On February 28th, OpenAI officially announced the launch of its latest AI model, GPT-4.5, via an official blog post. OpenAI touts this model as its largest and best-performing chat model to date, initially releasing it as a research preview to ChatGPT Pro users.
GPT-4.5 boasts significantly expanded pre-training and post-training scales, directly enhancing its unsupervised learning capabilities. The model reportedly achieves breakthroughs in pattern recognition, connection building, and creative generation. Early testing feedback indicates a more natural and fluid interaction experience, a broader knowledge base, and a deeper understanding of user intent. Furthermore, GPT-4.5 demonstrates impressive "emotional intelligence," improving writing, coding skills, and problem-solving abilities while significantly reducing "hallucinations" and increasing overall reliability.
GPT-4.5 achieves further improvements in unsupervised learning through increased computational and data scale, architectural optimizations, and the introduction of innovative technologies. Its expanded knowledge base and deeper understanding of the world provide users with a more accurate and reliable interactive experience. Simultaneously, GPT-4.5's superior skill in understanding user intent and its effectiveness in reducing "hallucinations" elevate the model's reliability to a new level.
It's worth noting that GPT-4.5 employs new scalable techniques, enabling the training of larger, more powerful models using data from smaller models. This innovation enhances GPT-4.5's controllability, understanding of subtle nuances, and natural conversational abilities. GPT-4.5 also excels in writing and design, showcasing strong creativity and aesthetic intuition.
GPT-4.5 has a wide range of applications, including but not limited to writing assistance, communication, learning, guidance, and brainstorming – areas requiring higher emotional intelligence and creativity. Moreover, the model demonstrates strong capabilities in agent planning and execution, supporting multi-step coding workflows and the automation of complex tasks.
Although GPT-4.5 is a large, computationally intensive model with a higher cost than GPT-4, OpenAI states it's evaluating the long-term provision of GPT-4.5 services via its API. GPT-4.5 will initially be rolled out to Pro users, followed by Plus and Team users next week, and subsequently expanded to Enterprise and Edu users. Notably, users can already experiment with GPT-4.5 on Microsoft's Azure AI Foundry platform.
