 > ⚠️ 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.

 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.
