Frontier Radar #1: From chatbots to problem solvers - the state of AI agents in 2026

2025 was supposed to be the year of AI agents, and some say the revolution never happened. We see it differently: it did happen, just more quietly than expected. But what actually separates a real agent from a chatbot? In the first edition of our Frontier Radar Newsletter, we look at where things stand now: why success depends not just on the AI model itself but on the harness engineering around it, why agent swarms often fall apart when they hit the real world, and why unresolved security gaps are still holding back the dream of fully autonomous digital workers.
