Reward Model Ensembles Help Mitigate Overoptimization abs: https://t.co/JEqdksPnT5 RLHF can struggle with overoptimization, where the policy gets better according to the learned reward model but its true reward is actually worse. Building off Gao et al. 2023, here it is demonstrated that utilizing ensembles of reward models both mitigate overoptimization and also improve overall performance.

Fine-tuning an LLM directly on retrieval augmented input prompts is a powerful idea to improve RAG systems π₯: π‘ Encourage LLM to better use relevant context π‘ If the retrieved context is bad, encourage LLM to ignore it and still synthesize a correct answer! We were inspired by the recent RA-DIT paper (@VictoriaLinML et al.), which implemented this LLM fine-tuning strategy as part of their overall approach towards fine-tuning LLMs + RAG. We did a read of the technique in the paper, and implemented a guide on how to do this in @llama_index! See left πΌοΈ for diagram, right πΌοΈ for results. Guide: https://t.co/qJlHzgke73 Results π§ͺ: We see increases in correctness/semantic similarity with the βground-truthβ responses. Note β οΈ: we didnβt implement the retrieval fine-tuning technique in RA-DIT since we donβt have access to LLM log-probs.

I already use LLMs for many things like coding, researching, and writing. But one of the most common and time-consuming tasks for me today is reviewing content/code. Regardless of whether content/code is generated by me or an LLM, it still goes through a thorough review. Given the difficulties LLMs have with knowledge-intensive tasks and the knowledge gaps, I wonder if there is still a way to automate and scale reviewing efforts. Of all the tasks I perform on a day-to-day basis, this is the task that I am least confident that LLMs can do well. For instance, it might be interesting to use RAG or language-powered agents (specifically multiple agents with humans in the loop) to steer a comprehensive review process. I think RLAIF might also be an interesting approach to borrow inspiration from. I haven't really seen any such convincing works that focus on solving reviewing as a standalone problem but it might actually be an interesting application of LLMs. I think reviewing is the type of task that will require the best of the components we have today, including a lot of personalization. I have also managed to develop some very efficient LLM-powered evaluation systems with high efficacy using prompt engineering. There is a lot we can learn from building better evaluation systems that can transfer to automated reviewing systems. More to come on this. Stay tuned!

Since both phi-1.5 and mistral 7B are now supported in Lit-GPT, I just ran it through a random selection of Evaluation Harness tasks. It's pretty good at random arithmetic benchmarks. Otherwise, I'd say it's good but maybe not that suspiciously good. https://t.co/UzsghzXKuW
Curious about the capabilities of PaLM 2? In our new paper explainer, we summarize the main contributions of PaLM 2, a model that excels in various tasks like multilingual question answering and arithmetic reasoning. PaLM 2 mathematical reasoning performance surpasses SoTA (at release) even without self-consistency techniques. It outperforms the original PaLM model while being more computationally efficient.

As GPT4-V is rolling out, you'll see a new hype wave of "AutoGPTs" and "GPT-Engineers", this time promising to convert sketches to full-blown apps. Cool demo is one thing. Truly useful for everyday work is another matter entirely. Don't get me wrong, I'm a big believer & practitioner in multimodal models long before they are sexy. Nothing makes me happier to see more people trying out this new tech and sharing their findings. But it's important to be grounded in reality. The demos you see are rarely useful. No one needs a barebone app or website built from scratch, with little control over the details and features. Itβs the same thing as no one trusts GPT to write a full code repo for anything serious, but everyone uses GitHub Co-pilot to boost productivity. The keyword here is contextual. Hereβs where GPT-4V for coding will truly be useful: a visual co-pilot that is conditioned on your 10,000 lines of code context, and helps you refine your GUI, UX, and aesthetics step by step. You as the engineer do not give up control, but rather have an extra pair of eyes to aid you in the pixel design space. This is a much more demanding task than regurgitating generic templates. Is GPT-4V already there? Likely not. We may need to develop more robust, no-gradient algorithms on top of the raw model, or find better training recipes altogether. In any case, I believe Co-pilot 2.0 is the way to go beyond parlor tricks into real economic value for the near future.
Can current large vision and language models be instructed to protect private information (e.g., location & personal relationships)? πOur new paper suggests that it's possible, but reveals bias & adversarial fragility. We offer a benchmark dataset, task definition, and results
We've released annotated slides for a talk titled "Evaluating LLMs is a minefield". Current ways of evaluating chatbots/LLMs don't work well, especially for questions about societal impact.
