Rayline launches ARC, a tiny model that routes AI agent steps to the right model

AIRayline has launched ARC, a small AI model that picks which model handles each step of a task and how much it should think. In Rayline's DeepSWE tests, ARC scored 68.7% against 69.9% for Opus 5.5 while cutting cost to 7% per task.

Rayline has launched ARC, a tiny AI model designed to pick which model should handle each step of a task and how much it should think.

Users can send a task to ARC and have it automatically assign easy steps to a lighter model and hard ones to a stronger model, for a faster, more cost-efficient experience.

In Rayline's DeepSWE tests, ARC scored 68.7% versus 69.9% for Opus 5.5, while dropping the cost to 7% per task.

In 2015, I built an AI that detects early cancer. Today, we’re introducing ARC by Rayline: the world’s first unified model for routing AI. > 97.5% of Opus 5.5 quality > Up to 1/10th of the cost > Fully open-source It picks the right model and the right amount of thinking for every step of your agent’s work.
