Hi @chigwell, how can I learn more about LLM7? I found the webpage and Medium post. Access to LLM hosts + infra appears to be provided free of charge. Can you share how / why the project is financed, or what is the motivation for providing access for free? I imagine some potential users might be curious, and a bit more transparency here could help build trust and encourage adoption.

Hi @ccurme,

Thank you for reaching out with your questions!

LLM7 is funded through donations. We provide free access to our services to make advanced language model technologies more accessible to everyone. Additionally, anonymous user data collected may be used to improve model training.

For more clarity on how the project operates and is funded, I've added a detailed section at the end of the main landing page of the llm7.io website. Additionally, you can find comprehensive details regarding our operational principles, funding model, and user guidelines in our "Terms of Service" page, which is accessible here: Terms of Service.

Please feel free to reach out if you need any more information or have further questions.

Thank you!
