Zero Data Retention (ZDR)

Maximum privacy mode where no query data is retained by AI providers.

What is ZDR?​

Zero Data Retention ensures:

  • AI providers don't store your queries
  • Data isn't used for model training
  • Responses aren't logged by providers
  • Maximum privacy protection

How It Works​

Without ZDR:

With ZDR:

Provider logs are disabled, and data is not retained.

Enabling ZDR​

  1. Open your chatbot
  2. Go to "Settings" > "Security"
  3. Toggle "Zero Data Retention"
  4. Click "Save"

ZDR-Compatible Models​

Whether a model is covered by ZDR depends on the model and the infrastructure provider serving it, not only on who made the model — the same model can be ZDR-covered through one provider and not through another. Providers also change their ZDR status over time, so WizChat doesn't rely on a fixed list.

Instead, WizChat checks each provider's current ZDR status in the AI gateway's live catalog. When ZDR is on, your chatbot is routed only to providers that currently offer zero data retention, and the fastest of those is preferred. The model pickers show which providers are ZDR-capable, so you can check before you choose a model.

Cerebras is not a ZDR provider

Cerebras no longer offers zero data retention, so ZDR chatbots are never routed to it. Cerebras models are still available for their speed on chatbots that don't need ZDR, and appear under Cerebras (Ultra Fast) in the model picker.

Spotting ZDR in the model picker​

When you choose the AI model for your chatbot — in the main model picker and in the per-tool model override picker — each model lists the infrastructure providers that can serve it, and a ZDR badge now appears next to any provider that offers zero data retention. This lets you see at a glance which model-and-provider combinations keep your queries out of provider logs before you pick one. You can also type zdr in the picker's search box to surface models with a ZDR-capable provider.
