Kimi K3
The first open model to lead a frontier coding board.
Overview
The largest open-weights release to date, and the first open model to take the top spot on a frontier coding arena, ahead of closed flagships. Its SWE-bench Verified figure comes from an independent harness rather than the vendor, which makes it unusually well evidenced for an open release.
