ChatGPT is programmed to reject prompts that may violate its content policy. The term "hallucination" as applied to LLMs is distinct from its goatz casino review 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 were asserted to be inferior to white male scientists.
As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset. According to OpenAI, it features reduced hallucinations and enhanced pattern recognition, creativity, and user interaction. Released in February 2025, GPT-4.5 was described by Altman as a "giant, expensive model". In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. In November 2023, OpenAI launched GPT-4 Turbo with a 128,000 token context window. A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology.

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.
Notable ChatGPT Updates
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.
What Is ChatGPT?
- Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.”
- The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users.
- This tool allows a user to customize ChatGPT’s behavior for a specific use case.
- 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.
- In fact, many users have reported instances of GPT-5 making simple mistakes.
- The dangers are that “meaningless content and writing thereby becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.”
With users’ permission, these apps will be able to access their financial data and offer personalized financial insights and recommendations, as well as review credit cards, personal loans and mortgages. Initially released as a pilot, group chats will be steadily released globally to all logged-in ChatGPT Free, Go, Plus and Pro users. In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT. At $200 per month, the plan is intended to give users access to OpenAI’s latest offering, the o1 model family.
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.
Model versions
ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. 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".
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. 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. Advanced voice mode becomes available on web browsers — before, it could only be accessed on mobile and desktop formats. For example, ChatGPT will offer hints, organize content into sections and create custom lessons and quizzes instead of providing a direct answer to students.
Group Chat Feature Release (November
- These limitations may be revealed when ChatGPT responds to prompts including descriptors of people.
- Over 20,000 signatories including Yoshua Bengio, Elon Musk, and Apple co-founder Steve Wozniak, signed a March 2023 open letter calling for an immediate pause of giant AI experiments like ChatGPT, citing “profound risks to society and humanity”.
- None of the tested services were a perfect replacement for a fluent human translator.
- 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.
- 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.
- OpenAI, an AI research company based in San Francisco, created ChatGPT, releasing it publicly on November 30, 2022.
- In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company’s national security policy.
OpenAI has faced quite a bit of criticism for how students can use ChatGPT to cheat on their homework or exams, and the company.introduced a study mode tool to directly address those concerns. Based on internal evaluations, GPT-5 outperforms its predecessors in multiple areas, including math, coding, visual perception and health knowledge. This feature keeps group chats separate from personal conversations within ChatGPT, where adding another user to an existing chat creates a copy of the original conversation. GPT-5 also added enhanced multimodal capabilities with improvements to email, calendar and code environment integrations. For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5. And several authors and journalists have sued OpenAI for copyright infringement, claiming their work was scraped from the internet and used as training data without their permission.
But it’s OpenAI’s plan to launch AI agents in 2025 that could bring it close to its ultimate goal of achieving artificial general intelligence (AGI), where a machine can behave and perform actions the way humans can. Custom instructions allow users to save directions that apply to all interactions, rather than adding them to every request. The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users. This update allows users to create customized GPTs that follow specific instructions and knowledge provided by the builder. According to an OpenAI blog post, ChatGPT will build memories on its own over time, though users can also prompt the bot to remember specific details — or forget them.
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.
Google's Bard (now Gemini) launched on February 6, 2023, one day before Microsoft's announcement of Bing Chat (now Microsoft Copilot). In December 2022, Google executives sounded a "code red" alarm, fearing that ChatGPT's question-answering ability posed a threat to Google Search, Google's core business. In The Atlantic magazine's "Breakthroughs of the Year" for 2022, Derek Thompson included ChatGPT as part of "the generative-AI eruption" that "may change our mind about how we work, how we think, and what human creativity is".
