What is GPT-4.5
GPT-4.5 isOpenAIThe artificial intelligence model developed by the company was officially released on February 28, 2025. As an upgraded version of GPT-4, GPT-4.5 realizes significant improvements in knowledge breadth, natural interaction and safety. It has a broader knowledge base and is able to provide richer and more accurate information; at the same time, its interactions are more natural and better aligned with human intent.
In addition, GPT-4.5 has undergone extensive safety evaluation to ensure that no harmful or biased content will be generated in the application.The release of GPT-4.5 marks another major breakthrough in OpenAI's AI technology.
GPT-4.5 main features:
- Enhanced pattern recognition and connectivity: GPT-4.5 is able to recognize complex patterns and make correlations more efficiently, generating creative insights.
- Higher emotional intelligence: The model excels in understanding and responding to emotions, making human-computer interaction more natural and intimate.
- Multimodal processing: GPT-4.5 supports processing text, image, audio and other input forms, expanding the range of applications.
GPT-4.5 Technical Advantage:
- Reduced rate of hallucinations: The phantom rate of GPT-4.5 was reduced from nearly 601 TP4T in GPT-4o to 371 TP4T, improving the accuracy and reliability of the generated content.
- Improved reasoning and problem solving skills: GPT-4.5 demonstrates enhanced reasoning and problem-solving skills in complex logic problems and real-world applications.
- Real-time information processing: Real-time integration capabilities to dynamically process and update information to ensure the timeliness of output content.
GPT-4.5 Usage Scenarios:
- Content Creation: With its high emotional intelligence and creativity, the GPT-4.5 can be used to write articles, stories, ad copy, and more.
- Programming Aids: Assist developers with code writing, debugging and optimization to improve development efficiency.
- The field of education: Acts as an intelligent tutor, answering student questions and providing personalized learning advice.
- Customer Service: Provide intelligent customer service solutions for enterprises to improve user satisfaction.
GPT-4.5 Fee Model:
- High cost of use: GPT-4.5 is priced at $75/million tokens, much higher than GPT-4's $2.50.
- Subscription Service: GPT-4.5 is currently available as a research preview to ChatGPT Pro users and Microsoft Azure AI Foundry enterprise customers.
GPT-4.5 Usage:
- ChatGPT Platform: Subscribers to the ChatGPT Pro service can experience the power of GPT-4.5 directly on the platform.
- API Integration: Enterprise customers can integrate GPT-4.5 into their own applications and services through OpenAI's API for customized functionality.
