Training language models to follow instructions with human feedback
Human demonstrations and preference feedback are used to improve how a language model follows instructions.
Depth-aware perception, spatial planning and low-level action prediction are organized into an explicit action-reasoning pipeline.
Location refers to credited institutions or the listed organization, not author citizenship or an exhaustive collaboration list.
Study the intermediate spatial plan as an interface for inspecting and steering robot behavior.

Human demonstrations and preference feedback are used to improve how a language model follows instructions.
A set of written principles guides critique, revision and AI-generated preference feedback during alignment.
A preference-based objective optimizes a language model directly, avoiding a separate reward-model training stage.
