Zero Data Retention (ZDR) means that a provider will not store your data for any period of time.

​
How Blackbox Manages Data Policies

Blackbox works with providers to understand each of their data policies and structures the policy data in a way that gives you control over which providers you want to route to. Note that a provider’s general policy may differ from the specific policy for a given endpoint. Blackbox keeps track of the specific policy for each endpoint, works with providers to keep these policies up to date, and in some cases creates special agreements with providers to ensure data retention or training policies that are more privacy-focused than their default policies.
If Blackbox is not able to establish or ascertain a clear policy for a provider or endpoint, we take a conservative stance and assume that the endpoint both retains and trains on data and mark it as such.

​
Per-Request ZDR Enforcement

You can enforce Zero Data Retention on a per-request basis using the zdr parameter in your API calls.

​
Usage

Include the zdr parameter in your provider preferences: 
curl -X POST https://api.blackbox.ai/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello"}],
    "provider": {
      "zdr": true
    }
  }'
When zdr is set to true, the request will only be routed to endpoints that have a Zero Data Retention policy. When zdr is false or not provided, ZDR enforcement will still apply if enabled in your account.

​
Caching

Some endpoints/models provide implicit caching of prompts. This keeps repeated prompt data in an in-memory cache in the provider’s datacenter, so that the repeated part of the prompt does not need to be re-processed. This can lead to considerable cost savings. Blackbox has taken the stance that in-memory caching of prompts is not considered “retaining” data, and we therefore allow endpoints/models with implicit caching to be hit when a ZDR routing policy is in effect.

​
Blackbox’s Retention Policy

Blackbox itself has a ZDR policy; your prompts are not retained.
