Anthropic reverses course: keep your Claude logs in your own cloud
The retention Anthropic forced on you for safety is gone after pushback — but you now run the misuse-monitoring it used to. Also: OpenAI–Epic, Mistral OCR.

The forced-retention era just ended
Anthropic dropped the temporary data retention it required for safety checks — the policy The Register says cost it enterprise deals — after customer pushback. Its replacement, Enterprise Frontier Safeguards (EFS), landed Sept 1. If Claude holding onto your prompts was a blocker, that objection is now addressable.
Your logs live in your bucket, with your keys
Activity data goes to your own AWS S3, Azure Blob, or Google Cloud Storage — you hold the encryption keys and access policies, and no Anthropic employee reviews it; misuse alerts route straight to your security team. It's free from Anthropic; you just pay your cloud's storage and egress.
The catch: the monitoring is now your job
Zero-data-retention isn't automatic — you apply for it, and once EFS is on, its cross-session misuse detection (credential theft, cyberattack patterns) sends signals to you to review, not to Anthropic. The Register's blunt read: you now have to check it actually worked.
What's covered, and when
EFS spans Claude Code, Claude Platform and Enterprise, plus Amazon Bedrock, Google's Agent Platform, and Microsoft Foundry, on Fable 5, Fable 5.1, and Mythos-class models. Rollout is phased through fall 2026; eligible customers get interim ZDR on Fable 5/5.1 until it ships.
Elsewhere: OpenAI pipes Epic records into ChatGPT
ChatGPT Health can now import a patient's Epic EHR data (read-only) and pull public sources like PubMed, OpenAI said Sept 1. It's clinician-facing, not a builder API — but it signals where the assistant-plus-your-own-data pattern is heading.
Elsewhere: Mistral OCR 4.1 hits GA
mistral-ocr-4-1 is now production-GA, with a confidence_scores_granularity setting for page-, block-, or word-level scores — handy for flagging low-confidence extractions before they poison a RAG index.
