GPT-4 is available and can be used by all registered ChatGPT-Plus users. GPT-4 was publicly presented on a YouTube livestream from OpenAI on March 14, 2023. Even earlier, at the beginning of March, the rumor mill was brewing after large language models were presented as a disruptive force for companies at the Microsoft event “AI in Focus — Digital Kickoff” — and Andreas Braun mentioned in a subordinate clause that the immediate release of GPT-4 was imminent:
“We will be presenting GPT-4 next week, where we have multimodal models that will offer completely different options — videos, for example.”
- Dr. Andreas Braun, CTO Microsoft Germany
In particular Following the announcement, there was a lot of discussion on LinkedIn and Twitter about the new features GPT-4 brings. The Microsoft CTO's statement suggested that GPT-4 would offer new options specifically for creating video and audio formats.
The previous versions GPT-3 and GPT-3.5 already impress with their eloquence, quick reactions and the wide range of applications. The new options GPT-4 offers are explained below:
What Can GPT-4 Do?
According to OpenAI, GPT-4 generally has the following capabilities:
The GPT-4 can solve difficult problems with greater accuracy thanks to its wider general knowledge and problem-solving capabilities.
OpenAI also addresses the following three core areas in more detail: “Creativity”, “Visual Inputs” & “Longer Context”
Creativity
- “GPT-4 is more creative and collaborative than ever before. It can work with users to create, edit, and review creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user's writing style. ”
Visual Inputs
- “GPT-4 can accept images as input and generate labels, classifications, and analyses.
Example: If you upload an image that shows flour, eggs, butter, and milk, GPT-4 is able to make suggestions about what you can do with these foods:
- Pancakes or waffles
- Crepes
- French toast
- omelet or frittata
- Quiche
- Custard or pudding
- Cakes or cupcakes
- Muffins or bread cookies or biscuits”
At present, GPT-4/ChatGPT does not yet allow you to upload images or documents yourself in order to have them evaluated. However, this may change in a timely manner.
Longer Context
- GPT-4 is able to process more than 25,000 words of text, enabling use cases such as creating long-form content, advanced conversations, and searching and analyzing documents.
More Abilities
- GPT-4 can identify humor:
During the initial presentation of GPT-4, an example of AI's understanding of humor was shown. It should be borne in mind that humor is very abstract and even among people it is often discussed what counts as humor and what does not. The fact that AI can identify humor — or take steps in that direction — is a major milestone. During the presentation by OpenAI, the sense of humor was presented using an example: GPT-4 was able to describe why a comic shown was considered funny.
- GPT-4 can check contracts and detect errors:
In this way, GPT-4 was able to immediately find weaknesses in an Ethereum contract within a few seconds.
- Create parts of program code:
Extending existing code to include requirements works very well: For example, changing and creating database queries
- Documenting program code:
Documenting program code adequately and well is sometimes a time-consuming task that can ideally be taken over by GPT-4 — as internal tests carried out by us have shown.
- Email templates create:
Generating email templates is not an unusual or new use case for using ChatGPT. But GPT-4 is not only good at designing classic emails, but is also developed to such an extent that it can have a certain “sensitivity.” Ideal for formulating email texts on difficult topics that aren't easy for you — or at least provide inspiration for them.
- New potentialities The visual Communication:
ChatGPT recently (December 2024) introduced real-time video, screen sharing, and image uploads in the mobile app — ideal for visual communication, presentations, or sharing complex content. These features are available to Team, Plus, and Pro users (except in the EU, Switzerland, Iceland, Norway, and Liechtenstein) and are subject to daily usage limits.
- Finding titles and titles (at moinAI)
We also use ChatGPT for internal purposes. For example, to find inspiration for suitable headlines and titles for new categories in our product moinAI. GPT-4 can even give good advice when it comes to choosing the right emoji.
When Was GPT-4 Officially Unveiled?
GPT-4 was presented for the first time on March 14, 2023 at 9 pm via a YouTube live format from OpenAI. The recording is here visible.
What Can GPT-4 not Do?
Similar to GPT-3 in conjunction with ChatGPT, there is the problem that artificial intelligence sometimes comes up with content and presents it as facts. At this point, too, it is important to always carry out a fact-check before trusting the information provided and disseminating it to others.
The wiki article “Wrong Answers From AI? This Is how AI Hallucinations Arise” offers more background information.
How can I Use GPT-4 for Free?
OpenAI has announced that GPT-4 will be completely removed from the ChatGPT interface at the end of April 2025 and replaced by the new model GPT-4o. For ChatGPT Plus users, this means that GPT-4 will no longer be available in the model selection starting April 30. However, it will continue to be available to developers and companies via the OpenAI API. For those using ChatGPT for free, however, nothing will change – GPT-4o (or the lower-performance variant GPT-4.1 mini) will be the default model.
What Does GPT Stand for?
GPT stands for “Generative Pre-trained Transformer” and refers to a family of large neural networks developed by OpenAI to handle natural language processing tasks such as word generation, translation, and text classification.
What Is GPT-3?
GPT-3 is a model in the GPT series and was released in 2020. It contains 175 billion parameters and was the largest and most powerful language model on the market before GPT-4 and GPT-4o. GPT-3 has achieved impressive results in many NLP tasks, such as translation, text completion and question-answer tasks, and is an important milestone in the development of artificial intelligence and natural language processing.
GPT-4 vs. GPT-3
According to OpenAI, GPT-4 is a significant increase over the previous model:
“We spent 6 months making GPT-4 more secure and customized. According to our internal analysis, GPT-4 is 82% less likely to respond to requests for illegal content and 40% more likely to provide factual answers than GPT-3.5. ”
The self-test also shows that GPT-4 seems much more complex and intelligent. CEO Patrick Zimmermann has tested the new model himself and is convinced: “GPT-4 understands more complex queries better. You can incorporate a lot of context into the prompt; the so-called instructions can be significantly more complex than before.” Why is that: GPT-3, which was considered the largest language model at the time, was trained with 175 billion parameters. By way of comparison, GPT-4 is trained with 100 trillion parameters.
Which is better now?
Both GTP-3 and GTP-4 each have advantages and disadvantages that should be considered when choosing the appropriate model. While GTP-3 can solve fundamental problems faster due to its smaller number of parameters and data sets, GTP-4 offers higher accuracy for more demanding tasks due to its larger set of parameters and larger data set volume.
There is therefore no uniform recommendation as to which model is more suitable. GTP-3 is often the better choice for simpler tasks, while GTP-4 is preferred when higher accuracy is important for more complex tasks.
What Is GPT-4o?
GPT-4o (the "o" stands for "omni") is OpenAI's newest and most powerful AI model. It was released on May 13, 2024, and will be the new default model in ChatGPT starting at the end of April 2025—both in the free and paid versions. However, please note that GPT-4o's use in the free plan is limited and has lower usage capacity. GPT-4o is a multimodal language model and can process not only text but also code, images, audio, and videos.
Since the update (in November 2024), GPT-4o has an updated knowledge base up to June 2024, enabling it to provide more precise and up-to-date information. In addition, the token capacity has been increased from 4,096 to 16,384 tokens, enabling it to efficiently process even longer texts and extensive content. Users can now also speak directly to GPT-4o, as spoken language processing is now possible. However, this feature is currently only available for paid versions of GPT. In terms of performance, speed, and the quality of responses, the model far surpasses its predecessors. Among other things, grammar and phrasing in languages other than English have also reportedly improved significantly.
What Should Be Considered When Using GPT-4o?
As mentioned above, it is important to verify information presented as facts – this remains the case with GPT-4o as the new standard model.
Furthermore, the AI's output, i.e., the answer provided by ChatGPT, is only as good as the input. This means that if the task/question received by GPT-4o via chat is not sufficiently and well-described, the result will suffer. Sentences or keywords used to obtain a response from ChatGPT are called prompts (singular: prompt). The more precise and well-worded the prompt, the more you can expect from the GPT-4o response.
GPT-4 vs. GPT-4o
With the release of GPT-4o, the initial question was whether the new model would replace GPT-4. It is now clear: GPT-4o is not just a supplement, but has completely replaced GPT-4 in the ChatGPT interface. As of April 30, 2025, GPT-4o has been the new standard model.
GPT-4o scores primarily with its higher speed and lower cost compared to GPT-4. It also offers features that GPT-4 did not natively support, such as image and audio processing. GPT-4o performs better in benchmarks such as MMLU and HumanEval and, according to OpenAI, is particularly impressive in multilingual and visual tasks.
GPT-4, on the other hand, has long offered the clear advantage of being able to render data in real time at any time because it has permanent access to the internet. But since a new update, GPT-4o now has permanent access to the Internet and even with the free version GPT-4.1 mini, users can now receive data in real time:
What Is GPT-4.5?
GPT-4.5 is OpenAI's latest AI model and has been available since February 27, 2025. It has been optimized for even more natural and intuitive conversations – instead of strict step-by-step reasoning, it relies on fluid, understandable communication. The new model is particularly strong at everyday questions, texts, and summaries, while complex logic and programming are de-emphasized. Thanks to improved voice guidance, greater accuracy, and fewer hallucinations, GPT-4.5 is designed to feel even more human.
Originally, GPT-4.5 was only available to Pro subscribers, but access has since been expanded to Plus, Team, Enterprise, and Edu plans (as of April 2025).
It is important to note, however, that OpenAI plans to remove GPT-4.5 from the API. Developers will have access to GPT-4.5 via the OpenAI API until July 14, 2025, after which they will have to switch to a different model. GPT-4.5 will be removed from the API because it was expensive, computationally intensive, and intended only as a research preview. Developers should instead use the more efficient and cost-effective GPT-4.1.
GPT-4 vs. GPT-4.5
According to OpenAI, GPT-4.5 stands out primarily for its natural conversational skills. The new model is said to better understand social nuances, sound more human, and formulate more clearly. Furthermore, tests such as SimpleQA show that, with an accuracy rate of 62.5%, GPT-4.5 is significantly less hallucinatory and provides more precise facts than GPT-4, which achieved only 38.2% in the same test. However, GPT-4.5 is less suited to complex logical analyses—here, specialized models remain the better choice.
What Is GPT-4.1?
GPT-4.1 is a specialized AI model from OpenAI that was introduced directly into ChatGPT for paying users in May 2025. Unlike GPT-4o, which was optimized for broad multimodality (text, image, audio, video), GPT-4.1 focuses on precision, reliability, and technical tasks—particularly in programming and web development.
GPT-4.1 was originally only available via the API and enjoyed great popularity there, especially among developers. Due to high demand, it is now also available in ChatGPT via the model selection ("More Models")—for users with Plus, Pro, or Team plans. The model offers similar usage limits to GPT-4o, but, according to OpenAI, impresses with even more precise instruction following, improved coding capabilities, and more stable performance on complex tasks.
A more compact version has also been released: GPT-4.1 mini. Since May 2025, it has replaced the previous GPT-4o mini model as the standard fallback for free accounts once their GPT-4o limit is reached.
Comparison of Current GPT Models (as of July 2025)
Which version is suitable for what? The following overview shows the current ChatGPT models, including their strengths, areas of application, and limitations.
AI Chatbot for Customer Communication
It's impressive what ChatGPT can now do: generate text, answer questions, and even program. But GPT-4 alone isn't designed for use in a company's customer communication. The responses are often unpredictable, difficult to control, and not always brand-consistent – a risk that no one can afford in professional customer dialogue.
