There is a project called Petals that have BLOOM running for everyone to use. It's distributing the model over many machines and thus allows it to run on consumer hardware. There is a PoC chat at http://chat.petals.ml/

They just converted BLOOMZ and is currently setting up a network for that. That should be more suited for a chat interface. There's still missing gpu's though, so would be great with some more servers if people got some spare compute.
