GPT-4 is the model underlying ChatGPT Enterprise and ChatGPT Teams, which are the first formal commercial enterprise solutions by Open AI. GPT-4 claims the limelight for its additional features, such as multimodality and considerations for API implementation. 

Differences between GPT-4 and GPT-3.5

The selection of a generative AI model can be difficult without comparing the respective features. You can break down the differences between the two models in a GPT 4 vs. 3.5 comparison based on different aspects such as features, capabilities, and other parameters. Here is an overview of the major differences between GPT 3.5 and GPT 4 that you should watch out for at all costs.

• Extended Capabilities 

The first thing you need to check in the GPT 4 and 3.5 difference points at the comparison between the extended capabilities of the two models. OpenAI introduces new features in its GPT models to meet the requirements of complex use cases in different industries.

GPT 3.5 presents a wide range of capabilities, such as understanding and generating text in natural language for addressing different natural-language-related tasks. It can help in translation of text into different languages with accuracy and fluency. GPT-3.5 can also generate concise summaries or answer questions by offering relevant information. It is also a useful resource for generating content for different use cases, such as code generation or writing emails. 

GPT-4, on the other hand, has been designed to offer better functionalities than its predecessor. OpenAI has created GPT-4 to offer better reliability and creativity alongside the capabilities for managing nuanced instructions more effectively. Most of the responses to “What is the difference between GPT-3.5 and GPT-4?” focus on the capabilities introduced in GPT-4.

The foremost extended functionality in GPT-4 is the assurance of multimodality, which enables the acceptance of images as inputs for analysis and the generation of inputs. GPT-4 also stands out with its two context window sizes featuring 8,192 and 32,768 tokens, which help the model manage more than 25,000 words of text. It can help address use cases such as extended conversations, document search and analysis, and long-form content creation.

Another significantly extended functionality you can find with GPT-4 includes better safety and alignment features. OpenAI has implemented necessary measures to ensure that GPT-4 is more secure and better aligned with user intent. The internal assessments by OpenAI in April 2023 have revealed that GPT-4 is 82% less likely to respond to requests for problematic content. On top of it, GPT-4 is 40% more likely to generate contextually relevant answers than GPT-3.5. You must also note that GPT-4 API also features the Chat Completions API, which supports text summarization and completion of programming code.
