DeepSeek and Custom endpoints configuration

[queengab]

What happened?

Description

DeepSeek and Custom endpoints are not visible in the UI under any configuration.

Google works correctly.
"My Agent" appears.
DeepSeek never appears (native endpoint, OpenRouter, or custom).

This seems related to LibreChat version 0.8.2 (Docker image).

Version Information

ghcr.io/danny-avila/librechat-dev latest 7ae222b04304 2 weeks ago 1.72GB
ghcr.io/danny-avila/librechat latest f4ca584739eb 4 weeks ago 1.68GB

Steps to Reproduce

Environment

• LibreChat version: v0.8.2
• Deployment: Docker (docker-compose)
• OS: Linux (Docker on NAS)
• Browser: Chrome
• Clean install (no legacy configs)

---

What Works

• ✅ Google endpoint works correctly
• ✅ "My Agent" appears in UI
• ✅ Gemini models respond correctly
• ✅ YAML config is loaded correctly (Google confirms it)

---

What Does NOT Work

• ❌ DeepSeek endpoint does not appear in UI
• ❌ OpenRouter endpoint does not appear
• ❌ Even when only Google is defined in YAML, adding DeepSeek changes nothing
• ❌ Adding OPENROUTER_API_KEY in .env does not make OpenRouter visible

      models:
        default:
          - "gemini-2.5-flash"
        fetch: false

When i try to add openrouter or deepseek or antropic endpoint, the yaml is loaded correctly, but i can't see nothing. If i add the endpoint in the .env file i can't use the menu to swtich from one AI to another. I have minimum credit in deepseek, claude and openrouter to test

    openrouter:
      apiKey: "${OPENROUTER_API_KEY}"
      models:
        default:
          - "deepseek/deepseek-chat"

When i try adding custom providers i receive

2026-02-25 20:00:55 error: Invalid custom config file at /app/librechat.yaml:

I updated the deepseek apikey placeholder correctly and delete ANTHROPIC_MODELS and now it works.

I also followed this blog post: https://www.librechat.ai/blog/2024-05-16_unsecured_http to use librechat locally without sessions expires.
Now i have all working.
Thanks so much.
Librechat is a great tool!

I don't think yaml file support google in endpoints, you can try delete them and find them still work
