Zero Data Retention

Zero data retention (ZDR) is available on AI Gateway. Set zeroDataRetention: true in providerOptions for individual requests to ensure they are only routed to ZDR-compliant providers.

AI Gateway has a ZDR policy and does not retain prompts, outputs, or sensitive data. User data is immediately and permanently deleted after requests are completed. No action is needed on the user side.

AI Gateway has agreements in place to offer ZDR with specific providers. A provider's default policy may not match with the status that AI Gateway has in place due to these agreements.

By default, AI Gateway does not route based on the data retention policy of providers.

You can enforce ZDR on individual requests using the zeroDataRetention parameter in providerOptions. Set zeroDataRetention to true to ensure requests are only routed to providers that have zero data retention policies.

If no ZDR-compliant providers are available for the requested model, the request fails with an error:

{
  "error": "No ZDR (Zero Data Retention) providers available for model: example/model-name. \
            Providers considered: provider-a, provider-b",
  "type": "no_providers_available",
  "statusCode": 400
}

When ZDR is enabled, the routing metadata in successful responses shows how AI Gateway filtered providers. The planningReasoning field indicates which providers were considered:

{
  "gateway": {
    "routing": {
      "planningReasoning": "ZDR requested: 5 attempts → 2 ZDR attempts. \
                            ZDR execution order: anthropic(system) → bedrock(system)"
    }
  }
}

ZDR enforcement also applies to any fallback providers.

This per request ZDR enforcement only applies for requests routed directly through AI Gateway (not BYOK). Since BYOK requests will go through your own API key, they fall under your current agreement with the respective provider, not the AI Gateway configuration with that AI provider.

Set zeroDataRetention to true in providerOptions:

import type { GatewayProviderOptions } from '@ai-sdk/gateway';
import { streamText } from 'ai';
 
export async function POST(request: Request) {
  const result = streamText({
    model: 'zai/glm-4.7',
    prompt: 'Analyze this sensitive business data and provide insights.',
    providerOptions: {
      gateway: {
        zeroDataRetention: true,
      } satisfies GatewayProviderOptions,
    },
  });
 
  return result.toDataStreamResponse();
}

import type { GatewayProviderOptions } from '@ai-sdk/gateway';
import { generateText } from 'ai';
 
export async function POST(request: Request) {
  const { text } = await generateText({
    model: 'zai/glm-4.7',
    prompt: 'Analyze this sensitive business data and provide insights.',
    providerOptions: {
      gateway: {
        zeroDataRetention: true,
      } satisfies GatewayProviderOptions,
    },
  });
 
  return Response.json({ text });
}

Set zeroDataRetention to true in providerOptions:

import OpenAI from 'openai';
 
const apiKey = process.env.AI_GATEWAY_API_KEY || process.env.VERCEL_OIDC_TOKEN;
 
const openai = new OpenAI({
  apiKey,
  baseURL: 'https://ai-gateway.vercel.sh/v1',
});
 
const completion = await openai.chat.completions.create({
  model: 'zai/glm-4.7',
  messages: [
    {
      role: 'user',
      content:
        'Tell me the history of the San Francisco Mission-style burrito in two paragraphs.',
    },
  ],
  providerOptions: {
    gateway: {
      zeroDataRetention: true, // Request only ZDR compliant providers
    },
  },
});

import os
from openai import OpenAI
 
client = OpenAI(
    api_key=os.getenv("AI_GATEWAY_API_KEY"),
    base_url="https://ai-gateway.vercel.sh/v1",
)
 
completion = client.chat.completions.create(
    model="zai/glm-4.7",
    messages=[
        {
            "role": "user",
            "content": "Tell me the history of the San Francisco Mission-style burrito in two paragraphs.",
        }
    ],
    extra_body={
        "providerOptions": {
            "gateway": {"zeroDataRetention": True}  # Request only ZDR compliant providers
        }
    },
)

Only the following providers offer ZDR on AI Gateway. Please review each provider's ZDR policy and terms carefully. A provider's default policy may not match with the status that AI Gateway has in place due to negotiated agreements. We are constantly coordinating and revising agreements to be able to enforce stricter retention policies for customers. The full terms of service are available for each provider on the model pages.

In special cases where certain models or functionalities are excluded from a provider's ZDR policy, AI Gateway will return an error explaining why the request cannot be completed with ZDR enabled. See the table below for exclusions and special cases.
