Access and Availability
GPT-4.5 is now available to ChatGPT Pro subscribers in a research preview. It will be accessible to other users, including ChatGPT Plus and Team subscribers, within the next week. Enterprise and Education users will get access shortly afterward. OpenAI plans to expand the model’s availability as testing continues.
Key Features
The new model offers several notable improvements. GPT-4.5 supports web search, file uploads, and image recognition. It also introduces a canvas feature that allows for collaborative writing and coding. The model has an enhanced emotional intelligence (EQ), making interactions feel more natural and human-like. Users can expect more accurate and creative responses in areas like writing, programming, and problem-solving.
Improved Accuracy and Reduced Hallucinations
One of the most significant updates to GPT-4.5 is its ability to reduce hallucinations—instances where the AI generates false information. The model’s expanded knowledge base and better understanding of context help it produce more reliable answers. While it still has room for improvement in areas like math and science, GPT-4.5 excels in language-related tasks.
Performance Benchmarks
Benchmark tests show that GPT-4.5 performs better than previous models in language tasks. However, it lags in math and science when compared to some smaller models, like o3-mini. Despite this, GPT-4.5 outperforms its predecessors in creativity and emotional intelligence, providing a better user experience in practical applications.
Applications and Use Cases
Developers can utilize GPT-4.5 for various applications. The model is well-suited for writing assistance, coding, and complex task automation. Its strong EQ makes it a valuable tool for communication, coaching, and learning. Additionally, it can handle multi-step workflows and brainstorming sessions effectively.
Cost and Future Plans
GPT-4.5 is a highly compute-intensive model, making it more expensive to run than previous versions. OpenAI is evaluating its long-term viability in the API due to these higher costs. Developers are encouraged to provide feedback, which will help OpenAI refine the model’s future applications.
Conclusion
GPT-4.5 marks a significant leap in AI development. With enhanced emotional intelligence and improved capabilities, it offers more reliable and creative solutions than its predecessors. OpenAI continues to explore the full potential of this model, and users are invited to help shape its future.
