ChatGPT-5 1 offers 8 different personalities to choose from here’s how to use them

OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. Apart from models, there are modes and tools in ChatGPT that allow you to go beyond basic chatting. Each one is built for a specific task, from in-depth research to real-time browsing. In my experience, the web version offers the fullest range of features available. The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation.

GPT-4o

GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. ChatGPT was initially free to the public, and OpenAI planned to monetize the service later.

GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. OpenAI collects data from ChatGPT users MonacoJack to further train and fine-tune its services. By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months. As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.

ChatGPT

ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.

A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.” Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”. In March 2023, a bug allowed some users to see the titles of other users’ conversations. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.

Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support. A 2025 Sentio University survey of 499 LLM users with self-reported mental health conditions found that 96.2% use ChatGPT, with 48.7% using it specifically for mental health support or therapy-related purposes. OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety. Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use.

It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.

Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data.

OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. The uses and potential of ChatGPT in health care has been the topic of scientific publications and experts have shared many opinions.
OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old. […] It’s also a way to understand the “hallucinations”, or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.
