ChatGPT vs Bing Chat: What's the difference and which one to use?

Which AI chatbot should you use? We pit two of the best options in this head-to-head comparison
September 15, 2023

Natural language chatbots like ChatGPT and Bing Chat have become the latest focal point of the tech industry. You’ve probably already heard about how these chatbots can write essays, poems, and even computer code. Beyond that, these tools can also simplify complex topics and summarize entire novels. But even though both look similar on the surface, the quality of responses actually differs depending on which service you use. So in this article, let’s take a look at the differences separating ChatGPT vs Bing Chat and which one you should use.


If you’re in a hurry, here’s a quick summary of how ChatGPT differs vs Bing Chat:

  • Both ChatGPT and Bing Chat rely on a large language model known as GPT. However, Microsoft uses a more advanced model for Bing Chat, which gives it the upper hand.
  • Bing Chat is available on more platforms than ChatGPT.
  • Using Bing Image Creator, you can generate images in addition to text.
  • Since Bing is a search engine, its Chat feature can access web results and up-to-date information. ChatGPT, meanwhile, does not have knowledge of recent events.
  • You can optionally subscribe to ChatGPT Plus for priority access and other benefits over the free tier.
  • Bing is free to use, but Microsoft relies on ad revenue so you may see sponsored results from time to time.
  • Bing offers three Chat modes, while ChatGPT does not have any settings or fine-tuning options.
  • ChatGPT may offer longer creative responses. However, this may come at the expense of accuracy as it cannot fact-check its responses with external sources.
  • Bing Chat officially supports many non-English languages. While ChatGPT can understand several languages too, most of its training involved English words and samples.

What can you do with Bing Chat and ChatGPT?

ChatGPT and Bing Chat fall under the category of generative AI, which means they have the ability to generate brand-new text that has never been written before. Naturally, this kind of AI is only useful if it can provide accurate information, so how does it work?

In a nutshell, both rely on a large language model developed by San Francisco-based startup OpenAI. ChatGPT’s underlying model, named GPT-3.5, has been trained on billions of text samples gathered from across the internet. However, Bing Chat uses the more advanced GPT-4 language model. You can also access GPT-4 via ChatGPT Plus, but you’ll have to pay for that privilege.

At the end of the day, both chatbots generate text that reads like it was written by a human. We’ll go through some examples in the next section.

Both ChatGPT and Bing Chat can generate human-like text on a variety of topics.

Bing also goes one step further as it can search the internet for information in real-time. Admittedly, this is a double-edged sword since any misinformation it stumbles upon can introduce bias into the response. However, in most cases, Bing Chat also cites its sources at the bottom of each response. This allows you to easily verify the output’s accuracy by simply clicking on one of the citations.

On that note, it’s important to not completely trust either chatbot as both ChatGPT and Bing Chat are susceptible to “hallucinating”. That’s when a chatbot makes up a response that sounds convincing but has no basis in reality.

ChatGPT vs Bing Chat: Accuracy and knowledge

If you’re looking for information on a technical subject or recent event, Bing Chat will almost always deliver a higher-quality response as it can search the internet. But if you’re simply after historical knowledge, ChatGPT will do reasonably as well since it has some knowledge of events prior to 2021.

For example, you can use Bing while shopping to compare the pros and cons of newly-released products or to prepare a personalized itinerary for your next vacation. Both of these tasks require a fair amount of web-based research, which will take you far longer to do manually.

On the other hand, ChatGPT fares better when it comes to creative prompts as it’s tailored for conversation. While you could ask Bing Chat to write a poem, story, or essay, you’ll find that it’s extremely fact-driven and that may come at the expense of creativity.

That said, Bing does let you choose from three modes, namely Creative, Balanced, and Precise. The Creative mode comes the closest to ChatGPT’s default behavior, as you can see in the screenshot above. Even so, our testing found that ChatGPT provides longer responses.

Finally, Bing is one of the best free AI image generators currently available. Simply enter a text prompt as pictured above and it will generate a few choices to choose from. OpenAI does offer DALL-E for the same purpose but it’s not integrated within ChatGPT at the moment.

ChatGPT vs Bing: How and where to use them?

ChatGPT launched in late 2022 as a website-based chatbot. That open access continues to this day but that may change once OpenAI gathers enough data and the project exits the research preview phase.

Microsoft has followed the same free-to-use strategy with Bing Chat. The only condition is that you’ll need to use Microsoft’s Edge web browser to access the chatbot.

You can use both ChatGPT and Bing Chat for free.

You can also use Bing Chat on many more platforms. Microsoft has brought its chatbot to the Bing mobile app, Swiftkey keyboard, and Skype group chats. Bing Chat even rivals Google’s Bard chatbot in terms of availability and versatility. That said, ChatGPT has started to catch up too in this area with an official app now available for Android and iOS smartphones.

ChatGPT vs Bing: Limitations and pricing

OpenAI imposes very few restrictions on ChatGPT’s usage, even if you don’t pay for it. You may run into some errors if you send off too many messages within a few minutes, but that’s meant to combat abuse. You can also have relatively longer conversations with the chatbot — no per-conversation limits to speak of.

That said, you have the option of paying for a $20 monthly ChatGPT Plus subscription. Doing so grants you a few benefits: priority access to the service, faster response times, and early access to new features. Paid accounts also get higher-quality responses, thanks to a new GPT-4 mode that should perform about as well as Bing Chat.

Unlike Bing, ChatGPT doesn't have per-conversation limits.

Meanwhile, Bing can understand most major languages including French, German, and Japanese. However, it does have a few other limitations. For one, you can only have 300 conversations with it in a single day. But more importantly, each thread is limited to 30 replies, so long back-and-forth conversations may not always be possible. Having said that, it’s worth noting that Microsoft has reduced these restrictions over time. The company also says that most people find what they’re looking for within five replies or fewer.

ChatGPT will also respond in other languages, but the underlying GPT-3.5 model was primarily trained on English samples and text. Approximately 92% of ChatGPT’s training data involved English. Responses in other languages will also use up more tokens and you will run into ChatGPT’s character limit sooner.

With Bing Chat, you cannot pay for higher limits or better responses because it’s funded by advertising instead. According to a Microsoft announcement post, you may see ads show up embedded inside chat responses. For example, asking for clothing recommendations may result in Bing showing you suggestions from local retailers. Likewise, publishers can pay Microsoft to appear in relevant responses, as pictured below.

What about ChatGPT Plus vs. Bing Chat?

I’ve spoken at length about ChatGPT’s free version so far, but what if you opt to pay for the Plus tier? That changes things quite a bit. The $20 per month subscription opens up access to the more advanced GPT-4 language model in ChatGPT.

In my time using Bing Chat, I found that its responses almost always fared better than the free version of ChatGPT. The difference is particularly noticeable in areas like logical reasoning and creative tasks like essay writing or programming.

So why should you pay for ChatGPT Plus vs just using Bing Chat for free? If you value ChatGPT’s creative and wordy output but want higher-quality responses, it might be worth the $20 per month. After all, it’s a small price to pay if the chatbot helps make your life easier.

Moreover, the subscription also unlocks access to ChatGPT plugins, which enable the chatbot to perform many more tasks. For example, the Wolfram plugin allows the chatbot to solve complex math problems and answer scientific questions more truthfully.
