Two days ago, on 27 Feb 2025, OpenAI dropped GPT-4.5, expectations were sky-high. But instead of a groundbreaking leap forward, we got a model prioritizing emotional intelligence over raw reasoning power. This model has left the AI researchers in a deep divide. Some experts call this model a game-changer, while others, like AI researcher Gary Marcus, dismiss it as a “nothing burger.” But the real question? Are the economics of AI finally catching up with its ambitions?
Is there any “Value” to the “Vibes”?
Sam Altman himself described GPT-4.5 as “the first model that feels like talking to a thoughtful person.” Others, like Ben Hylak, compared it to “the Midjourney moment for writing.” It’s a step forward in making AI-generated content more natural, expressive, and human-like.
But is that enough? While some praise its ability to write beautifully, many testers noted that it lacks real improvements in reasoning and can even seem lazy on complex tasks. “Vibes” don’t always translate to improved performance or enhanced results, and in an AI arms race where efficiency and accuracy matter most, that’s a big issue.

The Real Question: Is GPT-4.5 Too Expensive?
The biggest question around GPT-4.5 isn’t about its quality, but it all comes down to the cost. OpenAI charges $75 per million input tokens and $150 per million output tokens. Making it almost 10-25x more expensive than the latest models like Grok 3, Gemini 2.0 Flash or DeepSeek R1.
To put it simply, GPT-4.5 might be too expensive for its good. If you’re building an AI-powered chatbot, automation tool, or content generator, costs can skyrocket into the millions. Even OpenAI admits that GPT-4.5 is “very large and compute-intensive,” and they’re still unsure if they’ll even continue offering it via API in the long term.
For businesses and developers, that raises a massive red flag. If OpenAI isn’t confident about its long-term viability, why should anyone else be?

Did GPT-4.5 Lead to a Stock Market Crash?
Stock market has been on a tumble for quite some time but the release of GPT4.5 did make it own mark at the trading market. Right around the time GPT-4.5 was released, NVIDIA’s stock price dropped significantly. Was it a coincidence? Maybe. But the AI industry’s reckless spending habits are finally being questioned, and GPT-4.5 might be the first victim of this new reality.
For years, companies have thrown blank checks at AI development, betting big on the next breakthrough. But now, the days of infinite funding seem numbered. Investors are realizing that even the most impressive AI models need to be financially sustainable, and right now, GPT-4.5 isn’t.

What’s Next for OpenAI?
OpenAI finds itself in a tricky position. On one hand, they’ve created an impressive model that feels more human than ever. But on the other hand, they’re burning cash at unsustainable levels, and their pricing model alienates the very businesses that rely on their technology.
They need a more sustainable approach—and fast. The industry is at a crossroads: either AI models become more cost-effective and scalable, or they risk pricing themselves out of relevance.
End Note
The answer to the question, “Was GPT-4.5 worth it?” – not quite. While the model does an impressive job at humanizing responses and generating more natural, emotionally intelligent text than any other LLM on the market, it falls short in terms of true innovation.
Despite its improvements in fluency and engagement, GPT-4.5 doesn’t bring any groundbreaking advancements in reasoning, problem-solving, or handling complex tasks. For a model that comes with a steep price tag—10-25x higher than competitors—its value proposition feels questionable. Unless cost efficiency isn’t a concern, GPT-4.5 may not be worth the investment.
