ChatGPT-3 and ChatGPT-4

ChatGPT-3 is a natural language processing tool that creates text with minimal human input. It’s capable of content generation, summarisation and translation, relying on the Internet for information. However, it’s had serious challenges, like not handling complex requests and providing inaccurate information.

ChatGPT-4 can understand more complex queries, has more advanced reasoning abilities and is more factually accurate. It outperforms its predecessor on machine learning benchmarks and has better multilingual capacity. It’s also roughly eight times faster than version 3.


  • Substantial time savings.
  • Cost-effective and scalable.
  • Generates readable content with human help.


  • Entirely dependent on the Internet, compromising veracity.
  • Needs much human prompting for complex tasks.
  • Cannot empathise with readers’ feelings.

Our experience

ChatGPT is extremely good at quickly doing research and generating a workable first draft. However, without a human to infuse the content with flair and empathy, it’s often generic and somewhat sterile.
