ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history. In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. Shortly after the bug was fixed, users could not see their conversation history. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. In March 2023, a bug allowed some users to see the titles of other users’ conversations. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions.
Of all of the punctuation marks we use, the comma is especially versatile and has many different possible uses, sometimes within one sentence. Proper punctuation is important in writing as it makes our sentences clear and easier to read. If the items in the list are longer and more complicated, you should always place a final comma before the conjunction. Put commas between items in a list. If you do not have two subjects and two verbs separated by the FANBOYS, you do not need to insert the comma before the FANBOYS.
Though the AP Stylebook is a notable exception, most American style guides recommend using the serial comma for the sake of clarity and consistency. If the introductory element doesn’t require a pause, you can usually omit the comma. You can tell whether adjectives are coordinate by inserting the conjunction and between them. The comma is the most common mark of punctuation—and the most commonly misused. Commas are used to set off direct quotations from the rest of the sentence.
Even though ChatGPT can handle numerous users at a time, it reaches maximum capacity occasionally when there is an overload. The model’s output can also track and profile individuals by collecting information from a prompt and associating this information with the user’s phone number and email. If the data the model pulls from has any bias, it is reflected in the model’s output. ChatGPT can also be used to impersonate a person by training it to copy someone’s writing and language style. Businesses and users are still exploring the benefits of ChatGPT as the program continues to evolve.
ChatGPT Team Release (January
There are a few places in a sentence where a comma should (almost) never appear. When addressing another person by name, set off the name with commas. If you are writing for a British audience, put the comma after the closing quotation mark.
The comma is a valuable, useful punctuation device because it separates the structural elements of sentences into manageable segments. Typically, commas are unnecessary with correlative conjunctions. In these cases, the writer is using commas to let the reader know where in a sentence emphasis and pauses should fall.
What Are Commas (,) And How Do You Use Them?
According to research conducted by OpenAI and AI safety organization Apollo Research, o1 provides more intelligent answers than GPT-4o while also attempting to deceive users more than any major AI model available. This update allows users to interact with ChatGPT via speech, and to upload images that the model can analyze and use to generate outputs. This update allows users to create customized GPTs that follow specific instructions and knowledge provided by the builder.
- This agreement gives ChatGPT more current information in its chatbot answers and gives users another way to access news stories.
- Although using commas correctly may seem mysterious, it can be easy if you follow a few guidelines.
- With users’ permission, these apps will be able to access their financial data and offer personalized financial insights and recommendations, as well as review credit cards, personal loans and mortgages.
- In order to sift through terabytes of internet data and transform that into a text response, ChatGPT uses a technique called transformer architecture (hence the “T” in its name).
- When an explanation or definition occurs as an appositive, it should be set off with commas.
Mobile apps
To keep training the chatbot, users can upvote or downvote its response by clicking on thumbs-up or thumbs-down icons beside the answer. ChatGPT currently provides access to GPT-3.5 and limited access to the GPT-4o language model. ChatGPT is trained with reinforcement learning through human feedback and reward models that rank the best responses. GPT-4o Mini, the fastest model, is optimized for everyday tasks and available to all users (free-tier users are automatically switched to it when hitting use limits on GPT-4o).
Comma Rules and Usage With Examples
They argue that whatever is inside a pair of commas should be capable of being removed without turning the sentence into nonsense. With this approach, the commas reflect the natural pausing points if the sentence were to be read aloud. There is a comma before the vegas casino app conjunction (but), and the nonessential comment (in the end) is set off with a pair of commas. A dependent clause, unlike an independent clause, cannot stand on its own as a complete sentence.
- After lists, the most important function of the comma is to set off nonrestrictive or nonessential information.
- When assembling training data, the sourcing of copyrighted works may infringe on the copyright holder’s exclusive right to control reproduction, unless covered by exceptions in relevant copyright laws.
- Apple’s four new iPhones feature more differences between the latest models than ever before, so which one should you buy?
- Commas are not used with essential expressions because they provide necessary information in a sentence.
- ChatGPT shows inconsistent responses, lack of specificity, lack of control over patient data, and a limited ability to take additional context (such as regional variations) into consideration.

Jaffri emphasized that malicious or careless deployment, not the models themselves, is the root of most risks. For heavy users, ChatGPT Pro is available for $200 a month with the highest limits and capabilities. Models o3 and o4-mini are reasoning models, where o3 is especially strong in coding, math and visual tasks, while o4-mini is a lighter and cost-efficient version. All ChatGPT users on the web and iOS/Android now have a Library where images are automatically saved, letting you revisit, reuse or edit them without digging through old chats.

For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5. And several authors and journalists have sued OpenAI for copyright infringement, claiming their work was scraped from the internet and used as training data without their permission. Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it. ChatGPT’s impressive writing abilities have not gone without some controversy. But then the value of domain experts will continue to refine that and make it better than whatever a model can produce.”
GPT-4.5
Marketplace for millions of educator-created resources Compound subjects and predicates are often connected by conjunctions such as and or or. In general, a nonrestrictive modifier is one that can be removed without changing the meaning or clarity of a sentence. In short, coordinate adjectives can have their order switched around without changing the meaning of the sentence. Depending on which style guide you use, the Oxford comma might be considered optional.
GPT-5.2 Thinking is meant for more complex tasks, like summarizing long documents, coding, answering questions about uploaded files, and planning decisions. OpenAI says that GPT-5.2 outperforms industry professionals at knowledge work tasks spanning 44 occupations, with the model scoring 70.9 percent on the GDPval test. The new model offers improved general intelligence, long-context understanding, agentic tool-calling, and vision, so it is ideal for real-world, professional use. It’s better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long context, using tools, and completing multi-step projects. GPT-5.2 is OpenAI’s “most capable model series yet for professional knowledge work.” OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly.
Without commas, sentences would jumble words together and create confusion surrounding the importance of specific information. A comma can be used to join two or more independent clauses together. Two commas can be used to set off additional information that appears within the sentence but is separate from the primary subject and verb of the sentence.
The model has been trained through a combination of automated learning and human feedback to generate text that closely matches what you’d expect to see in text written by a human. Custom instructions allow users to save directions that apply to all interactions, rather than adding them to every request. The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users.
The listing comma
As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use. This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. In the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used. 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. A shadow market has emerged for Chinese users to get access to foreign software tools.
Unlike other chatbots, ChatGPT can remember various questions to continue the conversation in a more fluid manner. ChatGPT was trained with online text to learn the human language, and then it used transcripts to learn the basics of conversations. The transformer predicts text — including the next word, sentence or paragraph — based on its training data’s typical sequence.
ChatGPT uses deep learning, a subset of machine learning, to produce humanlike text through transformer neural networks. The transformer pulls from a significant amount of data to formulate a response. ChatGPT works through its Generative Pre-trained Transformer, which uses specialized algorithms to find patterns within data sequences. OpenAI — an artificial intelligence research company — created ChatGPT and launched the tool in November 2022.
