URI ITS LLM Gateway

What is this?

The LLM Gateway is URI ITS’s centralized entry point for AI model access. It proxies requests to AWS Bedrock through LiteLLM, exposing a standard OpenAI Chat Completions API so existing tools and SDKs work unchanged.

• Per-user API keys tied to your URI identity, with tiered model access.
• Budget management — personal credit balances plus delegated budget pools and groups for teams.
• Cost & usage tracking — detailed per-model spend and token reporting.

Example uses

Any OpenAI-compatible tool works — point it at https://llmgw.its.uri.edu/v1 and use your personal key.

# Chat completion from the command line
curl https://llmgw.its.uri.edu/v1/chat/completions \
  -H "Authorization: Bearer $LLMGW_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "its_direct/pt3-claude-sonnet-4.6-1m-us",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

# pip install openai
from openai import OpenAI

client = OpenAI(
    base_url="https://llmgw.its.uri.edu/v1",
    api_key="sk-...",   # your gateway key
)
resp = client.chat.completions.create(
    model="its_direct/pt3-claude-sonnet-4.6-1m-us",
    messages=[{"role": "user", "content": "Summarize this..."}],
)
print(resp.choices[0].message.content)

// ~/.config/opencode/opencode.json
{
  "provider": {
    "llmgw": {
      "npm": "@ai-sdk/openai-compatible",
      "options": {
        "baseURL": "https://llmgw.its.uri.edu/v1",
        "apiKey": "sk-..."
      },
      "models": {
        "its_direct/pt3-claude-sonnet-4.6-1m-us": {}
      }
    }
  }
}

Compatible clients

The gateway speaks the OpenAI Chat Completions API. Any tool that lets you set a custom OpenAI base URL + API key works directly — point it at https://llmgw.its.uri.edu/v1.

Works directly (set base URL + key):

Via a router/proxy — for vendor-locked tools:

Tools tied to a specific vendor’s API (e.g. Google Antigravity — Gemini-only, Claude Code, Gemini CLI, GitHub Copilot) can connect through an OpenAI-compatible router such as 9router / n9router or CLIProxyAPI. Set the router’s upstream to https://llmgw.its.uri.edu/v1 with your gateway key; it translates the tool’s native calls to the gateway.

In every client, the model name must match what the gateway serves (e.g. its_direct/pt3-claude-sonnet-4.6-1m-us) — not generic IDs like gpt-4o. Full list in the portal.
