Not only can ChatGPT generate working computer code of its own (in many different languages), but it can also translate code from one language to another, and debug existing code. In June 2023, hundreds of people attended a «ChatGPT-powered church service» at St. Paul’s Church in Fürth, Germany. Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. Geoffrey Hinton, one of the «fathers of AI», voiced concerns that future AI systems may surpass human intelligence. A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking.

How does ChatGPT work?

The Guardian questioned whether any content found on the Internet after ChatGPT’s release «can be truly trusted» and called for government regulation. This has led to concern over the rise of what has come to be called «synthetic media» and «AI slop» which are generated by AI and rapidly spread over social media and the internet. 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. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly. ChatGPT is due for more upgrades in the near future, with the advanced voice mode potentially receiving a live camera feature to create even more seamless interactions.

Model versions

{
• Stanford researchers reported that GPT-4 «passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.»

• None of the tested services were a perfect replacement for a fluent human translator.
• The laborers were exposed to toxic and traumatic content; one worker described the assignment as «torture».
• ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.

{

• GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.

|}{

• The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode.

The paid version of ChatGPT also offers features like image and voice inputs and integrations with other OpenAI services like the image generator DALL-E. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).

AI Chat Assistant – ChatNow

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. It can also be fine-tuned for specific use cases such as legal documents or medical records, where the model is trained on domain-specific data. The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF). ChatGPT is powered by a large language model made up of neural networks trained on a massive amount of information from the internet, including Wikipedia articles and research papers. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers.

Amazing app

Stanford researchers reported that GPT-4 «passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.» The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.

GPT-4o

Some, including Nature and JAMA Network, «require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author». As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.

• These limitations may be revealed when ChatGPT responds to prompts including descriptors of people.

• In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists.

{

• There’s even a Projects feature that keeps all your chats organized, plus a Library to manage all your generated images.

• This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.

• So far, users can make single-item purchases from domestic sellers on online marketplace Etsy, as well as some merchants on Shopify’s e-commerce platform.

Release of Instant Checkout Feature (September

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. Despite this, users may «jailbreak» ChatGPT with prompt engineering techniques to bypass these restrictions. […] It’s also a way to understand the «hallucinations», or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.

GPT-4 General Availability (July

|}
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. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. In one instance, Spinando casino ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users.
It is designed to generate human-like text and can carry out a wide variety of tasks. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts. I’ve covered the models and modes above, but here’s a reminder of all the core features (as of October 2025).
