Vercel provider

You can proxy requests to Vercel AI models through AI Gateway by creating AI Model Provider and AI Model entities. This reference documents all supported AI capabilities, configuration requirements, and provider-specific details needed for proper integration.

AI Gateway automatically routes requests to the appropriate Vercel API endpoints. The following table shows the upstream paths used for each capability.

The following tables show the AI capabilities supported by the Vercel provider when configuring AI Models.

By default, AI Gateway uses the path templates shown in the tables below (e.g., /chat/completions, /embeddings, etc.). To customize these paths, configure the config.paths field in your AI Model entity. Custom paths take the form {configured_path}/{template_path} — for example, if you set a custom path of /v2, requests to /embeddings would be routed to /v2/embeddings.

Text generation

Support for Vercel text generation capabilities:

The base URL is https://ai-gateway.vercel.sh.

AI Gateway uses this URL automatically. You only need to configure a URL if you’re using a self-hosted or Vercel-compatible endpoint, in which case set the upstream_url option in your AI Model configuration.

To use Vercel with AI Gateway, configure a new AI Model Provider. You can then access supported AI Models from Vercel.

Note that, Vercel hosts models from other providers so in this example we use openai/gpt-5.5.

Here’s a minimal configuration for chat completions:

curl -X POST https://{region}.api.konghq.com/v1/ai-gateways/{AIGatewayId}/model-providers \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer $KONNECT_TOKEN" \
    --data '
