Which ChatGPT version is best, who created it, and why it keeps freezing

The best ChatGPT version for most people is the default model ChatGPT picks for you, with a reasoning or thinking mode for hard problems; the specific model names change every few months. ChatGPT was created by OpenAI, launched in November 2022, and built by pre-training a GPT model on large amounts of text and then training it to follow instructions with human feedback. This page also explains ChatGPT Enterprise, what you get without paying, practical uses, and how to fix ChatGPT freezing in Chrome or on a Mac, and Cursor freezing too.

Which ChatGPT version is best?

For everyday tasks, the default model in ChatGPT is the best balance of speed and quality. For hard maths, complex code, data analysis or careful planning, use the reasoning or thinking option, which takes longer but makes fewer mistakes.

OpenAI now routes many requests automatically, sending simple questions to fast models and hard ones to reasoning models, so manual model picking matters less than it did. Rules of thumb: use a fast mode for rewriting, summarising and quick facts; use thinking for anything with several steps where a wrong step is costly; use deep research when you need a cited report from many sources. Model names and availability per plan change often, so check the model picker in your account rather than lists online.

Who is the founder of ChatGPT?

ChatGPT was created by OpenAI, the AI research company founded in December 2015 by a group that included Sam Altman, Greg Brockman, Ilya Sutskever, Wojciech Zaremba, John Schulman and Elon Musk. Sam Altman is OpenAI's chief executive.

No single person invented ChatGPT; it was built by OpenAI's research and engineering teams on years of earlier work, including the transformer architecture published by Google researchers in 2017 and OpenAI's own GPT models from 2018 onwards. Elon Musk left OpenAI's board in 2018. Microsoft became OpenAI's major partner and investor, which is why Microsoft's Copilot products use OpenAI models.

How was ChatGPT created?

ChatGPT was created in two broad stages: pre-training a large GPT language model on a huge body of text to predict the next word, then fine-tuning it to follow instructions and hold conversations, using examples written by people and reinforcement learning from human feedback.

In the feedback stage, human reviewers ranked several model answers to the same prompt; a reward model learned those preferences, and the language model was trained to produce answers the reward model scored highly. OpenAI described this method in its 2022 paper on InstructGPT, ChatGPT's predecessor. ChatGPT launched as a research preview on 30 November 2022 and reached a very large user base within weeks. Since then OpenAI has added newer models, reasoning modes, tools such as search and code execution, voice, images and memory.

What is ChatGPT Enterprise?

ChatGPT Enterprise is OpenAI's plan for large organisations. It adds enterprise security and admin controls, single sign-on, data that is not used to train OpenAI's models by default, higher limits, and connectors to company tools.

Organisations choose it so employees can use ChatGPT on work data without the risks of personal accounts: admins manage users, set which features and connectors are allowed, and see usage analytics, while compliance features help meet company policies. Smaller teams use the business plan with similar protections. For students, the relevant point is that the ChatGPT you use at an internship may have different features and rules from your personal account, so read the company's AI policy before pasting anything into it.

How does ChatGPT treat you without premium?

Free users get the same core ChatGPT with capable models, but with lower limits. When you hit a limit, ChatGPT falls back to a lighter model or asks you to wait, and some advanced features are limited or unavailable.

On the free tier you can chat, search the web, upload files and images, use voice and create images within limits. What you notice is rationing: the strongest model and features such as deep research run out sooner, and responses may slow at peak times. Quality on simple tasks is very similar. Make the free tier go further with one clear, complete prompt instead of many follow-ups, new chats per task, and the fast model for simple work.

What are some examples of using ChatGPT?

People use ChatGPT to explain concepts, write and edit text, write and debug code, analyse data and documents, plan projects, practise interviews and languages, and brainstorm ideas.

Examples that work well for students and developers:

• "Explain recursion with a real-life analogy, then give me three practice problems."
• "Here is my error and the code around it. What is wrong and how do I fix it?"
• "Turn these lecture notes into a one-page summary and ten quiz questions."
• "Review my resume against this job description and list the gaps."
• "Act as an interviewer for a junior Python developer role and grade my answers."
• "Analyse this CSV and plot monthly totals."

Check facts and run code before relying on it.

Why does ChatGPT keep freezing?

ChatGPT usually freezes because the conversation is very long, the browser is short of memory, an extension interferes with the page, or OpenAI's service is having problems. Starting a new chat fixes most cases.

Work through these:

• Check OpenAI's status page for incidents.
• Start a new chat and paste a short summary of the old one.
• Close other heavy tabs and apps.
• Try a private window to rule out extensions.
• Update the browser or use the desktop app.
• Switch networks or turn off a VPN.

If freezing happens only in one chat with lots of code blocks or images, that chat has simply become too heavy for the page to render smoothly.

Why does ChatGPT keep freezing on Chrome?

On Chrome, freezing usually comes from a very long chat, an extension such as an ad blocker or grammar checker modifying the page, too many open tabs using memory, or a corrupted site cache.

Fixes for Chrome:

• Open ChatGPT in an Incognito window; if it works, disable extensions one by one.
• Clear cookies and cached data for chatgpt.com from site settings.
• Update Chrome and restart it.
• Check that hardware acceleration is on in Chrome's system settings.
• Use Chrome's task manager to see whether the ChatGPT tab uses unusual memory.

If none of this helps, compare with another browser or the desktop app to see whether the problem is Chrome-specific.

Why does ChatGPT keep freezing on my Mac?

On a Mac, freezing usually comes from a very long conversation, low memory with many apps open, an outdated browser or ChatGPT app, or a browser extension. The same fixes apply: new chat, fewer apps, updates, no extensions.

Specific steps:

• Update the ChatGPT Mac app, or your browser, and macOS.
• Open Activity Monitor and check memory pressure; quit heavy apps if it is high.
• If the desktop app freezes, quit it fully and reopen it, or sign out and back in.
• Try ChatGPT in Safari or Chrome to see whether the problem is the app or your account.
• Start a new chat for long-running work.

Older Macs with limited memory struggle with very long chats full of code, so keeping conversations short helps most.

Why does Cursor AI keep freezing?

Cursor usually freezes while indexing a very large project, when heavy extensions run alongside it, when memory is short, or when the editor is out of date. Excluding big folders from indexing fixes most cases.

Steps that help:

• Add a .cursorignore file listing folders such as node_modules, build outputs, datasets and logs, so Cursor does not index them.
• Update Cursor to the latest version.
• Disable extensions one at a time to find a misbehaving one.
• Close projects you are not using and check memory use.
• Open the developer tools or logs from the Help menu to see the actual error.

If one long agent session hangs, stop it, start a new chat and give a smaller task.
