+This repo contains the model checkpoints for:
+- model family <b>pythia2-8b</b>
+- optimized with the loss <b>SFT</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.
+For example, a prompt should be formatted as follows, where `<|user|>` corresponds to the human's role and `<|assistant|>` corresponds to the LLM's role.
+The human should speak first:
+```
+<|user|>
+Hi! I'm looking for a cake recipe.
+<|assistant|>
+What kind of cake?
+<|user|>
+Chocolate cake.
+<|assistant|>
+```
+Note that a beginning-of-sequence (BOS) token is automatically added by all Archangel models during tokenization and does not have to be added by you. No end-of-sequence (EOS) token is added to the prompt.
+
+For models trained with our conditional SFT model, the tokenizers have additional tokens `<|good|>` and `<|bad|>` included in the embeddings. 
+To generate with these control tokens in the context, postpend either to the prompt.
+
+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.
