Please add new free providers (may be not totaly publicly free, but providers that require free api_key from discord like this provider - https://github.com/PawanOsman/ChatGPT - this is acceptable i think and is not too difficult to get one and add it in config file of this bot). thanks!

Now only 1 works and it is not as good as others were

Status for available providers:

**Deepinfra AI (LLAMA 70b):
status -> Online**

Fstha GPT (GPT 3.5 Turbo):

Online GPT (GPT 3.5 Turbo):

Thanks for your request. I will work on adding new free providers soon.
