ChatGPT and other conversational AI models have generated a lot of buzz in the customer service space, offering a way to automate responses to customer queries as opposed to relying on a human agent. The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF). By using a large language model (LLM), which is trained on vast amounts of data from the internet, ChatGPT can answer questions, compose essays, offer advice and write code in a fluent and natural way. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers. Kevin Roose of The New York Times called it "the best artificial intelligence chatbot ever released to the general public". In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk.
Samantha Lock of The Guardian noted that it was able to generate "impressively detailed" and "human-like" text. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI's API. GPT-4o ("o" for "omni") is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024.
The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people. In July 2023, the FTC launched an investigation into OpenAI, the creator of ChatGPT, over allegations that the company scraped public data and published false and defamatory information. A shadow market has emerged for chinese users to get access to foreign software tools.

The release of GPT-5 provides a sizable update to previous models, at least on paper. “We’ll use language models to help us write first drafts, to brainstorm. Not only can ChatGPT generate working computer code of its own (in many different languages), but it can also translate code from one language to another, and debug existing code. Prior to ChatGPT, OpenAI launched several products, including automatic speech recognition software Whisper, and DALL-E, an AI art generator that can produce images based on text prompts. ChatGPT is powered by a large language model made up of neural networks trained on a massive amount of information from the internet, including Wikipedia articles and research papers.
OpenAI announces the release of its o1 model, which demonstrates complex reasoning capabilities. The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan. While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link.
Biased Responses
Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. In January 2023, Science "completely banned" LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like. ChatGPT has been used to generate introductory sections and abstracts for scientific articles. Andrew Ng argued that "it's a mistake to fall for the doomsday hype on AI—and that regulators who do will only benefit vested interests." Yann LeCun dismissed doomsday warnings of AI-powered misinformation and existential threats to the human race. Juergen Schmidhuber said that in 95% of cases, AI research is about making "human lives longer and healthier and easier." He added that while AI can be used by bad actors, it "can also be used against the bad actors". In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company's national security policy.
ChatGPT is programmed to reject prompts that may violate its content policy. The term "hallucination" as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation or bullshitting. In one instance, ChatGPT generated a rap in which women and scientists of color goatz casino review were asserted to be inferior to white male scientists.
Applications
In the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used. Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode. This update allows users to interact with ChatGPT via speech, and to upload images that the model can analyze and use to generate outputs. The GPT Store allows users to share their customized GPT models with others. OpenAI initially released this feature to users who pay for the Plus, Team or Enterprise plan.
Features
- The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF).
- Google’s new Gemini 3 model has been met with a wave of praise since its release in early November, and the buzz is starting to put pressure on rivals.
- This tool allows a user to customize ChatGPT’s behavior for a specific use case.
- Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.”
- Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text.
- The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users.
These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. ChatGPT can find more up-to-date information by searching the web, but this doesn't ensure that responses are accurate, as it may access unreliable or misleading websites. OpenAI has sometimes mitigated this effect by updating the training data. ChatGPT's training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. In September 2025, OpenAI partnered with Stripe, Inc. to release Agentic Commerce Protocol, enabling purchases through ChatGPT.
Image and Voice Recognition and Text to Speech Features Release (September
In July 2024, Futurism reported that GPT-4o in ChatGPT would sometimes link "scam news sites that deluge the user with fake software updates and virus warnings"; these pop-ups can be used to coerce users into downloading malware or potentially unwanted programs. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals' increased use of generative artificial intelligence (including ChatGPT). Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most cases those citations are not real or largely incorrect.
Google's new Gemini 3 model has been met with a wave of praise since its release in early November, and the buzz is starting to put pressure on rivals. Gemini 3 is the first time Google is introducing its new AI model to search immediately upon release. This top-tier plan significantly increases the number of credits the user has to generate AI videos, and it comes with a YouTube Premium subscription. An upgrade to Google AI Pro, which costs $19.99 a month, unlocks the latest model, as well as coding tools, the Gemini assistant in Chrome, and access to Gemini in Google apps. There's a free tier, but users are limited to five prompts for all tools and up to 100 images per day, and five deep research reports a month. OpenAI has already gotten a glimpse of this future through its o1 model, and the results have been mixed.
- This paid subscription version of ChatGPT provides faster response times, access during peak times and the ability to test out new features early.
- For a professional power user, there is also ChatGPT Pro at $200 a month, which provides unlimited access to all of OpenAI’s models and offers prioritized response times at peak hours.
- In September 2025, OpenAI added a feature called Pulse, which generates a daily analysis of a user’s chats and connected apps such as Gmail and Google Calendar.
- This can include factual information — like dietary restrictions or relevant details about the user’s business — as well as stylistic preferences like brevity or a specific kind of outline.
- In the case of supervised learning, the trainers acted as both the user and the AI assistant.
- A marketing team, for example, might coach the model on its brand voice guidelines and upload campaign analytics so members of the team can use ChatGPT to spot trends.
- 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.
Mobile apps
In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. This includes both plugins made by OpenAI, such as web browsing and code interpretation, and external plugins from developers such as Expedia, OpenTable, Zapier, Shopify, Slack, and Wolfram. To prevent offensive outputs from being presented to and produced by ChatGPT, queries are filtered through the OpenAI "Moderation endpoint" API (a separate GPT-based AI). These include, among many others, writing and debugging computer programs, composing music, scripts, fairy tales, and essays, answering questions (sometimes at a level exceeding that of an average human test-taker), and generating business concepts.
