Do you have an API that could be plugged into https://aider.chat/ ? It's by far the best way to use GPT4 for coding, in my experience, and more speed is exactly what it could use. But it needs an OpenAI compatible API.
Only reason I pay for ChatGPT Plus is because they have an API and I'm building products off of their API. I use Phind more for work, but I'm not going to pay anything unless they have an API.
