Update Model

Update an existing model's configuration on a live LiteLLM proxy.

Setup

LITELLM_BASE_URL  — e.g. https://my-proxy.example.com
LITELLM_API_KEY   — proxy admin key

Ask the user

1. model_id (required) — if they don't have it, list models first:

   curl -s "$BASE/model/info" -H "Authorization: Bearer $KEY" | python3 -c "
   import sys,json
   for m in json.load(sys.stdin).get('data',[]):
     print(m['model_info']['id'], m['model_name'])
   "

2. What to change — any combination of:
   • api_key (rotate the credential)
   • api_base (change endpoint)
   • api_version (Azure)
   • model (underlying model string, e.g. azure/new-deployment)

Run

curl -s -X POST "$BASE/model/update" \
  -H "Authorization: Bearer $KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model_info": {"id": "<model_id>"},
    "litellm_params": {
      "api_key": "<new_key>",
      "api_base": "<new_base>"
    }
  }'

Only include litellm_params fields being changed.

Output

Confirm the model was updated. Offer to run a test call to verify it still routes correctly.
