Each year artificial intelligence continues to evolve, constantly bringing with it new technologies, features, and ways to cut down your workload.

The big name in AI is ChatGPT, and their latest model, GPT 4, is part of a subscription service known as ChatGPT Plus. But is it worth it, and what exactly are you paying for with ChatGPT Plus?

What is ChatGPT Plus?

ChatGPT Plus is a subscription plan offered by OpenAI that provides users with several benefits over the free tier:

  1. Access to GPT-4: Subscribers get to use the latest and most powerful version of ChatGPT, GPT-4. This model is known for its enhanced capabilities in terms of understanding and generating human-like text. More on that below.
  2. Reduced Downtime: Users experience less downtime, especially during peak times when the service might be overloaded.
  3. Faster Response Times: Subscribers benefit from quicker responses, making the interaction more seamless and efficient.
  4. Priority Access to New Features: Subscribers get early or exclusive access to new features and improvements.

While at first glance ChatGPT 3.5 and ChatGPT 4 might seem much of the same thing, there are a fair few differences that might make the subscription model worth the investment for some people.

Architecture and capacity

ChatGPT 3.5, based on the GPT-3 architecture, was already an impressive AI model with its ability to understand and generate human-like text.

ChatGPT 4 however, has made incredible strides in improving the model, increasing the parameters from millions into the billions, which enhances the AI model’s understanding of your prompts, as well as offering much higher quality output.

Context Handling

One of the biggest and most notable improvements in ChatGPT 4 is its ability to handle longer and more complex content.

While ChatGPT 3.5 could manage a decent amount of context, its successor can maintain context over much longer conversations, leading to more accurate, and often more coherent and contextually appropriate responses.

For example, imagine you’re telling a long story to a friend. With ChatGPT 3.5, your friend might sometimes forget earlier parts of the story or mix up details. But with ChatGPT 4, it’s like your friend has a super memory and can keep track of everything you say.

Training and Data

ChatGPT 4 features an updated training regime and a broader dataset that spans more topics and includes more recent information.

Thanks to this, ChatGPT 4 is capable of offering more accurate information based on a wider range of subjects when compared to ChatGPT 3.5.

ChatGPT-4 and ChatGPT-3.5, including their newer Turbo versions, have training data up until April 2023. This enables them to process prompts based on information available up to that date.

However, if you’re conducting product research on items released after April 2023, these models may lack the most recent information.


If you’re a developer looking for AI assistance with coding, ChatGPT 4 might be the solution for you.

ChatGPT 4 performs better in specialized tasks such as coding, complex problem-solving, and in-depth analysis. This is largely due to the improved training, larger model size, and updated training techniques.

ChatGPT Plus comes with some big upgrades over ChatGPT 3.5, but whether you need it really boils down to how you’ll be using the model.

If you just need help here and there with sentence structure, ChatGPT 3.5 will do the trick.

On the other hand, if you’re a heavy user or need to tackle more complex tasks, then ChatGPT Plus might be the better choice for you.

ChatGPT Plus subscribers have access to the latest updates and features, generally before they are rolled out to the public, ensuring that they always get the best features possible.

Increased session lengths

ChatGPT Plus offers longer interaction sessions, which is particularly beneficial when engaging in complex tasks or tasks that require more extensive dialogue.
