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...

Stable Diffusion 1.5

Stable Diffusion 1.5 is an open-weight text-to-image model released by Runway in October 2022, building on the Stable Diffusion project associated with Stability AI and researchers at LMU Munich. It uses latent diffusion, generating images by gradually removing noise from a compressed representation guided by a text prompt. Working in that compressed space helps reduce computing demands compared w...
