With the free tier of ChatGPT you hit output limits pretty much immediately. And with the fact that money is running out for OpenAI, I am willing to say the time for free LLMs and image gen models is not going to last too long. There is a reason why Gemini fucking sucks in the free tier, and somehow Copilot sucks even when paying (I am not crazy enough to pay for Copilot, I have it with a work license).
