Access to models for free users

Hi to everyone. I am a student and not a native speaker of english. Sorry, if I bad in the language.
I decided to made my first telegram bot. Chatgpt telegrambot with gpt-4o, but have received an error(look at the picture
2025-01-04_23-56-14)
for starting my bot, of course, I registered on this website. Opened the tab “API keys” => Create new secret key, then used this API for my personal bot.
I guess that free API provide users with access to not all models. What models i can use for free? And how many does model gpt-4o cost? Unless, of course, I guessed correctly. If not, help pls, how can i solve the error.
Thanks

You can find more on rate limits and usage tiers here…

The quickstart is a great place to start too…

Basically, though, you’ll need to deposit at least $5 (which will expire a year after you buy it…)
