Unlocking GPT-5: Features, Pricing & More

Host

Welcome to Tech Talk Today! I'm your host, and in this episode, we’re diving into the exciting world of AI with a focus on the newly released GPT-5. It's been making waves, and I can't wait to unpack its features with our expert today.

Expert

Thanks for having me! GPT-5 is indeed a fascinating topic, especially for those of us who have been following the progression of language models.

Host

Absolutely! So, to kick things off, can you give us a brief overview of what GPT-5 is and how it fits into the OpenAI model family?

Expert

Sure! GPT-5 is essentially the latest iteration of OpenAI’s generative pre-trained transformers. What’s unique about it is that it operates as a hybrid model. It uses different systems for various tasks—there’s a fast answering model for straightforward questions, and a deeper reasoning model for more complex problems.

Host

That sounds really versatile! Can you explain what you mean by a 'real-time router' in this context?

Expert

Of course! The real-time router is like a traffic manager. It assesses the conversation's complexity and decides which model to use based on what the user is asking. If you, for example, prompt it with 'think hard about this,' it knows to engage the deeper reasoning model.

Host

That’s a great analogy! What about the pricing structure? How does GPT-5 compare to its predecessors?

Expert

The pricing is quite competitive! GPT-5 costs $1.25 per million tokens for input, which is actually half the price of its predecessor, GPT-4o. The output costs are similar at $10 per million.

Host

So, it's more affordable to use GPT-5, which is fantastic news for developers and businesses.

Expert

Exactly! There are also mini and nano versions of GPT-5, which are even cheaper, making it accessible for a wider audience.

Host

Speaking of the different versions, what can you tell us about the capabilities of the mini and nano models?

Expert

The mini model runs at a lower cost—$0.25 for input and $2 for output—while the nano model is even cheaper at $0.05 for input and $0.40 for output. However, they still retain significant functionality, allowing users to tailor their usage based on needs and budget.

Host

That’s fantastic versatility! Now, I heard you mention something about 'invisible reasoning tokens.' Can you explain what those are?

Expert

Invisible reasoning tokens are part of the output token count but aren't visible in the final output. They help the model maintain context and perform complex reasoning without the user seeing that extra 'thinking' process.

Host

I see! So, it’s like the engine running under the hood—powerful but not visible to the driver.

Expert

Exactly! It allows GPT-5 to provide smooth and competent responses without bogging down the user with unnecessary details.

Host

That’s such an insightful way to explain it! Lastly, what’s your overall impression of GPT-5 after using it for two weeks?

Expert

I find it to be a very competent model. It doesn’t feel like a dramatic leap, but it’s reliable and often impressive. It handles a wide range of tasks very well, which makes it a great tool for daily use.

Host

Thank you so much for sharing your expertise with us today! It sounds like GPT-5 is a solid addition to the AI landscape.

Expert

Thank you for having me! I’m excited to see how it continues to evolve.
