What GPT is known for

OpenAI's GPT models are the all-rounders most people met first: strong at writing, explaining, and code, with Pro and o-series variants that spend longer thinking on hard problems. The Mini and Nano versions answer faster and cost a fraction of the big ones.

How GPT works on Portail

Pick a GPT model from the model picker in any chat. It reads the whole conversation, including anything other models said earlier, and your Portail memory. When you want a second opinion, switch models and keep going, or turn on Council to ask several models at once.

Every plan, Free included, can use every GPT model. Plans change the size of your monthly credit allowance, not which models you can pick. Bigger models use credits faster; the cost band in the table shows roughly how fast.

Questions

How many GPT models can I use on Portail?

54 right now, from OpenAI. The list follows the live catalog, so new GPT models appear as they're added.

Can GPT read images?

42 of the 54 GPT models on Portail accept images. Check the Images column in the table.

Can I use GPT for free?

Yes. The Free plan includes every model, GPT too, with a starter credit allowance and no card. Cheaper GPT models stretch it further.

Is this the same GPT as in ChatGPT?

It's the same OpenAI models, reached through an API provider rather than the ChatGPT app. You get the model itself; ChatGPT-only extras like its own memory and custom GPTs stay in ChatGPT. Portail brings its own memory, which every model shares.

Do I need an OpenAI account or API key?

No. Sign up for Portail and pick a GPT model from the list. Usage comes out of your Portail credits.
