OpenAI has released a long-awaited update to its popular language model, ChatGPT 4.5, also known as Orion. GPT-4.5 is OpenAI’s largest and most advanced language model to date. The new version of the model brings significant improvements in creativity, emotional intelligence, information accuracy, and context understanding. So let’s take a closer look at it.
1. Why does GPT-4.5 understand the world better?
GPT-4.5 better “understands the world” thanks to several key improvements in the way it was designed and trained:
Advanced unsupervised learning scaling:
The model was trained on massive text datasets without direct supervision, allowing it to “autonomously” discover linguistic structures, word relationships, and contexts. This gives GPT-4.5 a more intuitive grasp of linguistic nuances, which translates into a better understanding of content and user intent.
Intensive training on Microsoft Azure AI supercomputers:
The use of powerful computing resources has enabled the processing of much larger amounts of data and the use of more complex model architectures. Such mass-scale training allows for:
Expanding the knowledge base, which results in a deeper understanding of reality.
Improving pattern recognition mechanisms, which helps minimize errors such as so-called “hallucinations” – i.e. generating inaccurate or false information.
Better combining unsupervised learning with reasoning:
Although GPT-4.5 relies primarily on unsupervised learning, modern techniques also allow it to effectively use elements of reasoning. This allows the model to not only analyze data, but also interpret and apply it in context, resulting in more precise and accurate answers.
Optimization of training architecture and techniques:
Improvements in the model architecture and the use of advanced training techniques (such as a combination of traditional training and reinforcement learning) allow for better detection of subtle relationships and contexts. As a result, GPT-4.5 is better able to “understand” both the literal and figurative meaning of texts, making it more flexible and reliable in interpreting human speech.
In short, by combining extensive, scalable training on massive datasets, a modern architecture, and powerful computing resources, GPT-4.5 gains the ability to understand the world more deeply and intuitively. This approach enables it to provide more accurate, consistent, and empathetic responses, which is crucial in everyday interactions with users.
2. Does GPT-4.5 actually generate more creative responses?
Early tests show that interactions with GPT-4.5 are much more natural, fluid, and creative. The model generates higher quality, more engaging, and vivid statements, better tailored to the user’s intent. Let’s compare the capabilities of Orion and the previous version of the model using 3 prompts:
Prompt 1: “Describe briefly but creatively an autumn afternoon.”
GPT-4: “The autumn afternoon is cool and leaves are falling from the trees.”
GPT-4.5: “The autumn afternoon smells of wet earth and warm tea, while the sun streaks golden through the reddening leaves. The wind whispers softly through the branches, carrying memories of summer past.”
Prompt 2: “Describe briefly but creatively a morning walk in a city park.”
GPT-4: “A morning walk in a city park is a peaceful moment when nature comes to life and people enjoy the fresh air.”
GPT-4.5: “A morning walk in a city park is like immersing yourself in living poetry – fog gently drifts between the trees and the first rays of sunlight break through the leaves, waking up the city to the joyful symphony of the day.”
Prompt 3: “Create a creative vision of the future where nature and technology coexist.”
GPT-4: “In the future, nature and technology will coexist, creating a harmonious reality where people enjoy advanced technology while caring for the environment.”
GPT-4.5: “Imagine a world where glass skyscrapers blend into lush, green forests, and digital trees grow alongside real ones. Interactive gardens pulsate with energy, and the symbiosis of technology and nature creates a poetic mosaic of a new era.”
Of particular note is the direct address to the recipient (“Imagine…”) and… the response time. Generating the text (which, by the way, is longer) took noticeably less time in the case of Chat GPT 4.5.
3. How does GPT-4.5 deal with emotions?
GPT-4.5 shows significant improvement in emotional intelligence by using Reinforcement Learning with Human Feedback (RLHF). This is a training technique in which the AI model learns not only from raw data, but also from feedback from humans evaluating its responses. Experts analyze the different variants of the responses generated by the model and choose the ones that are most relevant, empathetic, and in line with the user’s intention. Based on this, a special reward model is created that teaches GPT-4.5 what responses it should prefer to be more useful, natural, and supportive in the conversation. This allows the model to better interpret emotions, avoid inappropriate responses, and provide more empathetic and personalized responses. New training techniques increase the model’s ability to pick up on subtle emotional cues and intentions, which translates into more empathetic, natural, and situationally appropriate responses. The model not only understands words, but also the emotional context, making it a better conversation partner.
3.1 How does GPT-4.5 interpret emotions?
GPT-4.5 is trained on human interactions and expert ratings, allowing it to:
Recognize tone of voice – it can distinguish between a happy tone and a sad or sarcastic one.
Adjust response style – when a user is expressing frustration, the model will respond with a more calm, supportive tone, while in a happy context it may use more enthusiastic language.
Better response to sensitive topics – with RLHF, the model avoids trivializing difficult emotions and instead offers more supportive and empathetic responses.
3.2 Empathy in practice
Through RLHF, GPT-4.5 learned to adjust his responses to sound more natural and appropriate to the situation:
Example:
User prompt: “I feel down today.”
GPT-4 (without RLHF): “I’m sorry to hear that. I hope it gets better.”
GPT-4.5 (with RLHF): “I’m sorry you feel that way. Do you want to talk about it? Maybe I can help, suggest something to cheer you up or take your mind off things?”
We see that the GPT-4.5 response is more caring, attuned to the user’s emotions, and offers the opportunity to continue the conversation in a supportive way.
3.3 Fewer “emotional” errors and more naturalness
Thanks to RLHF, the model avoids misinterpreting emotions that could lead to inappropriate reactions. GPT-4.5’s responses are more natural, fluid, and tailored to the user’s needs, making the conversation with AI more human. In short, GPT-4.5 not only understands emotions better, but also responds to them appropriately, making it a more effective tool in interactions that require empathy and sensitivity.
4. Does GPT-4.5 make fewer errors?
GPT-4.5 has significantly reduced the number of so-called “hallucinations”—false or fictitious information that AI models generate when they don’t have enough data to provide an accurate answer. Hallucinations can include false facts, misinterpretations, or even completely made-up content that sounds plausible at first glance. To mitigate this problem, OpenAI has made several significant improvements to the new version of the model. GPT-4.5 has been trained on an even larger and more diverse dataset, allowing it to better understand reality and fill in missing information with guesswork less often. At the same time, the new model architecture improves the way it processes information and recognizes patterns, which increases the consistency and precision of the answers it generates.
In addition, the use of reinforcement learning based on human feedback (RLHF) plays an important role. Thanks to this technique, experts evaluate the model’s responses and indicate which are more accurate and consistent with reality, which allows GPT-4.5 to distinguish true information from false information more effectively. As a result, the model is less likely to provide non-existent facts as certainties. Uncertainty detection mechanisms have also been improved, thanks to which GPT-4.5 better recognizes situations in which it lacks data. Instead of providing false information with confidence, it uses more cautious formulations, suggesting the user to check reliable sources.
Another new feature is greater flexibility in updating knowledge through integration with dynamic data sources and the ability to adjust the model to specific needs through fine-tuning. Thanks to this, GPT-4.5 reduces the risk of providing outdated information and better adapts to real, changing conditions. While no AI is completely free from errors, the improvements in this version make the model much more precise, logical, and aware of its own limitations, making its answers more reliable and useful in everyday use.
5. Is GPT-4.5 the basis for future reasoning models?
Chat GPT-4.5, also known as Orion, is a significant step forward in the development of language models, focusing on advanced unsupervised learning. OpenAI plans for such models to become a solid foundation for future systems developing advanced logical and technical reasoning capabilities. In the future, it is expected to integrate unsupervised learning methods with reasoning techniques, which will increase the versatility of the AI.
In terms of further plans, OpenAI is working on the GPT-5 model, which is expected to introduce significant improvements. According to the information, GPT-5, also known as Orion, has been in development for 18 months, but has encountered delays and high costs associated with training the model. Challenges include a lack of sufficient and high-quality data and competition for computing resources. To overcome these limitations, OpenAI is hiring experts to generate new data and is exploring the possibility of using synthetic data created by existing AI models, although this is associated with certain risks.
Despite these challenges, Microsoft is preparing to host the upcoming GPT-4.5 and GPT-5 models on its servers. GPT-5, integrating more OpenAI technologies, including the new o3 reasoning model, is expected around the end of May. The goal is to create a more advanced AI system, approaching artificial general intelligence (AGI). It also plans to unify the o-series and GPT models to improve user experience by eliminating the need to choose the right model for a specific task.
The introduction of GPT-5 also aims to simplify OpenAI’s product offering. Currently, users have to choose between different models, which can be complicated. The new system is supposed to automatically analyze content and choose the best model, increasing usability in different contexts. Importantly, GPT-5 is to be available in an “unrestricted way” as a free version, which could increase its accessibility to a wider range of users.
6. How does GPT-4.5 ensure user security?
Security remains a key aspect of all OpenAI models, and GPT-4.5 is designed to minimize the risk of erroneous, malicious, or inappropriate responses. The model has undergone extensive testing against a comprehensive Preparedness Framework that includes analyzing potential threats, mitigating the risk of generating malicious content, and implementing measures to prevent misuse. Using advanced supervision, the model is constantly monitored for correctness and security.
One key element of ensuring security is the combination of traditional supervised training (SFT) and reinforcement learning based on human feedback (RLHF). This allows the model to better understand the context and intent of the user, allowing it to avoid inappropriate content and adapt responses in a more ethical and consistent way. Human judgment also helps eliminate biases and reduce the risk of generating content that could be disinformative, aggressive, or dangerous.
Additionally, GPT-4.5 has been equipped with uncertainty detection mechanisms that allow it to better recognize situations where it does not have enough data to provide a confident response. Rather than providing misinformation, the model is more likely to suggest fact-checking with credible sources or being cautious with its claims. Another important aspect of security is implementing content filters and abuse mitigation systems that help detect and block potentially harmful queries.
