# safe_prompt on POST /v1/chat/completions is deprecated

Mistral deprecated POST /v1/chat/completions, body parameter safe_prompt without giving a shutdown date yet.

Mistral deprecated the body parameter safe_prompt on POST /v1/chat/completions without a shutdown date. Requests relying on this parameter will eventually fail once it is removed. Update your chat completion payloads to avoid interruptions when the parameter is turned off.

## What to use instead

Use Custom Guardrails in the request instead of safe_prompt.

- API: Mistral (api.mistral.ai)

## Mistral's words

> safe_prompt is deprecated. We recommend using Custom Guardrails instead, which provides more control over moderation categories and thresholds directly in your API requests.
