Human Reviewers Read Real ChatGPT Sessions and Intimate User Chats
OpenAI employs hundreds of human contractors who review real ChatGPT prompts and full conversational transcripts. While usernames are hidden and automated filters strip identifiers, sensitive personal details still slip into evaluation queues.

Impact: High
Why it matters
Users frequently treat AI chatbots as confidants, assistants, or therapists without realizing that outside humans routinely read and evaluate unscrubbed conversation logs.
TL;DR
- 01Hundreds of contractors read real ChatGPT conversations to evaluate and rate model responses.
- 02Reviewers focus on reducing anthropomorphism and excessive model sycophancy.
- 03OpenAI attempts to scrub identifiers, but sensitive personal information still reaches human reviewers.
Key facts
- ChatGPT User Base
- More than 900 million users
- Peer Confirmation
- Anthropic confirmed using human reviewers to improve models
- Review Focus
- Training models to reduce sycophancy and anthropomorphism
Human Review of Real Production Chats
An investigation published by 404 Media revealed that OpenAI is hiring hundreds of contractors tasked with reviewing real user prompts and full multi-turn conversations from ChatGPT's user base of more than 900 million users. Anthropic also confirmed to 404 Media that it uses human review to improve its models.
Contractors evaluate generated replies to guide model behavior, focusing on key alignment issues:
- Curbing Sycophancy: Training models to be less sycophantic and avoid excessive validation of user statements, a problem linked in lawsuits to adverse outcomes with GPT-4o.
- Reducing Anthropomorphism: Training systems not to anthropomorphize themselves or present themselves as human-like entities.
Data Sanitization Limitations
Contractors do not see ChatGPT usernames, and OpenAI states that it attempts to strip personal identifiers before prompts reach reviewers. However, the company acknowledged that sensitive personal details can still get through.
Because users regularly share intimate details about their lives when treating chatbots as therapists, digital friends, or daily assistants, human evaluation pipelines present significant privacy implications.
