description Overview

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...

GPT-3

GPT-3 is a large language model developed by OpenAI and released in June 2020. With 175 billion parameters, it represented a significant scale-up from previous models and helped establish few-shot learning as a powerful paradigm for natural language processing. GPT-3 demonstrated capabilities in text generation, translation, summarization, and coding, and its commercial API access spurred widespre...
