OpenAI, the company behind ChatGPT, has introduced GPT-4.5, its latest and most advanced AI model. As competition in artificial intelligence grows—especially with the rise of Chinese AI startup DeepSeek—OpenAI is working hard to stay ahead in the AI industry.
What’s New in GPT-4.5?
The AI industry has seen rapid growth in 2025, with DeepSeek making news for its r1 model, which offers strong performance at lower costs. In response, OpenAI introduced o3-mini, improving AI reasoning and response speed. Now, OpenAI has launched GPT-4.5, its largest and most powerful AI model so far.
Key Features of GPT-4.5:
- Better accuracy – More precise and reliable responses.
- Improved emotional understanding – AI can detect and respond to emotions more naturally.
- More natural conversation – Chat feels more human-like.
- Web search and file uploads – Users can browse the internet and upload files for AI assistance.
- Enhanced Canvas Tool – A better workspace for interactive AI use.
While GPT-4.5 is a big step forward, OpenAI confirms that o3 remains the best AI for complex reasoning tasks. The company also acknowledges that having multiple AI models can be confusing for users. To fix this, OpenAI is planning to launch GPT-5 later this year, which will provide a more unified AI experience.
Who Can Use GPT-4.5?
Currently, GPT-4.5 is available for Pro users at $200 per month. However, OpenAI plans to expand access to ChatGPT Plus, Team, Enterprise, and Edu users soon.
The Future of AI
With AI technology advancing quickly, OpenAI is determined to stay ahead of competitors and continue shaping the future of artificial intelligence.
