What makes GPT-4.5 different?
GPT-4O introduces multimodal capabilities and faster processing speeds, while GPT-4.5 focuses on perfecting AI’s ability to understand nuances, engage in meaningful conversations, and provide insightful responses.
According to Mia Glaese, Vice President of Research at Openai, “What makes this model unique is its ability to have enthusiastic, intuitive, naturally flowing conversations, and we think it has a deeper understanding of what users want.”
Key improvements include:
- Enhanced EQ: The model better understands user intentions, recognizes subtle cues and responds with greater empathy.
- Reduced hallucinations: Advances in unsupervised learning have greatly reduced the inaccuracy of AI generation.
- Stronger Pattern Recognition: GPT-4.5 creates deeper connections between topics, making it more effective in researching and problem solving.
- Improved creativity: Writing, storytelling and brainstorming feels more natural, with richer insights and smoother responses.
Unsupervised learning for smart AI scaling
The development of GPT-4.5 focuses on extending two complementary AI paradigms: unsupervised learning and reasoning. Unlike models such as the O1 and O3-Mini of OpenAI (which decompose complex problems respectively), GPT-4.5’s learning-based model produces responses.
This method can:
- Faster and more natural responses in casual conversations.
- The factual errors are greatly reduced.
- From creative writing to programming, adaptability to various tasks is enhanced.
However, this also means that GPT-4.5’s struggle with explicit logic-based reasoning makes it less suitable for complex mathematical or coding challenges that require multi-step problem solving.
Practical application: gpt-4.5 Expert
OpenAI’s internal testing highlights several key areas where GPT-4.5 shines:
- Content creation: This model produces a more attractive human-like narrative and refined marketing copy.
- Coding Assistance: While not as powerful as a model focusing on explicit reasoning, GPT-4.5 effectively handles multi-step programming instructions.
- Research and Knowledge Inquiry: Less hallucinations provide a more reliable response to academic and professional research.
- Customer Support & Help: Improved EQ makes it ideal for handling subtle customer interactions.
A compelling example in the Openai test involves the model accurately identifying the Trojan woman of Claude Lorrain that set her on fire and explaining its literary significance in Aeneid, thus illuminating the depth of knowledge and context of understanding.
How to access GPT-4.5
Starting today, Chatgpt Pro users can select GPT-4.5 on ChatGpt’s network, mobile device and desktop versions. Plus and team users will get access next week. Developers can also experiment with GPT-4.5 through OpenAI’s API, which supports function calls, structured outputs and visual functions through image input.
However, GPT-4.5 currently does not support multimodal features such as voice mode, video generation or screen sharing, although OpenAI hints about future updates.
The Future of AI: Openai’s Advance
GPT-4.5 marks the end of Openai’s non-operating model. Future iterations will focus on clear reasoning, where AI takes time to process and logically build responses before answering. This shift can redefine AI’s ability to solve complex problems, especially in the STEM field.
As AI research moves towards reasoning-based intelligence, Openai faces fierce competition from companies such as Google and DeepSeek. The industry is now moving beyond simple pattern recognition and AI that can logically destroy complex tasks, and OpenAI’s direction has been explored in its O1 and O3 models.
Meanwhile, GPT-4.5 provides a more natural, engaging chatbot experience, setting new standards for AI-powered conversations. While it may not be the most logically driven model, it represents a critical step towards AI, not just responsive, but can be truly understood.
