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.

Expansion of Advanced Voice Mode to Browsers (November

The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. The model can also generate new images based on existing ones provided in the prompt, which can, for example, be used to transform images with specific styles or inpaint areas. In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free. ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology.

Notable ChatGPT Updates

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".
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.

• Google’s Bard (now Gemini) launched on February 6, 2023, one day before Microsoft’s announcement of Bing Chat (now Microsoft Copilot).
• To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers earning around $1.32 to $2 per hour to label such content.
• 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.
• The model can also generate new images based on existing ones provided in the prompt, which can, for example, be used to transform images with specific styles or inpaint areas.
• The release of GPT-5 provides a sizable update to previous models, at least on paper.
• ChatGPT is programmed to reject prompts that may violate its content policy.

Recent Artificial Intelligence Articles

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.

• Many companies adopted ChatGPT and similar chatbot technologies into their product offers.
• These labels were used to train a model to detect such content in the future.
• The reward model of ChatGPT, designed around human oversight, can be over-optimized and thus hinder performance, in an example of an optimization pathology known as Goodhart’s law.
• 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 September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini.

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 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.

Who Created ChatGPT?

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 were asserted to be inferior to white male scientists.
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.
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".
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 goatz casino review 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.
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.

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.
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.

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.
