What is GPT-4.5?

GPT-4.5 is an advanced large language model developed by OpenAI and is the latest member of the GPT-n family. The GPT-4.5 model was developed for better reasoning and precise output generation. The GPT-4.5 model analyzes prompts and produces a chain of thought before generating output, just like the Gemini 2.5 Pro model. This approach of the GPT-4.5 model allows it to complete complex STEM and logic problems with high accuracy.

GPT-4.5 Capabilities

The feature that makes the GPT-4.5 model superior to its predecessors is that it has been trained to understand human intent and needs more comprehensively. With its training method, the GPT-4.5 model can understand nuances and natural conversations.

The GPT-4.5 model has higher benchmark scores than its predecessor. The GPT-4.5 model outperforms its predecessors in tasks such as natural language, coding, reasoning, math, and image analysis. The GPT-4.5 model can generate accurate and clear outputs, especially in reasoning, coding, and math tasks, thanks to its training method and chain of thought.

How to Access GPT-4.5?

The first and easiest way to access OpenAI’s GPT-4.5 model is through ChatGPT. To use the GPT-4.5 model through ChatGPT, you need to purchase its Plus or Team subscription. Once you subscribe to Plus or higher tier ChatGPT, you can select the GPT-4.5 model from the right-top drop-down menu. Another way to access the GPT-4.5 model is to use it as an API and integrate it into your local AI tool.

OpenAI’s GPT-4.5 Pricing

To use OpenAI’s GPT-4.5 model via ChatGPT, you need at least a Plus subscription. That means the pricing of the GPT-4.5 model is at least $20. If you are going to use the GPT-4.5 model as an API, you will need to pay $75 per million input tokens, $37.5 per million cached input tokens, and $150 per million output tokens.

Gemini 2.5 Pro vs. OpenAI’s GPT-4.5 Comparison

If you are looking for a reasoning model for your AI tool or to utilize it in your tasks and are stuck between Gemini 2.5 Pro and GPT-4.5, we’ve got you covered. Let’s compare Gemini 2.5 Pro and GPT-4.5 and explore the pros and cons of each!

Gemini 2.5 Pro vs. OpenAI’s GPT-4.5 Performance Comparison

Both Gemini 2.5 Pro and GPT-4.5 models were developed to generate effective output and perform operations on reasoning tasks. When we look at the benchmark results designed to measure the reasoning, math, and coding performance of large language models, it is possible to see that the Gemini 2.5 Pro model has higher scores than the GPT-4.5 model.

In Humanity’s Last Exam benchmark, which is specifically designed to measure the human-level reasoning capabilities of large language models, Gemini 2.5 Pro has a score of 18.8%, while GPT-4.5 has a score of 6.4%. That shows that Gemini 2.5 Pro has higher advanced reasoning capabilities than GPT-4.5. Gemini 2.5 Pro also outperformed GPT-4.5 in visual reasoning, math, and coding benchmarks such as GPQA, AIME 2025, SWE-bench verified, and MMMU.
