Is ChatGPT still free?

Hello there, I'm curious to know, has the availability of ChatGPT changed recently? Is it still offered as a free service, or have there been any updates regarding its pricing model? It would be great to get a clear understanding of its current status, as I've found the tool to be quite useful in my work. Could you provide me with the latest information on this matter? Thank you in advance for your time and assistance.
