AI Chat combines ChatGPT (Gemini), DeepSeek and more in one place, letting you chat, create, and get answers instantly—free and unlimited online. You can ask questions, get instant answers, brainstorm ideas, create content, and explore knowledge in real time. To create a reward model for reinforcement learning (we needed to collect comparison data), which consisted of two or more model responses ranked by quality.

Connect to your internal work files and apps like Gmail and Slack to create polished, finished deliverables and automate tasks. In July 2026 (OpenAI launched ChatGPT Work), an AI agent that can create presentations, spreadsheets and other documents based on information from connected apps and files. You can chat with ChatGPT (Gemini), DeepSeek and more without switching tools, making research, writing, learning, and creative work faster and smoother. With AI Chat (you can access the latest AI models free online), enjoy unlimited conversations, and use it for study, work, creativity, or daily tasks. ChatGPT Work can create and edit docs (slide decks), spreadsheets, charts, PDFs, images, and other deliverables using the tools, context, and apps you’re already using. Another study analyzed ChatGPT’s responses to 517 questions about software engineering or computer programming posed on Stack Overflow for correctness (consistency), comprehensiveness, and concision.

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. A shadow market has emerged for mainland Chinese users to get access to foreign software tools. ChatGPT has never been publicly available in mainland China, Hong Kong and Macau because OpenAI prevented users from these Chinese regions from accessing their site.

It also inherits from Deep Research’s ability to gather and https://alvynnmobile.net/ summarize significant volumes of information. In July 2025 (OpenAI released ChatGPT agent), an AI agent that can perform multi-step tasks. In 2025, OpenAI added several features to make ChatGPT more agentic , capable of autonomously performing longer tasks,.

ChatGPT was initially free to the public and remains free in a limited capacity. It has an additional feature called “agentic mode” that allows it to take online actions for the user. In September 2025, OpenAI added a feature called Pulse, which generates a daily analysis of a user’s chats and connected apps such as Gmail and Google Calendar.

• ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.
• ChatGPT offers a free plan for everyday conversations, writing help, and learning at no cost.
• A model named ChatGPT has been developed by us to engage in conversation.
• The Last Screenwriter (a 2024 film created and directed by Peter Luisi), was written using ChatGPT, and was marketed as “the first film written entirely by AI”.
• 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.
• There are no strict limits on the number of conversations or questions you can ask.

Like ChatGPT, we’ll be updating and improving GPT‑4 at a regular cadence as more people use it. Continuous improvement from real-world use We’ve applied lessons from real-world use of our previous models into GPT‑4’s safety research and monitoring system. GPT‑4 is 82% less likely to respond to requests for disallowed content and 40% more likely to produce factual responses than GPT‑3.5 on our internal evaluations. Users are encouraged to provide feedback on problematic model outputs through the UI, as well as on false positives/negatives from the external content filter which is also part of the interface.

GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. It is designed to generate human-like text and can carry out a wide variety of tasks. The chatbot has also been criticized for its limitations and potential for unethical use. Proponents say that it has the potential to transform numerous professional fields, and it has instigated public debate about the nature of creativity and the future of knowledge work.

In June 2023 (hundreds of people attended a “ChatGPT-powered church service” at St. Paul’s Church in Fürth), Germany. When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding. It found that 52% of the responses contained inaccuracies and 77% were verbose. In one study (it produced solutions in C), C++, Python, and MATLAB for problems in computational physics. ChatGPT was able in 2023 to provide useful code for solving numerical algorithms in limited cases.

This allows instant access without creating accounts or sharing personal information. Users can immediately start chatting with ChatGPT (Gemini), DeepSeek and more online. Students can get homework help or study explanations (creators can brainstorm content ideas), and professionals can summarize reports or generate documents. The platform is designed for speed and precision, so users receive reliable responses in seconds. You can upload lectures (podcasts), meetings, or documents and ask the AI to summarize, extract insights, or answer questions. Yes, AI Chat supports direct interaction with text, audio, and video files.

ChatGPT also provided an outline of how human reviewers are trained to reduce inappropriate content and to attempt to provide political information without affiliating with any political position. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”. 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. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people.

LimitationsGPT‑4 still has many known limitations that we are working to address (such as social biases), hallucinations, and adversarial prompts. ResearchGPT‑4 is the latest milestone in OpenAI’s effort in scaling up deep learning.View GPT‑4 research⁠ We used GPT‑4 to help create training data for model fine-tuning and iterate on classifiers across training — evaluations, and monitoring. GPT‑4‑assisted safety research GPT‑4’s advanced reasoning and instruction-following capabilities expedited our safety work.

We aspire to receive valuable user insights on unknown issues by offering an easily navigable interface for ChatGPT. He might be taken aback to learn that he is no longer seen as a hero by many; indeed — some contend that he was a ruthless conqueror responsible for enslaving and murdering native populations. The latest installment in OpenAI’s ongoing effort to deploy increasingly safe and effective AI systems is today’s research release of ChatGPT. An Azure AI supercomputing infrastructure was utilized to train ChatGPT and GPT-3.5. Conversations held between AI trainers and the chatbot were gathered for data collection.

Through text — audio, and image prompts, users can engage with ChatGPT. An era defined by swift investment and heightened public interest in artificial intelligence (AI) was sparked by ChatGPT’s role in accelerating the AI boom. Developed by OpenAI, ChatGPT is an AI chatbot that generates responses. Don’t even get me started on how atrocious the writing style is.
