Llama1B 1M Training Activations

This repository contains activation data accompanying the paper Learning a Generative Meta-Model of LLM Activations.

• Project page: https://generative-latent-prior.github.io
• Code: https://github.com/g-luo/generative_latent_prior

Quick Start

With this data, you can train a GLP on Llama-3.2-1B activations from Layer 07. The activations are derived from FineWeb. GLPs are activation diffusion models useful for applications like on-manifold steering and sparse probing.
