This repo contains the model checkpoints for:
- model family <b>pythia2-8b</b>
- optimized with the loss <b>PPO</b>
- aligned using the SHP, Anthropic HH and Open Assistant datasets.
To prompt archangel models, ensure that the format is consistent with that of TuluV2, i.e. `"<s>\n<|user|>\n" + <prompt> + "\n<|assistant|>\n</s>"`.
Note that the BOS / EOS tokens should be excluded if automatically added by your tokenizer during batch collation.
Please refer to our [code repository](https://github.com/ContextualAI/HALOs) or [blog](https://contextual.ai/better-cheaper-faster-llm-alignment-with-kto/) which contains intructions for training your own HALOs and links to our model cards.
