GPT-5 isn't actually that great

On Thursday, GPT-5 was released, and I thought, "Oh great, it’s a new version of GPT I can try!"

I have heard rumors about how GPT-5 is the real deal and how it will change the way AI tools work. However, in reality, it was underwhelming and not as impressive as expected.

It felt like a PR stunt, with GPT-5 being given to influencers for testing, and they all praised its greatness.

I considered trying it myself and getting my hands dirty.

I vibe coded an entire app with it.

I purchased a subscription to Lovable and started vibe coding.

The idea was to create an AI app that enables me to generate images using various AI models, such as ChatGPT Image Gen, Flux, Google Image Gen, and more, by using the APIs of Replicate.

You can see the project here: rep.fiaxe.com

The features I added are listed below:

1. Login & Sign up page

2. Authentication via Supabase w/ Google Auth Login

3. Image Generation for 66 Image AI models - Flux, Google Image Gen, GPT - Image Gen 1 & more.

4. Invite code system - It will be expensive if someone tries to access the app.

5. Magic Link Login

6. Forget Password Option.

When I decided to code these features, I didn’t actually know what I wanted from this app or whether I wanted these features or not.

When I began vibe coding, I encountered an issue I dislike the most: it hallucinates frequently.

It didn’t understand a lot of queries that I was asking to design.

Even after requesting the website to have a dark color scheme, it seemed that the AI did not understand my preferences.

I felt like bashing my head and began to question whether I made the right decision by purchasing a subscription to Loveable.

I asked the AI to create a header for me, and still, it wouldn’t understand.

If I ask the AI to do multiple things, it would fail and do only the task that is easy for GPT-5 to execute.

Here’s the entire app that I coded with the help of Lovable Screenshots below.

I’m not familiar with the Tailwind framework it uses, and for some reason, it lags a lot on my Mac. - Maybe the app has serious memory leak issues.

After a few hours I decided let’s give GPT-5 Google App Script coding to fix the formula which is use all the time =xai(instruction, range, model)

As usual, it failed miserably here too. It provided me with outdated code that is useful for GPT-4o but not for the latest version.

Now, looking at this I realised something.

That AGI is not gonna be that scary.

I hate those people who says that AI is gonna replace you.

It’s not gonna replace you but it’s gonna optimise you.

Learn a skill that can help you improve.

Purchase a subscription for tools, get hands-on experience, and try out the apps.
