OpenAI has introduced GPT-4.5, its latest and most advanced AI model, designed to push the boundaries of unsupervised learning and human-like interaction. This research preview aims to showcase GPT-4.5’s capabilities, offering deeper knowledge, improved emotional intelligence (EQ), and more accurate pattern recognition all while being more computationally intensive and expensive than its predecessor, GPT-4o.

The launch of GPT-4.5 marks a significant step in scaling AI models, combining unsupervised learning with advanced pre-training techniques. According to OpenAI, unsupervised learning boosts the model’s intuition and understanding of the world, while scaling reasoning allows AI to tackle complex STEM problems by forming logical "chains of thought." GPT-4.5 expands the unsupervised learning approach, using Microsoft Azure AI supercomputers for training.

In early testing, GPT-4.5 showed smoother, more intuitive conversations. OpenAI highlighted that the model is better at following user intent, recognizing subtle human cues, and creatively generating responses. The model’s emotional intelligence has also been refined, making it more collaborative and effective for tasks like writing assistance, problem-solving, and brainstorming.

One of the main selling points is GPT-4.5’s improved collaboration with human users. The AI interprets nuanced language and implicit expectations more naturally, which OpenAI credits to scalable training methods that use data from smaller models to enhance larger ones. As a result, GPT-4.5 appears more "human-like" in its interactions.

Despite its advancements, GPT-4.5 is not without limitations. Unlike OpenAI’s reasoning models like o1 and o3-mini, which "think" before responding, GPT-4.5 focuses on scaling pre-training rather than real-time reasoning. This makes it a powerful, general-purpose model but not a direct replacement for logic-driven AI systems.

Businesses interested in testing GPT-4.5 can access it through ChatGPT Pro, with plans to expand to Plus, Team, and Enterprise users. Developers can also preview the model via the Chat Completions API, Assistants API, and Batch API.

However, OpenAI acknowledges that GPT-4.5's computational demands may affect its long-term availability. The company is still assessing whether to continue offering it through APIs, balancing the need for cutting-edge AI with sustainable model deployment.

While GPT-4.5 shows clear progress in AI’s ability to understand and interact with humans, its high costs and focus on unsupervised learning raise questions about its practicality for businesses. Still, the model opens the door for further AI innovation, combining intelligence and collaboration in ways that could reshape how we use AI in daily tasks and strategic decision-making.
