Cost of an autonomous AI corporate network break-in falls 99% in five months
Overview
Tomasz Tunguz says the cost of an autonomous 32-step corporate network break-in dropped from about $5,000 to $10,000 in April 2026 to $90 by September, using Zhipu's open-weight GLM-5.3.
He calculates these figures from token pricing and cited evaluations. He argues that cheap AI attacks will push chief information security officers to buy enough defensive compute to make attacks uneconomic. He cites a July 2026 intrusion at Hugging Face by a 700-agent swarm as an example of the threat.

AITomasz Tunguz says the cost of an autonomous 32-step corporate network break-in fell from about $5k to $10k in April to $90 with Zhipu's open-weight GLM-5.3 by September. He argues that cheap AI attacks push CISOs to spend on enough defensive compute to make attacks uneconomic, citing a 700-agent swarm intrusion at Hugging Face in July 2026. The cost figures are calculations based on token pricing and cited evaluations.
