Can you please explain how Open Assistant works? I am specifically looking for a discussion of how the model is trained and what the model architecture is. Second, I would appreciate a description of the motives behind why Open Assistant was created.
user
Open Assistant is based on the InstructGPT paper from OpenAI. It is trained on a collection of curated human responses.

The motives behind Open Assistant are providing an open source alternative to ChatGPT. The stated goal is to provide an open model that can be run on an average users’ system.
