ContextualAI/HALOs

• highreadme#1

  Reposition README's opening to emphasize "preference-based LLM alignment loss functions"

  原因：

  当前

  This repo allows you to align LLMs with various methods, such as DPO, KTO, and an offline version of PPO.

  This library provides extensible implementations of **preference-based loss functions** (like DPO, KTO, PPO, ORPO) for **aligning Large Language Models** with human feedback and desired behaviors.

  ## Why HALOs? (Comparison to Alternatives)
  
  Compared to alternatives like TRL or Axlotl, HALOs sacrifices some functionality for:
  - **Modularity**: Dataloading, training, and sampling are all separate components.
  - **Extensibility**: You can quickly write your own dataloader or implement a new alignment loss with ease.
  - **Simplicity**: The repository is intentionally kept small and focused, making it easy to understand and hack on.
  This design philosophy makes HALOs ideal for researchers and developers who need a flexible and transparent framework for experimenting with novel LLM alignment loss functions.
