What’s the Difference Between ChatGPT 3.5, 4, and 4.0?


What's the Difference Between ChatGPT 3.5, 4, and 4.0

Some people love while others hate ChatGPT. Some use it every day at work and university to expedite their tasks, while others are weary of its low-quality and plagiarized content. Will this issue ever be resolved? Read our article to discover the distinctions between the various versions of ChatGPT.

What Chat GPT Is?

The first public version – Chat GPT 3.5

GPT-3.5 made its debut in March 2022, representing a significant advancement over the GPT-3 architecture. With enhancements in scale and training data, it stands as the latest version available for free use within the OpenAI ChatGPT service, albeit without internet search capabilities.

This version boasts improvements in natural language understanding and generation. In comparison to its predecessor, GPT-3.5 exhibits superior coherence, relevance, and contextual comprehension. It excels in processing more intricate instructions with greater accuracy.

Furthermore, there’s the lesser-known GPT-3.5 Turbo, which brought forth several enhancements beyond the original release. Positioned as a precursor to GPT-4, this version of the language model offers developers the flexibility to tailor the model to various applications and deploy them at scale.

Chat GPT 4

In March 2023, GPT-4 made its debut, marking a significant leap forward in AI capability. Distinguished by its capacity to analyze both text and images, GPT-4 unlocks a realm of possibilities for comprehending and generating content enriched with visuals.

Compared to the earlier version, GPT-3.5, this version understands context better, handles complex reasoning more effectively, gives more accurate responses, and creates text that sounds more human.

Moreover, GPT-4 offers increased flexibility for fine-tuning and customization tailored to specific applications.

However, one drawback lies in its heightened demand for computational resources, translating into elevated maintenance costs for the company.

It’s important to note that while GPT-4 can process images, its functionality centers on utilizing images as input. OpenAI also incorporates the DALL-E model, dedicated to generating AI-generated images based on textual prompts.

GPT-4 Turbo

In November 2023, GPT-4 Turbo was introduced. This version of GPT-4 includes subtle improvements. It performs just as well as the original GPT-4 but requires less computer power, which helps lower the costs of running it.

Among its enhancements are expedited response times, rendering it suitable for applications necessitating swift interactions, and optimized resource utilization, enhancing accessibility across diverse applications.

Despite its balanced performance and cost-effectiveness akin to GPT-4, some compromises may slightly impact accuracy in specific tasks.

Presently, access to GPT-4 and Turbo is exclusively available through a paid subscription.


Meet GPT-4o, the latest marvel from OpenAI, unveiled in May 2024. Unlike its numerical predecessors, this isn’t GPT-4.0, but rather GPT-4 “o,” signifying its “omni” capabilities.

Harnessing the GPT-4 architecture, this iteration transcends text-based interactions, now seamlessly processing text, audio, imagery, and video inputs. OpenAI boasts it to be the pinnacle of human-like interaction, with audio processing nearing human response times in conversation. Its text and code reasoning prowess matches that of “Turbo,” ensuring swift and cost-effective translations in the API.

GPT-4o sets itself apart with unparalleled proficiency in comprehending video and audio, even possessing memory of objects and events—a feat unprecedented in OpenAI’s lineup.

Embraced as the new standard for ChatGPT, GPT-4o does come with caveats. While it’s the default, there’s a limit on daily prompts. Once exceeded, ChatGPT reverts to GPT-3.5.

A noteworthy addition to the free tier is its ability to conduct online searches via Bing, a privilege previously reserved for paid GPT-4 subscribers. Once the daily limit is hit and you’re back to GPT-3.5, online searches become inaccessible.

Should you desire unrestricted access, OpenAI offers a $20 monthly subscription to lift the constraints.

Data Privacy & Ethics in Artificial Intelligence

On March 13, 2024, the European Parliament formally adopted the EU Artificial Intelligence Act (“AI Act”) with a large majority of 523-46 votes in favor of the legislation. The AI Act is the world’s first horizontal and standalone law governing AI, marking a significant legislative milestone for the EU. The proposed rules are:

  • Addressing risks specifically created by AI applications.
  • Prohibiting AI practices that pose unacceptable risks.
  • Determining a list of high-risk applications.
  • Setting clear requirements for AI systems used in high-risk applications.
  • Defining specific obligations for deployers and providers of high-risk AI applications.
  • Requiring a conformity assessment before a given AI system is put into service or placed on the market.
  • Implementing enforcement measures after a given AI system is placed on the market.
  • Establishing a governance structure at both European and national levels.

As ChatGPT and other AI tools keep getting better, it’s important to balance innovation with user trust and following the rules. Whether you use ChatGPT every day or are just keeping an eye on it, knowing about these changes is key to staying up-to-date with AI.
