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
