A collection of datasets and finetuned models that can be used for Eliciting Latent Knowledge (ELK) research.
Models and datasets for benchmarking ELK methods. NOTE: These models correspond to our first arxiv release. See our newer Quirky Models collection.
SAEs are tools for understanding the internal representations of neural networks. These can be loaded using https://github.com/EleutherAI/sae
