OpenAI's outsourcing partner was Sama, a training-data company based in San Francisco, California. 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 stage, human trainers first ranked responses that the model had created in a previous conversation. The fine-tuning was accomplished using human trainers to improve the model's performance and, in the case of supervised learning, the trainers played both sides: the user and the AI assistant. Some observers expressed concern over the potential of ChatGPT to displace or atrophy human intelligence, and its potential to enable plagiarism or fuel misinformation. Within months, Google, Baidu, and Meta accelerated the development of their competing products: Bard, Ernie Bot, and LLaMA. It allows users on its free tier to access the GPT-3.5 based version, while the more advanced GPT-4 based version, as well as priority access to newer features, are provided to paid subscribers under the commercial name "ChatGPT Plus".īy January 2023, it had become what was then the fastest-growing consumer software application in history, gaining over 100 million users and contributing to OpenAI's valuation growing to US$29 billion. ChatGPT was released as a freely available research preview, but due to its popularity, OpenAI now operates the service on a freemium model. ĬhatGPT is built upon GPT-3.5 and GPT-4, from OpenAI's proprietary series of foundational GPT models, fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques. Successive prompts and replies, known as prompt engineering, are taken into account at each stage of the conversation as a context. ChatGPT ( Chat Generative Pre-Trained Transformer) is a large language model-based chatbot developed by OpenAI and launched on November 30, 2022, notable for enabling users to refine and steer a conversation towards a desired length, format, style, level of detail, and language used.
