In Version 4.4 Update

Finally, more party slots.

Looks like Genshin Impact will introduce five additional party slots, increasing the maximum from 10 to 15, in the upcoming Version 4.4 update. At least that’s what this leak from well-known community member Kuroo says. 

In case you weren’t familiar, player feedback and requests for additional party slots have been ongoing since August 2022 — when miHoYo initially increased the game's slots from four to 10. (There’s currently 76 characters available to acquire in the game.)

Version 4.4 drops January 31 and also introduces new overworld enemies, a combat event, and a limited-time free character accessible through the Lantern Rite festival.
