OpenAI GPT 4.5

OpenAI just released their newest AI model, GPT 4.5, also known as Orion. This powerful tool came out in late February 2025. It uses more computing power and data than any of OpenAI''s previous models. This is a big step toward creating artificial general intelligence (AGI).

Key Features

GPT 4.5 has several key improvements, especially in how it mimics human behavior. It has stronger intuition and a deeper understanding of emotions. The model was trained using a mix of unsupervised learning, supervised fine tuning, and reinforcement learning from human feedback on Microsoft Azure. Although it is big, OpenAI sees GPT 4.5 as a step towards creating artificial general intelligence (AGI), not as a final model.

Benefits

GPT 4.5 performs better than its predecessor, GPT 4o, in several areas.

Emotional Intelligence GPT 4.5 shows a deeper world knowledge and higher emotional intelligence.

Creative Tasks The model is great at creative tasks like writing and design, responding in a warmer and more natural tone.

Benchmark Tests On OpenAI''s SimpleQA benchmark, GPT 4.5 performs better than GPT 4o and other models in terms of accuracy and makes fewer mistakes.

Use Cases

GPT 4.5''s advanced capabilities make it great for many applications. Its emotional intelligence and creative strengths can be particularly useful in fields like content creation, customer service, and educational tools. The model''s improved accuracy and fewer mistakes make it a reliable choice for tasks needing precision and reliability.

Cost Price

GPT 4.5 is initially available to ChatGPT Pro subscribers, who pay 200 dollars a month. The model will gradually be available to other paid tiers, including Plus, Team, Enterprise, and Edu. OpenAI describes the model as having a giant, expensive architecture, costing 75 dollars per million input tokens and 150 dollars per million output tokens. Developers can access GPT 4.5 via the OpenAI API or the OpenAI Developer Playground.

Funding

The release of GPT 4.5 raises economic questions. OpenAI is evaluating whether to continue serving GPT 4.5 in its API long term due to its high cost. The company is also considering new ways to cover the cost of training and running increasingly pricey frontier models, such as switching to a credit per use system.

Reviews Testimonials

Users have praised GPT 4.5 for its emotional intelligence and creative capabilities, noting that it responds in a warmer and more natural tone compared to previous models. Its improved accuracy and fewer mistakes have also been highlighted as significant advantages.
