GPT-4.5: OpenAI’s Most Interesting Model Yet?

2025 has already been generous for AI-related releases like DeepSeek and Claude AI. Therefore, well-known for Chat GPT, OpenAI has to keep up with the competition. And they seem to thrive in it: GPT 4.5, launched in February 2025, is called one of the most effective and innovative chatbots released by the company. What is so promising about the GPT 4.5 release, and what new features can it boast? Let’s dive deeper into one of the most intriguing AI models.

What is Chat GPT 4.5

OpenAI experts call Chat GPT-4.5 “the strongest GPT model”. It is available for Pro and Plus subscribers and developers and promises an improved and more natural interaction with humans, fewer hallucinations, and more accurate results than the previous GPT versions.

“By scaling unsupervised learning, GPT‑4.5 improves its ability to recognize patterns, draw connections, and generate creative insights without reasoning,” states the official OpenAI website.

OpenAI still sees scaling its models as a development strategy, making GPT-4.5 the most massive among the company’s chatbots.

“GPT‑4.5 is an example of scaling unsupervised learning by scaling up compute and data, along with architecture and optimization innovations. GPT‑4.5 was trained on Microsoft Azure AI supercomputers. The result is a model that has broader knowledge and a deeper understanding of the world, leading to reduced hallucinations and more reliability across a wide range of topics,” say the OpenAI representatives introducing the new model.

What features does OpenAI GPT 4.5 include

What new features will GPT-4.5 likely include has been a hot topic long before the official release. Here’s what the new model looks like:

• supports web search;
• includes canvas feature allowing work on text and code;
• supports uploads of files and images;
• allows generating visual content;
• maintains more natural dialogue;
• provides sources of information that it used.

How does GPT-4.5 compare to GPT-4 in terms of capabilities

First and foremost, the GPT-4.5 model is bigger than its predecessors, which allows it to deal with more complex problems and provides a better understanding of human needs and intentions, guaranteeing a more accurate output. The logic is simple: the more the model knows, the less it has to make up to produce a relevant response, hence the less it hallucinates.

GPT-4.5 also demonstrates more creativity, which is especially helpful in requests related to design, writing, and programming.

“Broader knowledge base, improved ability to follow user intent, and greater “EQ” make it useful for tasks like improving writing, programming, and solving practical problems,” explain the OpenAI experts.

AI specialists compare chatbot models according to four parameters: consciousness, rationality, speed, and precision. GPT-4.5 is believed to exceed GPT-4 by all of them, except for the speed.

“Despite potential improvements in efficiency and optimization, GPT-4.5’s increased size and complexity may outweigh these gains, resulting in slower inference times compared to GPT-4o,” explain Ask AI Chat apps experts.

However, they believe the decreased speed is worth the benefits the GPT-4.5 model offers compared to GPT-4 version:

“GPT-4.5 may demonstrate a better understanding of context, logic, and causality, potentially allowing for more accurate and insightful responses.

GPT-4.5 could show a 5-15% reduction in biases or logical fallacies compared to GPT-4o.

GPT-4.5 could potentially demonstrate a 12-25% improvement in precision over GPT-4o,” states the website.

How to implement GPT 4.5 responsilbly

No AI model is perfect, and GPT-4.5 is no exception. While the model demonstrates more creativity and is able to provide the sources it used, minimizing the risk of AI-giarism, it is still common that the chatbot mentions irrelevant or made-up sources, or generates inaccurate information. Hence, like any AI tool, GPT-4.5 should be introduced responsibly.

• Consider an AI chatbot as a brainstorming buddy, but never ask it to do the job for you – it’s dishonest and violates academic integrity and working ethics.
• Always fact-check the AI chatbots’ output and look for trustworthy resources.
• In academic writing, attribute the sources you use – including Chat GPT!
• Check for plagiarism to avoid accusations and copying repercussions – sometimes, chatbot output is not original.
• Use TraceGPT AI checker to ensure your writing sounds authentic, and edit it before publishing if needed.

The bottom line

In a nutshell, Chat GPT-4.5 is a step towards upgrading the model’s soft skills.

• While characteristics like creativity, emotional intelligence, and intuition are hard to measure, GPT-4.5 shows better results with tasks in writing, coding, languages, and design, demonstrating less effective performance in maths and sciences.
• The new model predicts and understands human emotions and interactions better, which allows AI to interpret the prompts more accurately, guaranteeing higher emotional intelligence and relevancy.
• Chat GPT-4.5 is not a universal solution and cannot be considered the most advanced model for all tasks. It is supposed that in the future, the system will be able to select the best GPT model depending on the user’s request, switching between them to tailor the model’s capabilities to the user’s needs. Meanwhile, the best we can do is learning about different models’ particularities, and choose the one that matches our requests the most.
