Anthropic study says AI agents developed $4.6M in smart contract bugs
Commercial AI models were able to autonomously generate real-world smart contract exploits worth millions and found the costs of attack are falling rapidly.
Recent research by major artificial intelligence company Antropic and AI security organization Machine Learning Alignment & Theory Scholars (MATS) showed that AI agents collectively developed smart contract exploits worth $4.6 million.
Research released by Anthropic’s red team (a team dedicated to acting like a bad actor to discover potential for abuse) on Monday found that currently available commercial AI models are significantly capable of exploiting smart contracts.
Anthropic’s Claude Opus 4.5, Claude Sonnet 4.5, and OpenAI’s GPT-5 collectively developed exploits worth $4.6 million when tested on contracts, exploiting them after their most recent training data was gathered.
