FAQ: LLM API Logging & Telemetry — What Enterprise CISOs Need to Know

What exactly does "LLM API telemetry" mean? When you call Claude API, ChatGPT API, or Groq, you send a request containing: Your prompt (the full text you want the model to process) Metadata (model name, parameters, tokens requested) Your API key (identifies your account/organization) Your IP address Your user agent (browser/app info) The provider logs all of this. That logging is called "telemetry." It's automatic and you can't opt out (unless you pay extra for Zero Data Retention mode). How long do LLM providers keep my prompts? Anthropic (Claude API) : 30 days standard 7 days for API logs (as of Sept 2025) Longer if policy violation or legal request Zero Data Retention (ZDR) available for enterprises (deletes immediately) OpenAI (ChatGPT API) : 30 days standard Longer for abuse investigation or legal compliance NOT used for training (as of March 2023) Groq : No published retention window (likely 30-90 days) No Zero Data Retention option Google Gemini API : "As long as necessary" for
