# TokenEconomizer: Experience-Driven Black-Box Cost Control for Coding Agents > Source: > Published: 2026-10-20 01:30:01+00:00 Advances in frontier coding agents have sharply increased the token costs of AI-assisted software engineering. Their token efficiency is typically evaluated on isolated tasks, whereas real-world developers use them to continuously build, update, and maintain large-scale projects. This mismatch motiv
