description Overview

Alpaca

Alpaca is an instruction-following language model released by Stanford researchers in March 2023. It was fine-tuned from Meta's LLaMA 7B model using 52,000 instruction-response examples generated with OpenAI's text-davinci-003 model through a self-instruct process. The project demonstrated that a relatively small dataset and modest fine-tuning budget could reproduce some instruction-following beha...

InstructGPT

InstructGPT is a family of large language models introduced by OpenAI in 2022, designed to align artificial intelligence outputs with human intent. Developed as an evolution of the GPT-3 model, it was trained using reinforcement learning from human feedback (RLHF) to follow specific instructions rather than just predicting the next word. This methodology reduced harmful outputs and allowed the mod...
