Technical Specifications
GPT-4.5 is OpenAI’s largest and most knowledgeable model to date, designed to be more general-purpose than previous reasoning-focused models. It was trained using new supervision techniques combined with traditional methods like supervised fine-tuning and reinforcement learning from human feedback.
Performance Improvements
The model has shown a reduced rate of “hallucinations,” a common issue where AI generates incorrect information. GPT-4.5’s hallucination rate stands at 37.1%, a significant improvement over earlier models like GPT-4o, which had a rate of 61.8%.
User Accessibility
Initially, GPT-4.5 is available to ChatGPT Pro subscribers, who pay $200 per month, as part of a research preview. OpenAI plans to extend access to ChatGPT Plus and Team users in the following weeks, followed by Enterprise and Educational users.
CEO’s Perspective
OpenAI CEO Sam Altman described GPT-4.5 as a “giant, expensive model,” highlighting the substantial resources invested in its development. He also noted that due to GPU shortages, the rollout to all user tiers will be staggered over the coming weeks.
Implications for the AI Industry
The release of GPT-4.5 underscores OpenAI’s commitment to advancing AI technology and maintaining its leadership in the field. The model’s enhanced capabilities are expected to have wide-ranging applications, from content creation and customer service to complex problem-solving and beyond.
OpenAI’s GPT-4.5 represents a significant milestone in AI language modeling, offering improved performance and more human-like interactions. As access expands to a broader user base, the potential applications of this advanced model are vast, promising to transform various industries and aspects of daily life.
