Allow hiding custom endpoints from user-facing model selection

[izabel-usheva]

Problem

I use a dedicated custom endpoint for conversation title generation through titleEndpoint and titleModel. This endpoint should remain available for title generation, but it should not be offered as a chat endpoint.

Currently, it appears in the model selector even though users are not intended to use it for conversations.

Proposed solution

Add an optional visible property to custom endpoints in librechat.yaml:

endpoints:
  custom:
    - name: 'Chat'
      # Other endpoint settings omitted
      titleConvo: true
      titleEndpoint: 'Title Generator'
      titleModel: 'title-model'

    - name: 'Title Generator'
      # Other endpoint settings omitted
      visible: false

When visible: false:

• Hide the endpoint and its models from the model selector, @ mentions, and the endpoint selector in the preset editor.
• Exclude it from automatic default endpoint selection, including restoring a previously selected endpoint from local storage.
• Keep it available for backend use through titleEndpoint.
  Omitting visible should preserve the existing behavior. This setting controls UI visibility and automatic selection, not access permissions.
  Implementation approach
  Apply the visibility rule in the shared endpoint mapping and default-selection logic so that all relevant UI entry points behave consistently.

Hey @izabel-usheva

did you already have a look at the modelSpecs config here?

I think that could solve your problem described here and also your problem with the user-friendly names, which you try to solve.
For reference, your PRs:

• feat: hide custom endpoint from dropdown with prop in the yaml #17058
• Feat/display friendly model names #16666

Let's assume you have some kind of config like this right now:

endpoints:
  custom:
    - name: 'Chat'
      # Other endpoint settings omitted
      titleConvo: true
      titleEndpoint: 'Title Generator'
      titleModel: 'title-model'
      models:
        default: ['chat-model-a', 'chat-model-b', ...]
    - name: 'Title Generator'
      # Other endpoint settings omitted
      models:
        default: ['title-model']
  openai:
    ...
  bedrock:
    ...
  agents:
    ...

I would suggest that you add the following modelSpecs to your librechat.yaml:

modelSpecs:
  enforce: false
  prioritize: true
  addedEndpoints: ["agents"]
  list:
    - name: "chat-model-a"
      group: "Chat"
      label: "Friendly Name for Chat Model A"
      default: true
      showIconInMenu: true
      showIconInHeader: true
      description: "Friendly description for Chat Model A"
      preset:
        endpoint: "Chat" 
        model: "chat-model-a"
        modelLabel: "Friendly Name for Chat Model A"
    - name: "chat-model-b"
      group: "Chat"
      label: "Friendly Name for Chat Model B"
      showIconInMenu: true
      showIconInHeader: true
      description: "Friendly description for Chat Model B"
      preset:
        endpoint: "Chat" 
        model: "chat-model-b"
        modelLabel: "Friendly Name for Chat Model B"

This will now give you two groups in your model-select dropdown in the Chat-UI:

• My Agents:
  • Here you'll find all your created agents
• Chat:
  • Friendly Name for Chat Model A
  • Friendly Name for Chat Model B

Furthermore, Friendly Name for Chat Model A will always be selected, when opening a new Chat. (default: true in the modelSpecs).

If you're not using the agents feature, just omit the line addedEndpoints: ["agents"].

But if you do also use the agents feature, I would suggest adding this in the endpoints config:

endpoints:
  ...
  agents:
    allowedProviders: ["Chat", ...]
    ...

Just list all endpoints in allowedProviders your users should be able to choose from, when creating new agents.
That way you can get rid of your Title Generator endpoint in the UI completely.

Hope that helps.
