Providers Guide: Connect AI Models to OmniRoute

TL;DR: A provider is a connection to an AI service (like OpenAI, Anthropic, Google). You need at least one provider to use OmniRoute.

What Is a Provider?

Think of a provider like a phone carrier. Just as you need a phone carrier to make calls, you need an AI provider to use AI models. OmniRoute is like a phone that works with all carriers — you can switch between them automatically.

Types of Providers

Web Cookie Providers

See WEB-COOKIE-GUIDE.md for general setup instructions, limitations, troubleshooting, and provider-specific authentication guidance.

Quick Start: Connect Your First Provider

Optional first-run free-provider setup

The first-run wizard offers an explicit Set up free providers card. It derives the current eligible list from OmniRoute's no-auth provider registry, then lets you review and deselect each provider before confirming. OmniRoute shows the provider's caution notice and a link to its site so you can review third-party terms, privacy, availability, and rate limits first.

This action is optional: finishing the wizard never creates free-provider connections silently. It creates only providers that are still missing, leaves existing customized connections untouched, and reports created, already-configured, and failed providers individually. You can safely retry only the failures after a partial result.

Option A: Free Provider (No Credit Card)

1. Open the dashboard at http://localhost:20128
2. Go to Providers → Add Provider
3. Select one of these free providers:
   • Kiro AI — Free Claude models (no auth needed)
   • OpenCode Free — Free GPT models (no auth needed)
   • Pollinations — Free GPT-5, Claude, Gemini (no key needed)
   • LongCat — 10M tokens free (one-time grant, requires account + KYC)
   • Cloudflare AI — 50+ models, 10K neurons/day
   • MLX Gemma 26B — Local Apple Silicon model (~38.5 tok/s, ~15.9GB RAM)
   • MLX Qwen 3.8 27B — Local Apple Silicon model (~9.1 tok/s, ~13.1GB RAM)
4. Click Connect
5. Done! You now have free AI access.

Option B: API Key Provider (Paid)

1. Get an API key from the provider's website:
   • OpenAI: https://platform.openai.com/api-keys
   • Anthropic: https://console.anthropic.com/
   • Google: https://aistudio.google.com/apikey
   • DeepSeek: https://platform.deepseek.com/
   • Groq: https://console.groq.com/
2. Open the dashboard at http://localhost:20128
3. Go to Providers → Add Provider
4. Select your provider
5. Paste your API key
6. Click Connect
7. Done! You now have access to that provider's models.

Option C: OAuth Provider (Subscription)

1. Open the dashboard at http://localhost:20128
2. Go to Providers → Add Provider
3. Select your provider (e.g., Claude Code, GitHub Copilot)
4. Click Connect with OAuth
5. Login with your account
6. Done! You now have access to your subscription models.

Option D: Local MLX Models (Apple Silicon)

For Apple Silicon Macs with unified memory, OmniRoute supports connecting to local MLX models running via mlx-lm.server as regular OpenAI-compatible local providers.

Prerequisites

• Apple Silicon Mac (M1/M2/M3/M4) with 24GB+ unified memory recommended
• uv package manager: curl -LsSf https://astral.sh/uv/install.sh | sh
• mlx-lm: uv pip install mlx-lm

Quick Start

1. Install dependencies:

   bashCopy

   # Install uv if not already installed
   curl -LsSf https://astral.sh/uv/install.sh | sh
   
   # Install mlx-lm
   uv pip install mlx-lm
   

2. Start MLX servers manually (in separate terminals):

   bashCopy

   # Terminal 1: Gemma 4 26B A4B IT-QAT (port 11435)
   uv run mlx_lm.server --model mlx-community/gemma-4-26B-A4B-it-qat-q4_0-mlx-aligned --port 11435 --host 127.0.0.1
   
   # Terminal 2: Qwen 3.8 27B MLX Mixed (port 11436)
   uv run mlx_lm.server --model maglun/Qwen3.8-27B-MLX-Mixed-3.80bpw --port 11436 --host 127.0.0.1
   

3. Connect in OmniRoute Dashboard:

   • Go to Providers → Add Provider
   • Select MLX Gemma 26B or MLX Qwen 3.8 27B
   • Click Connect (no API key needed)

4. Use with OpenCode:

   bashCopy

   # Configure OpenCode to use OmniRoute
   opencode config set api.base_url http://localhost:20128/v1
   opencode config set api.key <your-omniroute-api-key>
   
   # Use MLX models
   opencode run --model mlx-gemma/gemma-4-26b
   opencode run --model mlx-qwen/qwen3.8-27b
   

Memory Management

Important: With 24GB unified memory, only one large MLX model can run at a time.

• Gemma 26B: ~15.9GB peak memory
• Qwen 3.8 27B: ~13.1GB peak memory

You must manage this manually:

• Run only one MLX server at a time, or
• Run both on separate machines, or
• Stop one before starting the other

OmniRoute does not automatically manage MLX server processes — it only routes requests to the OpenAI-compatible endpoints you configure.

Tool Calling Support

Both models support OpenAI-compatible tool calling. Test with:

curl -X POST http://localhost:20128/v1/chat/completions \
  -H "Authorization: Bearer <key>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "mlx-gemma/gemma-4-26b",
    "messages": [{"role": "user", "content": "What is 2+2? Use the calculator tool."}],
    "tools": [{"type": "function", "function": {"name": "calculator", "description": "Calculate", "parameters": {"type": "object", "properties": {"expression": {"type": "string"}}, "required": ["expression"]}}}]
  }'

How to Connect a Provider (Step-by-Step)

Step 1: Open the Dashboard

Go to http://localhost:20128 in your browser.

Step 2: Go to Providers

Click Providers in the sidebar.

Step 3: Click Add Provider

Click the + Add Provider button.

Step 4: Select Your Provider

Browse the list or search for your provider. Click on it.

Step 5: Enter Credentials

• Free providers: No credentials needed — just click Connect
• API key providers: Paste your API key
• OAuth providers: Click Connect with OAuth and login

Step 6: Test the Connection

Click Test Connection to verify it works.

Step 7: Done!

Your provider is now connected. You can use it with model: "auto" or specify the provider directly.

Using Multiple Providers

OmniRoute works best with multiple providers. This gives you:

• Automatic fallback — If one provider fails, OmniRoute tries the next
• Cost optimization — OmniRoute picks the cheapest provider for each request
• Speed optimization — OmniRoute picks the fastest provider for each request
• Quality optimization — OmniRoute picks the best provider for each task

Recommended Setup

Connect at least 3 providers for the best experience:

1. One free provider (Kiro, OpenCode Free, or Pollinations) — Always available
2. One fast provider (Groq, Cerebras) — For quick responses
3. One quality provider (OpenAI, Anthropic, Google) — For complex tasks

Then use model: "auto" and OmniRoute will automatically pick the best one for each request.

Common Questions

"Do I need to pay to use OmniRoute?"

No! OmniRoute is free and open-source. You can use free providers (Kiro, OpenCode Free, Pollinations) without paying anything. You only pay if you choose to use paid providers.

"Which provider should I start with?"

Start with Kiro AI — it's free, requires no API key, and gives you access to Claude models. Then add more providers as needed.

"Can I use multiple providers at once?"

Yes! That's the whole point of OmniRoute. Connect multiple providers and use model: "auto" to let OmniRoute pick the best one for each request.

"What if a provider goes down?"

OmniRoute automatically skips failed providers and tries the next one. You don't need to do anything.

"How do I disconnect a provider?"

Go to Providers → click on the provider → click Disconnect.

"Can I use my existing API keys?"

Yes! If you already have API keys for OpenAI, Anthropic, Google, etc., you can use them in OmniRoute. Just paste them when connecting the provider.
