What is model poisoning?
Model poisoning is an attack where adversaries manipulate an AI model's training data or fine-tuning process to make it produce incorrect, biased, or malicious outputs. It compromises the model's integrity at a fundamental level.

How model poisoning works
Every feature designed to help your team work smarter with AI.
Training data manipulation
Attackers inject malicious or biased examples into training datasets that subtly alter the model's behavior.
Fine-tuning attacks
Compromise the fine-tuning process to introduce backdoors or biases that activate under specific conditions.
Backdoor triggers
Plant hidden triggers that cause the model to produce specific malicious outputs when certain inputs are provided.
Output validation
Monitor and validate AI outputs to detect anomalies that may indicate a poisoned model.
Supply chain security
Verify the integrity of models, training data, and fine-tuning pipelines to prevent tampering.
Anomaly detection
Track output patterns over time to identify sudden changes that may indicate model compromise.

FAQ
Frequently asked questions
Can model poisoning affect ChatGPT or Claude?
Major providers invest heavily in training data security, but no system is immune. The practical risk for most organizations is lower with major providers than with open-source or custom-trained models.
How does TeamPrompt help with model poisoning risks?
TeamPrompt adds a security layer between your team and AI models through DLP scanning and prompt governance. While it cannot detect a poisoned model, it protects the data you send to models and helps monitor usage patterns.
What is the difference between model poisoning and prompt injection?
Model poisoning attacks the model itself during training. Prompt injection attacks the model at inference time through crafted inputs. Both manipulate AI behavior, but at different levels.
