> Eligible API customers keep Zero Data Retention on frontier models. The new piece is Private Safety Processing: cross-session automated misuse detection that returns a narrow safety signal without exposing prompts to OpenAI staff. Early testers: Microsoft and Databricks. White paper planned for September.

Enterprises have been told they can have **frontier models** or **zero retention**, not both, once safety teams want a 30-day window. OpenAI is betting it can sell **Sol-class API** into regulated buyers by putting the monitor **on the customer’s side of the key**.

**OpenAI** published **Offering Zero Data Retention for frontier models**. Eligible **API** customers keep the ZDR promise: prompts and responses are **not retained** after a request; personnel **cannot review** customer content; enterprise data is **not used for training** unless the customer opts in. The new piece is **Private Safety Processing** — a preview of **cross-session** automated monitoring meant to work **with** ZDR, not replace it. **Consumer** ChatGPT Free / Plus / Go / Pro settings are **unchanged**.

## What shipped

| Item | Detail (OpenAI primary + Axios/TC/Bloomberg) |
|------|----------------------------------------------|
| **ZDR** | Eligible API / enterprise frontier deployments; no retained prompts or completions |
| **Private Safety Processing** | Automated pattern detection **across related interactions**; OpenAI staff see a **narrow risk signal**, not the underlying text |
| **Where content lives** | Customer-controlled infrastructure (ZDR) **or** OpenAI storage **encrypted under customer-held keys** (in development) |
| **Early testers** | **Microsoft** and **Databricks** (Bloomberg via Moneycontrol) |
| **Rollout** | Broader launch + **technical white paper** planned **September 2026** |
| **Spokesperson** | **Aleah Houze**, Head of Product Policy: risks now show up **over time**, not in a single prompt pair |
| **Exception** | Images flagged as potential **CSAM** can still be retained for legally required review even under ZDR |

Existing ZDR-compatible monitors scored **one request at a time**. PSP is OpenAI’s answer to **agentic, multi-turn** abuse without copying Anthropic’s **30-day retention** on covered frontier models (Fable 5 / Mythos 5) — the contrast Axios and TechCrunch drew the same day. Not Aug 7 Astra or Aug 18 pacing; this is **enterprise data-governance GTM**.

## Limits

- Architecture is **not public** until the September paper.
- Consumer ChatGPT is **out of scope**.
- ZDR eligibility is unchanged in kind; the news is the **frontier + PSP** pairing.
