Enhancement: Add default model setting for each user

[TedLin1993]

What features would you like to see added?

Add default model setting for each user

More details

It seems LibreChat is missing the ability for users to choose a default model through the UI. This means that new chats always start with the model from the previous conversation. It would be great to have a default model setting;it feels like a core feature.

I've also experimented with modelSpecs to try and set a global default, but I haven't been able to get it working. Is there a way to set a default model in LibreChat? I'm hoping to use google gemini-2.0-flash-exp as the default.

Which components are impacted by your request?

Hoping each user can set default model by a button, like this:

Please give it a try, as this is the way to do it:

This is the minimal librechat.yaml configuration you would need for this (while still allowing all other features, providers, models):

version: 1.2.1
cache: true
interface:
  endpointsMenu: true
  modelSelect: true
  parameters: true
  sidePanel: true
  presets: true
  prompts: true
  bookmarks: true
  multiConvo: true
modelSpecs:
  enforce: false
  prioritize: false
  list:
    - name: "Google: Gemini 2.0 Flash Experimental"
      label: "Google: Gemini 2.0 Flash Experimental"
      showIconInMenu: true
      showIconInHeader: true
      default: true
      preset:
        endpoint: "google"
        model: "gemini-2.0-flash-exp"
        modelLabel: "Google: Gemini 2.0 Flash Experimental"

Make sure google is included in your .env file ENDPOINTS environment variable, as well as GOOGLE_KEY and GOOGLE_MODELS match expectations:

ENDPOINTS=google,agents
GOOGLE_KEY=someKey
# Gemini API
GOOGLE_MODELS=gemini-2.0-flash-exp,gemini-2.0-flash-thinking-exp-1219,gemini-exp-1206,gemini-exp-1121,gemini-exp-1114,gemini-1.5-pro-002,gemini-1.5-flash-latest,gemini-1.0-pro,gemini-1.0-pro-001,gemini-1.0-pro-latest,gemini-1.0-pro-vision-latest,gemini-1.5-pro-latest,gemini-pro,gemini-pro-vision

Hi @danny-avila,

Thanks for your response, this configuration worked as expected!

I have one further question: is it possible to omit the label field? I'd prefer not to have an extra label dropdown, as two dropdowns already feel a bit much, let alone three.
According to the documentation, the label should be optional, but it seems to be required in practice.

If each user can set their own default model, that will be better.

This can be done without model specs, using Presets:

That's great. Thanks!
