SWE-1.7: FRONTIER INTELLIGENCE AT A FRACTION OF THE COST

Summary from the TLDR AI newsletter

SWE-1.7 reaches frontier-level intelligence at a much lower cost. It is the result of broad improvements across Cognition's RL pipeline, including better infrastructure, more stable training, higher-quality data, and new techniques for long-horizon tasks. The model is available now in Devin on the web, desktop, and CLI. This post contains details on the infrastructure, algorithms, and data work behind the model.
