About GPT-4.5 Preview

GPT-4.5 Preview is OpenAI's latest and most advanced language model, designed to enhance natural conversation, emotional intelligence, and creativity. It is the largest and strongest general-purpose model in OpenAI's portfolio, offering a more natural interaction experience with improved understanding of nuance and user intent. GPT-4.5 supports features like file and image uploads, web search, and the canvas tool, making it versatile for tasks such as writing, content generation, and programming assistance. It has a broader knowledge base and reduced hallucination rates compared to previous models, such as GPT-4o, with a significant decrease in inaccuracies. The model excels in tasks requiring open-ended thinking, problem-solving, and communication, but lacks detailed step-by-step logic and multimodal capabilities like audio or video output. GPT-4.5 is available in Azure AI Foundry and through ChatGPT for Pro users, with plans to expand access to other tiers. Its development involved advanced training techniques, including supervised fine-tuning and reinforcement learning from human feedback, to align the model with human expectations and improve its performance.
