OpenAI has begun rolling out its latest AI model, GPT-4.5, to users subscribed to its ChatGPT Plus tier. This highly anticipated release follows its initial launch for ChatGPT Pro subscribers, marking a significant step in AI advancements. But what exactly does GPT-4.5 bring to the table, and how does it compare to other AI models? In this article, we’ll explore its features, pricing, performance, and what it means for the future of AI-powered interactions.
What is GPT-4.5?
GPT-4.5 is OpenAI’s most advanced AI model, built with increased computational power and more extensive datasets than any previous iteration. This AI model aims to offer enhanced natural language processing, improved contextual understanding, and a more refined user experience. However, while it boasts several upgrades, it still faces stiff competition from other AI reasoning models in the market.
Key Features of GPT-4.5:
- Enhanced Context Understanding: Improved comprehension and response coherence.

- Expanded Multilingual Capabilities: Improved fluency and accuracy across multiple languages.
- Greater Adaptability to User Preferences: Customization based on individual user interactions.
Pricing of GPT-4.5
GPT-4.5 is OpenAI’s most expensive AI model to date. Due to its high computational costs, OpenAI has set the following pricing structure for API usage:
- $75 per million tokens (approx. 750,000 words) for input.
- $150 per million tokens for generated output.
These prices are significantly higher than OpenAI’s GPT-4o model, reflecting the model’s increased processing requirements.
Why is GPT-4.5 So Expensive?
The cost of running GPT-4.5 is driven by several factors:
More Data and Compute Power: The larger the model, the more expensive it is to operate.
- Advanced Processing Requirements: Running a model with such deep knowledge and improved contextual retention requires immense computational resources.
- Infrastructure Costs: AI models need vast cloud computing resources, which add to the expenses.
- Exclusive Access for Premium Users: The high cost also acts as a barrier to ensure access remains exclusive to those willing to pay for premium AI capabilities.
- Energy Consumption: The power required to run high-end AI models is significant, adding to the operational costs.
- Continuous Improvements: OpenAI continuously updates its models, requiring ongoing investment in research and development.
Performance & Comparisons
Despite being OpenAI’s most powerful model, GPT-4.5 does not always outperform the latest AI reasoning models from competitors such as Anthropic, DeepSeek, and even OpenAI’s own upcoming models. Benchmarks show mixed results, with GPT-4.5 excelling in certain tasks but lagging behind in others.
Strengths
- Superior rhetorical skills and argumentation: GPT-4.5 can generate more persuasive and well-structured arguments.
- Lower hallucination rates: Less likely to generate false information compared to previous models.
- Enhanced contextual memory and response accuracy: Keeps track of longer conversations and provides more coherent responses.
- Better adaptability across industries: Useful for business, healthcare, finance, and other fields where precise language processing is crucial.
- Multimodal expansion: Potential to integrate text and visual processing seamlessly.
- Increased Efficiency for Business Applications: Automating reports, emails, and content creation more accurately than before.
- Better Handling of Complex Queries: Improved reasoning capabilities allow for more accurate answers to difficult questions.
- Greater Personalization in AI Responses: Enhanced ability to remember user preferences and provide more tailored responses.
Weaknesses
Expensive to operate and maintain: Costs significantly more than GPT-4o and other alternatives.
- Still not the most advanced reasoning AI model in the market: Competing models from Anthropic and DeepSeek are outperforming it in some areas.
- Potential Over-Reliance on Training Data: AI models still struggle with completely novel scenarios that aren’t reflected in their training data.
- Slow Rollout and Limited Access: Many users still do not have access to GPT-4.5 due to its high cost and restricted availability.
- Computational Heavyweight: Requires high-end servers, making it impractical for personal devices.
OpenAI’s Future with GPT-4.5
Due to its high operational costs, OpenAI is still evaluating whether GPT-4.5 will be widely available through its API in the long term. The company is also expected to refine the model further, balancing efficiency with computational expenses. Future iterations may focus on optimizing performance while reducing costs, ensuring broader access to its advanced capabilities.
Possible Improvements in Future Versions:
- Better Cost Efficiency: Reducing computational power requirements while maintaining quality.
- Expanded Multimodal Capabilities: Integrating real-time video, audio, and image processing.
- Refined Ethical AI Implementation: Addressing biases and improving fairness in decision-making.
