Similarities Between ChatGPT 3.5 Vs. GPT 4

As mentioned by the creators, GPT-4 is a significant upgrade to the ChatGPT-3.5 model, but did you know they share more similarities than differences?

Although an upgrade to the older model, GPT-4 shares many similarities to its predecessor in terms of data training, functions, responses, and features.

You will likely find some similarities between ChatGPT-3.5 and GPT-4.

1. Transformer Architecture

Both ChatGPT-3.5 and GPT-4 are built on the transformer architecture, a deep learning architecture introduced in 2017.

The transformer network in GPT models consists of a series of layers, each of which uses self-attention mechanisms to determine which parts of the input sequence to focus on.

When you ask a question, the transformer network uses self-attention mechanisms to encode the input sequence and generate a hidden representation of the message or tokens.

It generates a response based on the token, generating words one at a time based on the patterns it has learned from the training data.

When you converse with any of these models, they will generate the most natural-sounding text.

2. Similar Training Model

ChatGPT-3.5 and GPT-4 are trained on similar deep learning techniques, which departs from the previous GPT-2 and GPT-3 models.

Besides, they are trained on publicly available data, licensed third-party data, and fine-tuned using RLHF (Reinforcement Learning from Human Feedback).

Although not publicly claimed, both GPT models utilize Recurrent Neural Networks (RNNs), commonly used in natural language processing.

After all, they process variable-length input data sequences by applying the same weights to each sequence element.

3. Capabilities And Performance

GPT-4 and GPT-3.5 are alike regarding sharing capabilities and performances.

Like its predecessor, GPT-4 can strike a similar conversational style with the user.

They both are likely to provide the same answer to a question in a similar format but may slightly change when the complexity of the task reaches a sufficient threshold.

For example, GPT-4 can receive image inputs and provide an appropriate answer, while GPT-3 or GPT 3.5 cannot process images altogether.

Regarding performance, the latest GPT models are alike as they avoid responding to requests for disallowed content and toxic content generation.

4. Practical Applications

Despite the upgrade in the model, training data, and response time, both GPTs serve the single purpose -responding to users’ queries.

Therefore, they both share similar applications, such as:

  • Language Generation: They generate high-quality, coherent, and contextually appropriate sentences.
  • Translation: Both GPT models can translate text from one language to another with impressive accuracy and fluency.
  • Question Answering: They are trained to answer questions, from factual questions to more complex reasoning tasks.
  • Text Completion: They complete sentences and paragraphs based on the context provided, including completing incomplete articles, texts, programming functions, etc.
