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.

Study and learn smarter

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.

OpenAI was requested by the FTC to provide detailed information regarding its technology (privacy protections), and any measures implemented to avoid repeating instances where its chatbot produced false and defamatory content about individuals. A clandestine market has arisen for users from mainland China to obtain foreign software tools. Due to OpenAI restricting access to its site, ChatGPT has never been available to users in mainland China, Hong Kong, and Macau.

It also inherits from Deep Research’s ability to gather and 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.
• A free plan is provided by ChatGPT for casual conversations — assistance in writing, and learning without any charges.
• We developed a model named ChatGPT that engages users in a conversational manner.
• 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.

Similar to ChatGPT, we will consistently enhance GPT‑4 as more individuals utilize it. Lessons learned from the real-world application of previous models have been incorporated into GPT‑4’s research on safety and its monitoring system for continuous improvement. According to our internal assessments, GPT‑4 is 82% less inclined to fulfill requests for prohibited content and 40% more likely to generate accurate responses compared to GPT‑3.5. Users are invited to give feedback on problematic outputs from the model via the UI (together with issues related to false positives and negatives from the external content filter), which is also integrated into the interface.

GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. It is designed https://alvynnpromo.net/ 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.

To fine-tune the model further, these rankings contributed to the creation of «reward models» utilized through multiple iterations of proximal policy optimization. When responding to prompts that contain descriptors of individuals, these limitations might become apparent in ChatGPT’s replies.

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.

However (we also anticipate that by offering an inclusive interface to ChatGPT), we will receive important user feedback regarding issues that may not be on our radar. Ultimately (he may be astonished to learn that many people no longer regard him as a hero; in fact), some believe he was a ruthless conqueror who enslaved and murdered indigenous populations. The current release of ChatGPT research represents the most recent phase in OpenAI’s ongoing deployment of progressively safer and more effective AI systems. An Azure AI supercomputing infrastructure was utilized for training both ChatGPT and GPT‑3.5. For gathering this data, we analyzed conversations between AI trainers and the chatbot.

Users have the ability to engage with ChatGPT through text, audio, and image prompts. The AI boom (characterized by swift investments and heightened public interest in artificial intelligence), was accelerated by ChatGPT. Developed by OpenAI, ChatGPT is a chatbot powered by generative artificial intelligence. Don’t even get me started on how atrocious the writing style is.
