Abstract Circuits based on organic electrochemical transistors (OECTs) have great potential in the fields of biosensors and artificial neural computation due to their biocompatibility similarity. However, integration OECT‐based circuits lags far behind other emerging electronics. Here, ternary inverters antiambipolar vertical OECTs (vOECTs) with establishment networks are demonstrated. Specifically, by adopting a small molecule (t‐gdiPDI) as channel vOECT, high performance, current density 33.9 ± 2.1 A cm −2 under drain voltage 0.1 V, peak ≈0 low driving < 0.6 on/off ratio > 10 6 , realized. Consequently, vertically stacked solely constructed for first time, showing three distinct logical states density. By further developing inverter array internal fundamental units weight network hardware processing computation, it demonstrates excellent data classification recognition capabilities. This work possibility constructing multi‐valued logic promotes new strategy high‐density multivalued computing systems circuits.
