What's your favorite interface for GPT API?

When you use OpenAI GPT API, you want an interface where you can quickly change model used, temperature, etc. and get results with nice formatting.

There might be extra features like prompt library/templates, text to speech, etc. Also, ways to send long chat history to the API without exceeding the context limit.

So what's you favorite? Free or paid.

For me, I found Chatbox [1] to be good for now. I tried ChatGPT Next Web [2] which seems to have advanced features but I couldn't learn how they work because most of the documentation is in Chinese. I tried Lore [3] a while ago and it seemed to have a great UX but when I wanted to try it again, I found that my trial was over and couldn't try it more nor know if it's still being updated.
