Can I use OpenAI for free?

Hello there, I'm curious about the pricing options for OpenAI. I understand that OpenAI provides powerful AI tools and services, but I'm wondering if it's possible to use them without having to pay. Is there a free tier or a way to test out the platform before committing to a paid plan? I'd love to get a clear understanding of the pricing structure and any potential limitations or restrictions that come with a free account, if there is one. Thanks in advance for your help!
