Ask HN: What GPT4 frontend do you use?

I'm curious to know which frontend alternatives you've been using to replace ChatGPT when working with the OpenAI API. As ChatGPT premium has a very low limit, I prefer to use the API but still want a similar (and hopefully better) UI.

My specific needs include:

- Token counting and cost estimation tools.

- Visibility into the sliding window of context in chat-style environments, as it's unclear which parts are considered in OpenAI's UI.

- Code compression and optimization techniques, such as stripping comments, removing irrelevant utility functions, or other methods often discussed here.

- Assistance with frontend coding: For instance, I struggle with managing React projects that have numerous files and require multiple changes for data passing. While the 32k model might help, it can be expensive.
