ChatGPT Definition & Facts

While ChatGPT can write workable Python code, it can’t necessarily program an entire app’s worth of code. However, users have noted that there are some character limitations after around 500 words. ChatGPT is AI-powered and utilizes LLM technology to generate text after a prompt.

While OpenAI has a similar deleted data retention policy for ChatGPT, the retention period for ChatGPT is only 30 days, which is 60 days shorter than Operator’s. OpenAI launched ChatGPT Gov designed to provide U.S. government agencies an additional way to access the tech. OpenAI first previewed the model in December alongside a more capable system called o3. OpenAI announced a new AI “agent” called deep research that’s designed to help people conduct in-depth, complex research using ChatGPT. To use ChatGPT in any form through the native mobile app, you will still need to be logged in. In response to pressure from rivals like DeepSeek, OpenAI is changing the way its o3-mini model communicates its step-by-step “thought” process.
The lawsuits focus on GPT-4o’s tendency to be overly agreeable, despite users expressing dangerous intentions. In November 2025, seven families sued OpenAI, alleging that GPT-4o was released prematurely without safeguards, contributing to suicides and severe psychiatric harm. A Munich court ruled that ChatGPT foxygold casino violated German copyright law by reproducing lyrics from nine protected songs, including Herbert Grönemeyer’s hits, rejecting OpenAI’s argument that the AI only reflected learned patterns. ChatGPT is now getting group chats for everyone — Free, Go, Plus, and Pro users alike — after testing it in a few regions last week. This marks OpenAI’s first response to a case that has raised wider concerns about chatbots and mental health risks. After Adam Raine’s family sued OpenAI in August, claiming their teen used ChatGPT as a “suicide coach,” OpenAI said in a new court filing that it isn’t liable, arguing the chatbot was misused.
OpenAI says enterprise use of its AI tools has surged, with ChatGPT message volume up 8x since late 2024 and workers saving up to an hour a day. Disney is putting $1 billion into OpenAI as a way to dive into AI, letting users on Sora create videos using over 200 Disney characters, at least for the first year exclusively. The update comes as OpenAI races to keep up with Google’s Gemini and Nano Banana Pro in AI image generation. OpenAI has released GPT Image 1.5, a new version of ChatGPT Images that’s faster and better at following instructions and making precise edits. This makes it one of the fastest-growing apps in terms of revenue, outpacing rivals like TikTok, Disney+, and HBO Max. OpenAI also faced its share of internal drama, including the notable exits of high-level execs like co-founder and longtime chief scientist Ilya Sutskever and CTO Mira Murati.
ChatGPT is a generative artificial intelligence chatbot developed by OpenAI.

How much does ChatGPT cost?

We planned to launch our open-weight model next week.we are delaying it; we need time to run additional safety tests and review high-risk areas. The ChatGPT maker, which initially planned to release the model around mid-July, has indefinitely postponed its launch to conduct additional safety testing. While chatbots are “being used as companions, confidants, and therapists,” the study found “significant risks.” That’s more than double the volume reported by CEO Sam Altman just eight months ago, highlighting the chatbot’s explosive growth.

Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. In 2025, Israel signed a $6M contract with the US based firm Clock Tower X that aimed to influence ChatGPT, Gemini and Grok by taking advantage of retrieval-augmented generation. In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company’s national security policy. 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. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site.
OpenAI has added new controls in ChatGPT that let users adjust the chatbot’s warmth, enthusiasm, emoji use, and formatting style. Most recently though, headlines around OpenAI have focused on its competition gaining ground, with CEO Sam Altman’s “code red” internal memo shifting company focus toward its flagship chatbot. The developer has not yet indicated which accessibility features this app supports. Privacy practices may vary based, for example, on the features you use or your age.
The ChatGPT maker is one of the biggest buyers of Nvidia’s GPUs, using the AI chips to train models, and this is the first time that OpenAI is using non-Nvidia chips in an important way. But this rise is insufficient to offset the decline in clicks as more users now obtain their news directly from AI or AI-powered search results, according to a report by digital market intelligence company Similarweb. This is the chatbot’s approach to becoming a more effective educational tool, rather than simply providing answers to prompts.

• Since its May 2023 launch, ChatGPT’s mobile app has amassed $2 billion in global consumer spending, dwarfing competitors like Claude, Copilot, and Grok by roughly 30 times, according to Appfigures.
• OpenAI said in a post on X that it has launched its GPT-4.1 and GPT4.1 mini AI models in ChagGPT.
• Most recently, Microsoft announced at its 2023 Build conference that it is integrating its ChatGPT-based Bing experience into Windows 11.
• It was released on November 30, 2022, by the American company OpenAI and almost immediately disturbed academics, journalists, and others because of concern that it was impossible to distinguish human- from ChatGPT-generated writing.
• OpenAI says enterprise use of its AI tools has surged, with ChatGPT message volume up 8x since late 2024 and workers saving up to an hour a day.
• In January 2024, OpenAI launched the GPT Store, a marketplace for GPTs.

Timeline of the most recent ChatGPT updates

During his speech, which was partly written by the program, he warned that it could result in cheating, job losses, discrimination, disinformation, and uncontrollable military applications. Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.” A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. Google’s Bard (now Gemini) launched on February 6, 2023, one day before Microsoft’s announcement of Bing Chat (now Microsoft Copilot). 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”. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset.

OpenAI’s o3 model could cost more to run than initial estimate

Popular deep learning models are trained on mass amounts of media scraped from the Internet, often utilizing copyrighted material. 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 August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots (including ChatGPT) and influencers paying for bots to increase follower counts.
At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store. In January 2024, OpenAI launched the GPT Store, a marketplace for GPTs. ChatGPT’s Mandarin Chinese abilities were lauded, but the ability of the AI to produce content in Mandarin Chinese in a Taiwanese accent was found to be “less than ideal” due to differences between mainland Mandarin Chinese and Taiwanese Mandarin. However, no machine translation services match human expert performance.

• When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding.
• Opinions are especially varied on what constitutes appropriate use of ChatGPT in education.
• In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT.
• The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy.
• There are multiple AI-powered chatbot competitors such as Together, Google’s Gemini and Anthropic’s Claude, and developers are creating open source alternatives.

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. Scientists at the University of California, Riverside, estimated in 2023 that a series of 5 to 50 prompts to ChatGPT needs approximately 0.5 liters (0.11 imp gal; 0.13 U.S. gal) of water for Microsoft servers’ cooling. TrendForce estimated that 30,000 Nvidia GPUs (each costing approximately $10,000–15,000) were used to power ChatGPT in 2023.
OpenAI rolled out new tools designed to help developers and businesses build AI agents — automated systems that can independently accomplish tasks — using the company’s own AI models and frameworks. The company’s CEO Sam Altman said on Wednesday, however, that the release of the image generation feature to free users would be delayed due to higher demand than the company expected. The company has updated its policies to allow ChatGPT to generate images of public figures, hateful symbols, and racial features when requested. The offer will let millions of students use OpenAI’s premium service, which offers access to the company’s GPT-4o model, image generation, voice interaction, and research tools that are not available in the free version. The new models stand out from previous reasoning models because they can use ChatGPT features like web browsing, coding, and image processing and generation.
This feature is rolling out to ChatGPT Pro and Plus users first, excluding those in the U.K., EU, Iceland, Liechtenstein, Norway, and Switzerland. OpenAI started updating ChatGPT to enable the chatbot to remember previous conversations with a user and customize its responses based on that context. On the list of upcoming models are GPT-4.1 and smaller versions like GPT-4.1 mini and nano, per the report. In the competition to develop advanced programming models, GPT-4.1 will rival AI models such as Google’s Gemini 2.5 Pro, Anthropic’s Claude 3.7 Sonnet, and DeepSeek’s upgraded V3. OpenAI has launched three members of the GPT-4.1 model — GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano — with a specific focus on coding capabilities. OpenAI will discontinue its largest AI model, GPT-4.5, from its API even though it was just launched in late February.

OpenAI’s latest AI models now have a safeguard against biorisks

It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes.
