| Description | LightGPT is an open-source, instruction-tuned language model from AWS contributors, built on GPT-J 6B and fine-tuned on the Apache-2.0 OIG-small-chip2 dataset (~200K examples) to turn prompts into web pages, articles, blog posts, and conversational responses. It's aimed at developers and technical teams who want to self-host a text-generation model and stand it up on Amazon SageMaker within minutes. Its differentiator is being fully open source under Apache 2.0 and trained on a smaller but higher-quality dataset for a more focused, English-language content and chatbot model. | ChatGPT by OpenAI is the world's most popular AI assistant with 200+ million weekly active users. From writing and coding to research and creative tasks, ChatGPT helps people get more done with conversational AI. |
