## Changes since last month

We found no confirmed price or free-tier changes in the 30 days to 13 October 2026.

## Method

We checked each agent's pricing on the vendor's own pages between 2 September and 13 October 2026: 149 of the 151 AI agents we list. The entry price is the cheapest paid plan, in US dollars a month. Yearly prices are divided by 12. 85 agents have one. Usage-based, one-time and quoted prices, and prices in other currencies, are left out of the medians. A free trial doesn't count as a free tier. A price change counts only when a later check saw it on the vendor's page.
