Using LibreChat with NanoGPT

A quick guide to setting up LibreChat with NanoGPT’s API.

Setup Instructions

Get your API key from nano-gpt.com/api
Locate your LibreChat installation’s librechat.example.yml file
Create a copy named librechat.yml
Add the following configuration to your librechat.yml:

# NanoGPT Example
- name: 'NanoGPT'
  apiKey: '${NANO_GPT_API_KEY}'
  baseURL: 'https://nano-gpt.com/api/v1/'
  models:
      default: [
        "openai/gpt-5.6-sol",
        "anthropic/claude-opus-4.5",
        "google/gemini-3-flash-preview",
        ]
      fetch: true
  addParams:
    reasoning_content_compat: true
  titleConvo: true
  titleModel: 'openai/gpt-5.6-sol'
  modelDisplayLabel: 'NanoGPT'
  iconUrl: https://nano-gpt.com/logo.png

LibreChat currently streams internal thinking from the legacy reasoning_content field. The addParams block above enables NanoGPT’s compatibility shim so LibreChat can render thoughts without additional changes. If you would rather not send the compatibility flag, you can instead point LibreChat at https://nano-gpt.com/api/v1legacy/ which keeps the legacy response shape by default.

Set your API key in your environment variables:
export NANO_GPT_API_KEY='your-api-key-here'

That’s it! Restart LibreChat, and you’ll have access to all NanoGPT models through the interface.
