Vercel AI Gateway - Strix

Vercel AI Gateway provides access to 100+ models from multiple providers through one OpenAI-compatible API.

Setup

Create an AI Gateway API key, then configure Strix:

export STRIX_LLM="vercel_ai_gateway/zai/glm-5.3"
export LLM_API_KEY="your-ai-gateway-api-key"

The vercel_ai_gateway/ prefix selects the Gateway. The remaining value is the AI Gateway model ID.

Available Models

Access any model on the Gateway using the format vercel_ai_gateway/<provider>/<model>:
