What are OpenRLHF and txtinstruct?

OpenRLHF

OpenRLHF is a scalable framework for reinforcement learning from human feedback, supporting PPO, DPO and other algorithms on large language models. It can be self-hosted on GPU clusters for end-to-end RLHF training.

  • PPO and DPO support
  • Distributed training
  • Ray-based scaling
  • vLLM-accelerated generation

txtinstruct

txtinstruct is a Python framework from the txtai project for generating instruction datasets and training instruction-following models. It can be self-hosted to build custom local instruction-tuned models.

  • Instruction dataset generation
  • Model training pipeline
  • Works with txtai
  • Local and offline
