Adversarial methodology improves detection of AI-generated social bot content
Researchers introduce an adversarial framework that simulates malicious actors impersonating real social media users to generate training data for AI-content detection. The approach produces a multilingual, cross-platform dataset of paired human and AI-generated messages. Models trained on this adversarial data significantly outperform existing content-based bot detection systems on out-of-distribution real-world data.

How to Train Your Model Dynamically Using Adversarial Data
This Hugging Face blog post describes a methodology for dynamically training models using adversarial data, likely in the context of improving robustness against adversarial examples. The post covers techniques for generating and incorporating adversarial inputs during the training loop to improve model resilience. Published in mid-2022, it targets practitioners looking to harden ML models against distribution shift and adversarial attacks.
Attacking Machine Learning with Adversarial Examples
This 2017 OpenAI blog post introduces adversarial examples — inputs intentionally crafted to cause machine learning models to make mistakes, analogized to optical illusions for machines. It surveys how adversarial examples manifest across different input modalities and discusses the fundamental difficulties in defending against them. The post is an early foundational explainer on adversarial robustness from OpenAI.
New AI classifier for indicating AI-written text
OpenAI launched a classifier designed to distinguish between AI-generated and human-written text. The tool was positioned as an aid for detecting content produced by large language models. OpenAI acknowledged limitations including unreliability on short texts and non-English content, and noted the classifier should not be used as a sole decision-making tool.
A Holistic Approach to Undesired Content Detection in the Real World
OpenAI presents a holistic framework for building robust natural language classification systems aimed at real-world content moderation. The post outlines methodology for detecting undesired content at scale, addressing challenges of reliability and utility in production environments. This represents OpenAI's public disclosure of internal content moderation infrastructure and practices.
Robust Adversarial Inputs: Multi-Scale Fooling of Neural Network Classifiers
OpenAI researchers created adversarial images that reliably fool neural network classifiers even when viewed from varied scales and perspectives. This directly challenges the assumption that self-driving car vision systems are robust to adversarial attacks due to their multi-angle image capture. The finding has implications for the security of deployed vision systems in safety-critical applications.
Disrupting a Covert Iranian Influence Operation
OpenAI reports identifying and disrupting a covert Iranian influence operation that was using its AI models to generate content for political disinformation campaigns. The operation involved using ChatGPT to produce social media posts, articles, and other content intended to manipulate public opinion. OpenAI terminated the associated accounts and published details of the operation as part of its transparency efforts around AI misuse.
Testing Robustness Against Unforeseen Adversaries
OpenAI published a method to evaluate whether neural network classifiers can defend against adversarial attacks not encountered during training. The approach introduces a new metric called UAR (Unforeseen Attack Robustness) to quantify a model's resilience to unanticipated attacks. The work argues for measuring robustness across a broader, more diverse set of attack types rather than only those seen in training.
Disrupting Malicious Uses of AI | OpenAI Threat Report February 2026
OpenAI published its latest threat report examining how malicious actors are combining AI models with websites and social platforms for harmful purposes. The report analyzes detection and defense implications of these combined attack vectors. This represents OpenAI's ongoing effort to document and counter adversarial misuse of AI systems.
