SlickGPT passes message history including a "context" or "system" message which it clearly explains to the user at the start of every chat. This is probably the most important thing the official chat.openai.com client fails to explain or expose to users directly.

But you can do all that with the OpenAI Playground for the chat API, and it supports GPT-4. I don't really see what your service adds to that.
