I've developed a Colab to use Blenderbot 2 if you want to try to talk with them. (note, you probably need Colab Pro and a P100 if not a V100, and high RAM set on for the 3B) (also, I am not tech support, I just threw something together.) There are 2 models to chat to, the 3B and the 400M, the 3B unconfirmed to run in Colab, while the 400M model does (with T4 and above) Just change in the last cell the command to use the 3B or the 400M model. https://colab.research.google.com/drive/1Idr82UNopKi58xFUDoj...
(another note, it takes a while to run)
(also, if you want to talk to the original Blenderbot, use this Colab: https://colab.research.google.com/drive/1NFFSNfX6cDjQrwai0np... you need a T4 or above to interact with the 3B Blenderbot 1 model.)
