Q : “In your demo video you say you used ‘ChatGPT’s current best model o3,’ but the chatbot on your site says it’s powered by OpenAI’s newest thinking model o4. Which is it?”

A :

OpenAI publicly presents o3 as today’s flagship ChatGPT model. Through the developer API, however, we have early access to o4, the next-generation release. That’s the engine Johnny uses every time you chat—so the on-screen label is correct.

To show the difference, we recorded a side-by-side test:

Model

Total time to produce a solid answer*

o3 (public ChatGPT)

1 min 40 s — it first generated a long draft, then a second pass to validate its own answer.

o4 (Johnny)

≈ 30 s — delivered the solution in one shot, then rewrote it into a concise version.

*Same question, same network, no editing.

Because o4 thinks more efficiently, you get accurate replies in a fraction of the time—yet still pay less than ChatGPT Plus.
