Coasty AI Agent Solves CAPTCHAs Up to Level 6, Sets New Benchmark
In a recent discussion on Hacker News, developers unveiled Coasty, a computer‑use AI agent that can solve CAPTCHAs up to level 6. The breakthrough demonstrates a significant leap in AI‑driven web automation, with Coasty achieving an 82% score on the OSWorld benchmark – the highest reported for a desktop‑environment agent.
Beyond CAPTCHAs, Coasty handles common web interruptions such as browser pop‑ups, cookie banners, and other UI obstacles that typically stall automation scripts. The team behind Coasty emphasizes that the agent was not explicitly trained on “I’m not a robot” challenges; instead, it learned to navigate them as part of broader task execution. A replay of the agent in action is available here.
This development has implications for both productivity tools and digital security. While the ability to bypass CAPTCHAs can streamline legitimate workflows, it also raises concerns about potential misuse. At Ubos Tech we are closely monitoring these advances and exploring responsible integration of AI agents into our platform.
