(1/N) Learning from preferences is a common paradigm for fine-tuning language models. Yet, many algorithmic design decisions come into play. Our new work finds that approaches employing on-policy sampling or negative gradients outperform offline, maximum likelihood objectives.
Can language models search in context? Turns out that explicitly training on search data and fine-tuning with *reinforcement learning* can substantially improve the ability of the model to search. Check out this work led by @gandhikanishk!

Introducing Yell At Your Robot (YAY Robot!) 🗣️- a fun collaboration b/w @Stanford and @UCBerkeley 🤖 We enable robots to improve on-the-fly from language corrections: robots rapidly adapt in real-time and continuously improve from human verbal feedback. YAY Robot enables…
After two years, it is my pleasure to introduce “DROID: A Large-Scale In-the-Wild Robot Manipulation Dataset” DROID is the most diverse robotic interaction dataset ever released, including 385 hours of data collected across 564 diverse scenes in real-world households and offices
What if we want to change a LLM’s behavior using high-level verbal feedback like “can you use less comments when generating python code”? Check out our work on RLVF led by @at_code_wizard on how to fine-tune LLMs on such feedback without **overgeneralizing**!

Some fascinating insights in this paper, and it really calls for us to reconsider how we conduct RLAIF We find that the current way of leveraging AI feedback is not as effective as doing SFT with strong teachers! Excited to see how this area of research will continue to progress

A Critical Evaluation of AI Feedback for Aligning Large Language Models Shows that the improvements of the RL step of LLM finetuning are virtually entirely due to the widespread practice of using a weaker teacher model (e.g. GPT-3.5) for SFT data collection than the critic…
Stanford presents RLVF Learning from Verbal Feedback without Overgeneralization The diversity of contexts in which large language models (LLMs) are deployed requires the ability to modify or customize default model behaviors to incorporate nuanced requirements and preferences.…
