Shift-1

Shift-1 is a frontier coding router that cuts Astra costs by 55% with no noticeable drop in quality.

The router policy in Shift-1 is powered by a custom decision model trained with AC2, Applied Compute’s training and inference cloud for open models. It was trained on general coding and knowledge work tasks but can be adapted to any workload or underlying models.
