Use Vercel AI Gateway as LLM Provider

Zed now supports Vercel AI Gateway as a language model provider, giving you access to multiple AI models through Vercel’s unified gateway interface.

What is Vercel AI Gateway?

Vercel AI Gateway is a service that provides a single API endpoint for multiple AI model providers. Instead of configuring each provider separately, you connect to the gateway which handles routing to different models.

How to Configure

Add to your settings.json:

{
  "language_models": {
    "vercel_ai_gateway": {
      "available_models": [
        {
          "name": "gpt-4",
          "provider": "openai"
        }
      ]
    }
  }
}

Then authenticate with your Vercel AI Gateway credentials when prompted.

Why Use AI Gateway?

Unified access: Connect to multiple model providers through one endpoint.

Cost tracking: Centralized usage monitoring and billing.

Rate limiting: Built-in rate limit management across providers.

Model switching: Easily switch between different AI models.

Enterprise features: Advanced logging, caching, and fallback handling.

Supported Capabilities

The provider automatically detects model capabilities from tags:

• Tool use (function calling)
• Vision (image understanding)
• Streaming responses

Models are configured with their supported parameters based on the underlying provider.

Use Cases

• Teams using Vercel’s infrastructure for unified AI model access
• Projects requiring multi-model support with centralized management
• Organizations needing detailed usage analytics and cost attribution
• Developers who want simplified configuration for multiple AI providers
