Which model to select to make use of enabled plugins

I have an existing plugin and when I use the chatgpt UI I get appropriate responses using that plugin. However, I have an application that is making api calls to the completions endpoint but I can’t figure out what the model name would be. I’ve used viewsource in the chatgpt ui to see both “text-davinci-003-plugins” and “gpt-4-plugins” listed but neither of those work returning Model does not exist errors.

What endpoints/models are available to use plugins via API.

Plugins are currently available and accessible only using chat.openai.com for users that have access.

Currently, based on my knowledge, plugins aren’t accessible on the OpenAI API.
