I just put this up to make people aware that they can use several free LLMs online via OpenRouter. It's a fully legit site I've used for almost 2 years, worth paying for service as well.

Anyways, download the OpenAI API off the workshop. Create your account on OR and then create an API key and copy it down.

In ChatWaifu, in the LLM tab under 'URL' enter - https://openrouter.ai/api
Key - Your API key from OR.

Update the list and pick one of the 'free' models. (You can see which ones are currently free on the OR site under the 'models' tab. Just arrange by pricing.)
