Point LibreChat at Tium
You need the base URL https://api.tium.ai/v1 and an API key from your dashboard. Keys are shown once at creation.
1.Add the endpoint to librechat.yaml
Custom endpoints live under endpoints.custom. Add the block above alongside any others you already run.
librechat.yamlendpoints: custom: - name: 'Tium' apiKey: '${TIUM_API_KEY}' baseURL: 'https://api.tium.ai/v1' models: default: ['glm-5.3-flash'] fetch: true titleConvo: true modelDisplayLabel: 'Tium'2.Put the key in your environment
The ${...} form reads TIUM_API_KEY from the environment rather than storing the key in the config. Set it to 'user_provided' instead if you want each person to supply their own.
What LibreChat gets wrong
Tool-specific behaviour that surprises people, and what to do about it.
fetch: true keeps the model list current
LibreChat can read the catalog from GET /v1/models rather than using the default list, so new models appear without a config edit. The default array stays as the fallback for when that call fails.
baseURL keeps its /v1 and nothing more
LibreChat appends /chat/completions to the base URL itself unless directEndpoint is set, so the value above is complete as written.
