GPT 4.5 Is Here but Don’t Expect a Huge Leap
OpenAI just pushed out GPT 4.5, and the buzz is…well, pretty chill. The company’s own benchmarks say it’s a bit better than GPT-4 or GPT-4o, but not by a landslide. Some folks even called the launch underwhelming, and honestly, I get why. The model is more expensive to run, and the improvements are subtle unless you’re really paying attention.
What does that mean for you? If you’re hoping for a chatbot that suddenly feels like your best friend, you’ll notice GPT 4.5 is more concise and a bit more human in its tone. It’s not a mind-blowing upgrade, but it does feel less stiff, especially when you’re asking personal or sensitive questions.
Using GPT 4.5 on Perplexity AI Is Only for Pro Users
If you’re itching to try GPT 4.5, you’ll need a Perplexity Pro subscription. The free version doesn’t offer this model, probably because of the high costs. Here’s the deal: you get 10 credits per day to use GPT 4.5. Once you run out, you’ll have to wait until the next day for more. That makes it something you’ll want to save for when it really matters.
To switch to GPT 4.5, just head to your Perplexity settings, go to the account menu, and pick GPT 4.5 from the list of models. Super easy, but remember those credits!
GPT 4.5 vs. GPT-4o vs. Claude 3.7 Sonnet—What’s Different?
Let’s get into the details. I put GPT 4.5, GPT-4o, and Claude 3.7 Sonnet head-to-head with the same questions. Here’s what stood out:
- GPT 4.5 gives answers that feel more natural and less like a script.
- It’s slower. Sometimes painfully so. That could be because the model is bigger, or maybe everyone’s trying it at once.
- GPT-4o is way faster but tends to give longer, less focused answers.
- Claude 3.7 Sonnet is a nice middle ground: faster than GPT 4.5, more concise than GPT-4o, but still not quite as “human” as GPT 4.5.
Here’s a quick table for the comparison:
| Feature | GPT 4.5 | GPT-4o | Claude 3.7 Sonnet |
|---|---|---|---|
| Human-like | 👍 Most natural | 😐 Okay | 👍 Close |
| Speed | 🐢 Slow | ⚡ Fast | 🚀 Faster |
| Cost | 💸 Expensive | 💵 Less expensive | 💵 Less expensive |
| Availability | Pro only (credits) | Free/Pro | Free/Pro |
| Best for | Personal, nuanced Qs | Quick, long answers | Balanced answers |
When Should You Use GPT 4.5?
Because of the credit limit and slower speed, GPT 4.5 isn’t what you want for every single question. I use it when I need to write something that shouldn’t sound like a bot—like emails, messages, or anything with a personal touch. If you just need quick facts or don’t care about tone, stick with GPT-4o or Claude 3.7 Sonnet.

The Cost Factor—Is GPT 4.5 Worth It?
Right now, GPT 4.5 is pricey. You only get 10 uses per day, and you need to pay for Pro. The hope is that costs will drop as the tech matures, but for now, it’s a premium feature. If you’re not writing sensitive messages all day, you might not need it. But if you care about tone and want your AI to sound less like a robot, it’s worth a shot.
