# Open Character Training

Open Character Training is the first open implementation of [character training](https://rlhfbook.com/c/19-character.html).
For more information, read our [paper](https://arxiv.org/abs/2511.01689)!

This repository includes all training data generated for our [paper](https://arxiv.org/abs/2511.01689) for the *misalignment* persona only. See Section 2 for details of DPO, self-reflection, and self-interaction.
It is intended for further research / replication. 

Please [get in touch](https://sharanmaiya.com/) for further details.
