Auto Efficient

Auto Efficient sits inside Kilo's Auto Model lineup as the cost-optimized routing tier, positioned for work where the goal is the lowest spend per task rather than top-end capability. The tier is one of three Auto Model options, sitting alongside higher-capability and free alternatives, and is offered as a paid route designed for everyday development work inside Kilo Code. Because it operates as a routing abstraction rather than a fixed model, the exact underlying model behind any given request can shift over time as Kilo updates server-side mappings when better or more affordable options appear.

What makes Auto Efficient useful in practice is its session-aware classification, which judges the difficulty of each request in real time and steers it toward the cheapest model that Kilo's continuously-run benchmarks have shown to be accurate enough for that level of work. Routine tasks stay on lean, inexpensive models, while harder requests get escalated to a more capable one, giving developers a balance between price and reliability without manual configuration. Users who want to see which model actually handled a given request, along with its cost, can inspect the expanded model picker in Kilo Code or check the Gateway Model page, where current mappings are published.
