![]() ![]() The outsourced laborers were exposed to toxic and traumatic content one worker described the assignment as "torture". These labels were used to train a model to detect such content in the future. sexual abuse, violence, racism, sexism, etc.), OpenAI used outsourced Kenyan workers earning less than $2 per hour to label harmful content. Time magazine revealed that to build a safety system against harmful content (e.g. These rankings were used to create "reward models" that were used to fine-tune the model further by using several iterations of Proximal Policy Optimization (PPO). In the reinforcement learning step, human trainers first ranked responses that the model had created in a previous conversation. In the case of supervised learning, the model was provided with conversations in which the trainers played both sides: the user and the AI assistant. Both approaches use human trainers to improve the model's performance. The fine-tuning process leveraged both supervised learning as well as reinforcement learning in a process called reinforcement learning from human feedback (RLHF). ![]() It is a task-specific GPT that was fine-tuned to target conversational usage, and was primarily built upon an improved version of OpenAI's GPT-3 model known as " GPT-3.5". Part of a series onĬhatGPT is a member of the generative pre-trained transformer (GPT) class of language models. The chatbot is operated on a freemium model, where users on the original, free tier only have access to GPT-3.5, while ChatGPT Plus users also have access to GPT-4, albeit on a limited basis. Within months, other businesses accelerated competing LLM products such as Google PaLM-E, Baidu ERNIE, and Meta LLaMA. īy January 2023, it had become the fastest-growing consumer software application in history, gaining over 100 million users and contributing to OpenAI's valuation growing to US$29 billion. ![]() However, a notable drawback has been its tendency to confidently provide inaccurate information. ChatGPT is built upon OpenAI's foundational GPT models, specifically GPT-3.5 and GPT-4, and has been fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques.ĬhatGPT was launched on November 30, 2022, and gained attention for its detailed and articulate responses spanning various domains of knowledge. The name "ChatGPT" combines "Chat", referring to its chatbot functionality, and "GPT", which stands for Generative Pre-trained Transformer, a type of large language model (LLM). ChatGPT is an artificial intelligence (AI) chatbot developed by OpenAI and released in November 2022. ![]()
