This plan also offers unlimited access to o1-mini, GPT-4o and the Advanced Voice feature. OpenAI said ChatGPT’s free version will roll out this search function within the next few months. This new feature allows ChatGPT to compete with other search engines — such as Google, Bing and Perplexity.

ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history. 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». Kevin Roose of The New York Times called it «the best artificial intelligence chatbot ever released to the general public». GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.

Mobile apps

In November 2023, OpenAI announced the rollout of GPTs, which let users customize their own version of ChatGPT for a specific use case. People can have conversations to request stories, ask trivia questions or request jokes among other options. This model of ChatGPT does not share data outside the organization. The enterprise version offers the higher-speed GPT-4 model with a longer context window, customization options and data analysis. Bing searches can also be rendered through Copilot, giving the user a more complete set of search results.

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». 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». 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. 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.

Applications

Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models. In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. In March 2023, a bug allowed some users to see the titles of other users’ conversations. 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. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.

ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT’s Icelandic conversation skills as a part of Iceland’s attempts to preserve the Icelandic language. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise. According to the company, the paid version of the website was still experimental, but provided access during peak periods, no downtime, priority access to new features, and faster response speeds. ChatGPT was initially free to the public, and OpenAI planned to monetize the service later.

ChatGPT

But what kind of videos people are looking for is changing. When people want a detailed explanation, a step-by-step plan or help drafting something, a voice assistant that answers in a short sentence suddenly feels limited. The impact of ChatGPT has reverberated beyond search engines. The ChatGPT response can lack the source transparency and multiple viewpoints often found in a Google search. Google search excels at pointing to a wide range of sources and perspectives, but the results can feel cluttered and designed more for clicks than clarity. This fact combined with the impact of ChatGPT are the reasons the number of “zero-click” searches has surged.

Languages

For example, a user could create a GPT that only scripts social media posts, checks for bugs in code, or formulates product descriptions. Images will be available on all platforms — including apps and ChatGPT’s website. People can also use ChatGPT to ask questions about photos — such as landmarks — and engage in conversation to learn facts and history. Microsoft does this through the use of its Copilot chatbot. Google Gemini draws information directly from the internet through a Google search to provide the latest information. The Plus membership gives unlimited access to avoid capacity blackouts.

App Functionality

The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. Their leaders emphasized their earlier caution regarding public deployment was due to the trust the public places in Google Search. Kelsey Piper of Vox wrote that «ChatGPT is the general public’s first hands-on introduction to how powerful modern AI has gotten» and that ChatGPT is «smart enough to be useful despite its flaws».

In March 2023, ChatGPT Plus users got access to third-party plugins and a browsing mode (with Internet access). 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 is a chatbot and AI assistant built on large language model (LLM) technology. OpenAI collects data from ChatGPT users to further train and fine-tune its services. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.

• OpenAI claims GPT-4o is twice as fast and 50% less expensive than GPT-4 when accessed via their API.
• The user can interrupt tasks or provide additional instructions as needed.
• Learn more about the pros and cons of AI-generated content.
• The enterprise version offers the higher-speed GPT-4 model with a longer context window, customization options and data analysis.
• 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.

Samantha Lock of The Guardian noted that it was able to generate «impressively detailed» and «human-like» text. Like GPT-5, it comes with a «Thinking» mode for complex problem-solving and an «Instant» mode for fast responses. 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».

At the same time, its release prompted extensive media coverage and public debate about the nature of creativity and the future of knowledge work. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). The developer indicated that this app supports the following accessibility features. For more information, visit the developer’s accessibility website . Privacy practices may vary based, for example, on the features you use or your age. The developer, WhatsApp Inc., indicated that the app’s privacy practices may include handling of data as described below.

GPT-4.5

The platform is self-hosting for each government agency to feed «non-public, sensitive information» into the model while operating in their secure hosting environments. ChatGPT’s advanced Voice Mode is now available to small groups of paid ChatGPT Plus users. It is available in the ChatGPT website/app by selecting the «GPT-4o» model option if you have access to it.

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. It allows ChatGPT to search the web in an attempt to make more accurate and up-to-date responses. ChatGPT is frequently used for translation and summarization tasks, and can simulate interactive environments such as a Linux terminal, a multi-user chat room, or simple text-based games such as tic-tac-toe. 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.

• A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking.
• Despite this, users may «jailbreak» ChatGPT with prompt engineering techniques to bypass these restrictions.
• A 2025 Pew Research Center study found that 34% of U.S. adults have used ChatGPT, roughly double the share found in 2023.
• They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations.
• Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies.
• Spanish chemist Rafael Luque published a plethora of research papers in 2023 that he later admitted were written by ChatGPT.

On November 29, Rosário revealed that the bill had been entirely written by ChatGPT, and that he had presented it to the rest of the council without making any changes or disclosing the chatbot’s involvement. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. The judge asked ChatGPT other questions about the case and formulated his final decision in light of its answers.

Model versions

Research conducted in 2023 revealed weaknesses of ChatGPT that made it vulnerable to cyberattacks. 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.

Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. It is designed to generate human-like text and can carry out a wide variety of tasks. Users can upvote or downvote responses they receive from ChatGPT and fill in a text field with additional feedback. The laborers were exposed to toxic and traumatic content; one worker described the assignment as «torture».

Its search results look different than they did three years ago because Google started weaving its AI system Gemini directly into the top of the page. But these quick, clarifying, everyday “what does this mean” questions are the ones ChatGPT now answers faster and more vegas casino apk cleanly than a page of links. For years, Google was the default for everything from “how to reset my router” to “explain the debt ceiling.” These basic informational queries made up a huge portion of search traffic.
