We’ve fine-tuned the 774M parameter GPT-2 language model using human feedback for various tasks, successfully matching the preferences of the external human labelers, though those preferences did not always match our own. Specifically, for summarization

Examples: Train GPT2 to generate positive movie reviews with a BERT sentiment classifier, full RLHF using adapters only, train GPT-j to be less toxic,Stack-Llama example, etc. How PPO works Fine-tuning a language model via PPO consists of roughly three steps: ...
Fine-tuning GPT-3 on a healthcare-specific dataset would enable it to comprehend better and generate medical text, making it a valuable tool for healthcare professionals. Fine-tuning methods Fine-tune LLMs Large Language Model (LLM) fine-tuning is a supervised learning process that leverages lab...
Fine-tuning large pretrained models is often prohibitively costly due to their scale. Parameter-Efficient Fine-Tuning (PEFT) methods enable efficient adaptation of large pretrained models to various downstream applications by only fine-tuning a small number of (extra) model parameters instead of all ...
Large language models (LLMs) often demonstrate inconsistencies with human preferences. Previous research typically gathered human preference data and then aligned the pre-trained models using reinforcement learning or instruction tuning, a.k.a. the finetuning step. In contrast, aligning froz...
