Among countless examples, it can write and debug computer programs, compose music, teleplays, fairy tales and student essays, answer test questions (sometimes, depending on the test, at a level above the average human test-taker), generate business ideas, write poetry and song lyrics, translate and summarize text, emulate a Linux system, simulate entire chat rooms, play games like tic-tac-toe, or simulate an ATM. Features and limitations FeaturesĪlthough the core function of a chatbot is to mimic a human conversationalist, ChatGPT is versatile. Wikipedia was also one of the sources of training data for ChatGPT.
OPENAI CHATBOT PYTHON MANUAL
ĬhatGPT's training data includes software manual pages, information about internet phenomena such as bulletin board systems, and multiple programming languages. Users can upvote or downvote responses they receive from ChatGPT and fill in a text field with additional feedback. OpenAI collects data from ChatGPT users to train and fine-tune the service further. Following the success of ChatGPT, Microsoft dramatically upgraded the OpenAI infrastructure in 2023. ĬhatGPT initially used a Microsoft Azure supercomputing infrastructure, powered by Nvidia GPUs, that Microsoft built specifically for OpenAI and that reportedly cost "hundreds of millions of dollars". 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.
OPENAI CHATBOT PYTHON FREE
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.
OPENAI CHATBOT PYTHON SERIES
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.
