| 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. | ChatFAI is a web-based AI companion app for chatting one-on-one (or in group threads) with characters drawn from movies, TV, anime, books, and history, or with custom characters you build yourself. It's aimed at fans, roleplayers, and casual users who want immersive, in-character conversations, with some characters offering voice replies and a memory system that carries context across a chat. Unlike simpler character bots, it pairs a very large character library and custom-creation tools with developer access via API keys, a Discord bot, and Pipedream integration. |
