Since ChimeraGPT works with LibreChat, and offers Llama2 along with OpenAI models, let's start with that one: [ChimeraGPT](https://discord.gg/ge48uqZUSr)
> ⚠️ Never trust 3rd parties. Use at your own risk of privacy loss. Your data may be used for AI training at best or for nefarious reasons at worst; this is true in all cases, even with official endpoints: never give an LLM sensitive/identifying information. If something is free, you are the product. If errors arise, they are more likely to be due to the 3rd party, and not this project, as I test the official endpoints first and foremost.
You will get your API key from the discord server. The instructions are pretty clear when you join so I won't repeat them.
Once you have the API key, you should adjust your .env file like this:
**Note:** The `OPENAI_MODELS` variable is commented out so that the server can fetch chimeragpt/api/v1/models for all available models. Uncomment and adjust if you wish to specify which exact models you want to use.
It's worth noting that not all models listed by their API will work, with or without this project. The exact URL may also change, just make sure you include `/v1/chat/completions` in the reverse proxy URL if it ever changes.
You can set `OPENAI_API_KEY=user_provided` if you would like the user to add their own Chimera API key, just be sure you specify the models with `OPENAI_MODELS` in this case since they won't be able to be fetched without an admin set API key.
### Plugins also work with this reverse proxy (OpenAI models). [More info on plugins here](https://docs.librechat.ai/features/plugins/introduction.html)
