[Feature Request]: Add an API endpoint for refreshing Embeddings

[chevyriet]

Is there an existing issue for this?

What would your feature do ?

I am currently running 2 instances of the WebUI locally, and that (for performance reasons) both use different hardware for different tasks. I interact with those via a backend communicating with the API. When I create an embedding on one instance it needs a manual refresh (e.g. refreshing the browser window, using the button in the UI etc) before the other instance can use it.

As far as I know its currently possible to do something like refreshing via the API only for Checkpoints and VAE's, not for embeddings.

An API endpoint for refreshing the embeddings would be a big problem solver for not only my use-case but lots of others in terms of automation.

Proposed workflow

In my case:

1. Perform an operation on an embedding that needs a refresh to be accessed somewhere else (e.g. another instance)
2. Make a request to the corresponding URL for refreshing embeddings as shown in the API docs
3. Use the newly available embedding any way you want in your preferred location

Bad practice temporary solution I used for this:

• Everytime my application creates an embedding on one instance of the server, it also creates one on the other, which refreshes the embeddings list on that other instance.
• I gave this embedding a placeholder name like 'refresh' (or anything that is noticably different to your other "real" embeddings) with the property 'overwrite_old' set to true so that my embeddings list doesnt get cluttered with these refreshers.
• When showing the embeddings on my frontend I just filtered out the refresh embedding.

Here's how I built it（sdapi/v1/refresh-embeddings）in api.py, after refreshing the query in the api updated（sdapi/v1/embeddings）, but the ui content is not updated.All this is for reference only：

1. self.add_api_route("/sdapi/v1/refresh-embeddings", self.refresh_embeddings, methods=["POST"])

2. def refresh_embeddings(self): sd_hijack.model_hijack.embedding_db.load_textual_inversion_embeddings(force_reload=True)

This should be fine to close as done now. @AUTOMATIC1111 @chevyriet
