Does an API not make economic sense for you? Personally I would rather use my own tooling (not VSCode based).
Would be great to have access to your model in a LLM gateway like https://openrouter.ai/
I would give your API a try as minimum.
ChatGPT amazed people but its UI didn’t. A bunch of better UI’s showed up building on the OpenAI API and ChatGPT own. They helped people accomplish more which further marketed the product.
You can get this benefit with few downsides if you make the API simple with few promises about feature. “This is provided AS IS for your convenience and experimentation.”
