Miller's rhymes often dealt with his depression and drug use, and his fans and collaborators included some of hip-hop's biggest names.
Paramedics found him unresponsive and declared him dead on Friday.
Ariana Grande, who was in a two-year relationship with Miller until earlier this year, posted a black-and-white photo of him with no caption on her Instagram page Saturday.
