How Many Questions Can You Ask ChatGPT

ChatGPT has become an inseparable tool for most people who work with a computer right now. Even the free tier, ChatGPT 3.5 is extremely powerful and able to do things that even experts thought we needed years and years to reach. All these goodies for free are causing users to wonder if there are limits to the app… so how many questions can you ask ChatGPT? Answering this will be the aim of this article, and we will cover the topic from all angles, whether you’re using the free version, the premium ChatGPT Plus, or working with the OpenAI API.

Quick overview… What is ChatGPT?

For those of you who are new this, firstly, where have you been? Secondly, let me give you a brief intro to ChatGPT. This is an AI (artificial intelligence) that is trained using vast amounts of written text from all over the internet, which can converse like a real person. Not only that, but it can answer academic questions, write code and even do your homework for you. So much so that one of the popular questions students wonder right now is whether teachers can tell when you use ChatGPT (click the link to find out more from an article I wrote recently). Naturally, using a powerful system like this makes people realize the cost behind operating it, and makes you wonder how many questions you can ask ChatGPT before it limits you?

How Many Questions Can You Ask ChatGPT (Free version)

The free version of ChatGPT has no limits on the questions you can ask it. The only limit would be your physical limit of how many questions you can get an answer to for the timeframe you’re communicating with the Chatbot. Basically ask away, you have as many questions as you like.

How Many Questions Can You Ask ChatGPT Plus (Premium version)

ChatGPT Plus, also known as GPT 4 is the paid version of the online chatbot. Currently the price is 20$ a month to be able to access it. Weirdly enough, it has a limit – you can ask it up to 25 questions every 3 hours.

Why limit the premium version while the free version has no limits?

This is a fair question, and the answer is many fold. Firstly, although you do not have a specific question limit with the free version, you get a slower service, and may get errors at times of demand. The paid ChatGPT account allows you to use GPT 3.5 (the chatbot available with the free version) with increased resources, and you get faster answers. It also has no limit on the number of questions. ChatGPT 4 on the other hand is the premium bot, and is much more powerful – it has better reasoning capabilities that GPT 3.5, but it comes with a caveat – it is also more resource intensive. While GPT 3.5 has 175 billion parameters, it was leaked recently that GPT-4 might be over 10 times the size of GPT 3.5. It is rumored that it has 1.8 trillion parameters, and is a mixture of 16 experts within the model – each about approx. 111 billion params. All this adds up to the need to limit the usage of the bot, at least through the chat.

How Many Questions Can You Ask ChatGPT Through Their API?

If you’re a developer, you might be interested in this section. If you are a regular user, at some point you might need to dabble with the API of OpenAI, as it gives you more freedom and options. Here, it largely depends on the model you are working with and the type of user level you are. There are 2 parameters to note: RPM – requests per minute, and TPM  – tokens per minute.

  • Free trial users can send 3 RPM and 40,000 TPM.
  • Paying users can send up to 60RPM and 60,000 TPM for the first two days.
  • After the first two days, paying users can send up to 3,500 RPM and 90,000TPM.
