Key Takeaways
On February 27, 2025, OpenAI officially announced the research preview of GPT-4.5, calling it its most advanced and natural AI model yet.
The model is designed to provide more intuitive conversations, better contextual understanding, and improved problem-solving abilities.
“Interacting with GPT-4.5 feels more natural. Its broader knowledge base, improved ability to follow user intent, and greater EQ make it useful for tasks like improving writing, programming, and solving practical problems.”
Additionally, OpenAI claims that GPT-4.5 presents inaccurate information less frequently than previous models, reducing hallucination rates compared to GPT-4o and o1.
Despite these improvements, OpenAI CEO Sam Altman stated that GPT-4.5 is not designed to break AI benchmarks but instead focuses on providing a more human-like AI experience.
“This isn’t a reasoning model and won’t crush benchmarks. It’s a different kind of intelligence, and there’s a magic to it I haven’t felt before.”
Who Can Use GPT-4.5?
Initially, GPT-4.5 is only available to ChatGPT Pro users who pay $200 per month.
OpenAI originally planned a simultaneous launch for ChatGPT Plus ($20/month) users, but the rollout was delayed due to a shortage of high-performance GPUs.
“We really wanted to launch it to plus and pro at the same time, but we’ve been growing a lot and are out of GPUs. We will add tens of thousands of GPUs next week and roll it out to the plus tier then.”
According to Alex Paino, OpenAI’s research lead, GPT-4.5 will expand to ChatGPT Plus and Team subscriptions next week, followed by ChatGPT Edu and Enterprise users the week after.
GPT-4.5 is also available through Microsoft’s Azure AI Foundry, as announced by Microsoft CEO Satya Nadella.
Microsoft, which has invested over $13 billion in OpenAI, provides computing resources for OpenAI’s models and integrates them into its cloud and enterprise services.
Pricing: GPT-4.5 Comes at a Steep Cost
GPT-4.5 is not just OpenAI’s most advanced model—it’s also its most expensive.
The company has set API pricing at $75 per million input tokens and $150 per million output tokens, a staggering increase from GPT-4’s $2.50 per million tokens.
Altman acknowledged the cost, calling GPT-4.5 a “giant, expensive model.”
This 30x price increase is attributed to higher computational demands, need for increased GPU power, and more advanced AI training processes
Due to the high cost, GPT-4.5 is expected to be used primarily by large enterprises, developers, and research institutions rather than everyday consumers.

The AI race has also affected the stock market. Last month, Nvidia’s market capitalization dropped nearly $600 billion in a single day after investors reacted to the rise of DeepSeek’s AI models, which take a more computationally efficient approach.
Meanwhile, OpenAI is currently in discussions for a $40 billion funding round, which could push its valuation to $340 billion, making it the most valuable AI company in the world.
What’s Next? The Road to GPT-5
While GPT-4.5 marks a major milestone, OpenAI has confirmed that its primary focus is now on GPT-5.
This suggests that GPT-5 will introduce more advanced reasoning capabilities, potentially making AI more logical, problem-solving, and decision-driven.
Additionally, OpenAI has hinted at future “Operator AI” assistants that can perform tasks on the internet, such as booking tickets, managing schedules, and retrieving complex information from multiple sources.
For now, GPT-4.5 serves as a bridge between existing AI capabilities and the next era of intelligent, reasoning-based AI models.
GPT-4.5 raises the bar for AI interaction, offering a more human-like conversational experience with fewer hallucinations.
However, its high cost and limited availability make it inaccessible to most users.
Key Challenges OpenAI Faces Moving Forward:
With GPT-5 in development, OpenAI’s next challenge will be ensuring that AI advancements remain accessible rather than exclusively benefiting high-paying customers.
The big question remains: Is GPT-4.5 a groundbreaking step toward AI’s future, or an expensive luxury that only a select few can afford?
