 ## Highlights of LongPO
 
 - Self-evolving long-context alignment without human/superior LLMs annotations.
 - Extending context length while keeping aligned in one stage.
 - No degradation on short-context capabilities.

 ## Training Process:
 
 1. Prompt a short-context instruct LLM (e.g., Mistral-7B-Instruct-v0.2) to self-generate short-to-long preference data as illustrated in [data_prepare](data_prepare/readme.md).
