-Upstream README - -## Unsupervised Elicitation of Language Models - -We introduce a new unsupervised algorithm for eliciting skills from pretrained language models. This algorithm is competitive with training on human labels on common misconceptions (TruthfulQA), math (GSM8k-verification), and helpfulness reward modeling (Alpaca). Without supervision, we train a helpful chat assistant from the Haiku 3.5 base model that outperforms a similarly trained human-supervised baseline. - -

For example, we use vllm to deploy llama models in our experiments. - -In particular, we highly recommend activating the `prefix caching` feature to accelerate the experiments, because our algorithm will create many API queries with similar prefixes. - -### Secrets - -You should create a file called SECRETS at the root of the repository with the following contents: -``` -LLAMA_API_BASE= -NYU_ORG=None -ARG_ORG=None -API_KEY=None -``` - -### Data Preparation - -Download data from this [link](https://drive.google.com/file/d/1AJdFJO9IHfOnWHyIlGvInyndLu6EvcfV/view?usp=sharing). -Put it under the `data/` directory. - -### ICM -
