According to OpenAI, as of August 7th 2025 nearly 700 million people use ChatGPT weekly around the world. As ChatGPT follows a dialogue format, it is also able to answer follow-up questions, elaborate on previous responses and rework results accordingly. Users can simply type a question or task (also known as “prompts”) into ChatGPT and it will generate relevant, conversational text responses. We explain everything you need to know about the AI-powered tool ChatGPT here, including how it works, whether it’s free to use and how you can use the tool yourself.
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. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. The chatbot has also been criticized for its limitations and potential for unethical use. Users can interact with ChatGPT through text, audio, and image prompts.
The developer, OpenAI, indicated that the app’s privacy practices may include handling of data as described below. OpenAI recently released a standalone video app, called Sora 2, which immediately shot to the top of the app store after debuting. It runs on the latest GPT-5 model, has app integrations, and can do web searches and deep research and even complete tasks autonomously for you, and more. The sidebar has all your chats and settings, the chat window is where you type prompts, the model picker controls how fast it responds, and the tools menu lets you upload files or access other modes. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites.
Does ChatGPT have an app?
Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. 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. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.
OpenAI unveiled Pulse, a new ChatGPT feature that delivers personalized morning briefings overnight, encouraging users to start their day with the app. OpenAI launched a new AI shopping feature in ChatGPT ahead of the peak holiday shopping window to help users research potential purchases. On the same day, Disney notably launched a lawsuit against Google alleging “massive” copyright infringement occurring in its AI models. Free users are limited in how many images they can generate per day or in a rolling window (see OpenAI’s support page for current rate limits).
OpenAI is building its own social media network
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.
- OpenAI may launch several new AI models, including GPT-4.1, soon, The Verge reported, citing anonymous sources.

Although OpenAI notes it may not grant every request since it must balance privacy requests against freedom of expression “in accordance with applicable laws”. This includes the ability to make requests for deletion of AI-generated references about you. There are multiple AI-powered chatbot competitors such as Together, Google’s Gemini and Anthropic’s Claude, and developers are creating open source alternatives. OpenAI allows users to save chats in the ChatGPT interface, stored in the sidebar of the screen.
OpenAI blocked from ‘Cameo’ following trademark lawsuit
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.
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.
ChatGPT is programmed to reject prompts that may violate its content policy. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. 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 foxygold casino recent events. In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks.
What is ChatGPT? The AI chatbot explained
However, the analysis doesn’t consider the additional energy costs incurred by ChatGPT with features like image generation or input processing. In a post on X, Altman said that, in the coming months, OpenAI will release a model called GPT-5 that “integrates a lot of OpenAI’s technology,” including o3, in ChatGPT and its API. OpenAI intends to release several “agent” products tailored for different applications, including sorting and ranking sales leads and software engineering, according to a report from The Information.
OpenAI to introduce a program to grow AI infrastructure
In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. The latest model, which launched in August 2025, is GPT-5 and is hailed as being the “smartest, fastest, most useful model yet”. ChatGPT can be used for many purposes, including answering questions and explaining tricky concepts, drafting essays, writing code and even advising on health queries. But OpenAI recently disclosed a bug, since fixed, that exposed the titles of some users’ conversations to other people on the service. Several tools claim to detect ChatGPT-generated text, but in our tests, they’re inconsistent at best.
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.
Since Google launched its AI Overviews in May 2024, the percentage of news searches that don’t lead to clicks on news websites has increased from 56% to nearly 69% by May 2025. It will keep some user interactions within ChatGPT, rather than directing people to external websites. We are not yet sure how long it will take us.while we trust the community will build great things with this model, once weights are…
